M-LOK vs KeyMod
One of the first decisions you’ll make is which attachment system…M-LOK or KeyMod. It used to be a personal preference, but recently USSOCOM (US Special Operations Command) released the results of their testing.
And M-LOK is the clear winner due to much better impact test results.
Best Free-Floating Handguards
Free-floating handguards are your best bet if you are building your own AR-15 upper.
These give you an accuracy advantage since it doesn’t contact the barrel…so your hand position and extra gadgets, such as bipods, don’t affect barrel harmonics.
Plus, you can choose any handguard length if you have the right low-profile gas block for it to go over. I personally like ~12-inch handguards with 16-inch barrels since I use the c-clamp grip.
To get a better grasp on the best length for you, check out our guide to choosing the proper handguard length.
1. STNGR USA Handguards
The STNGR VYPR is the handguard that recently bumped Aero off my Best Bang-For-The-Buck handguard list.
You get a really nice 13.5-inch M-LOK handguard. The VYPR is the most “standard” looking one and what I’d recommend.
Install was standard, and there are some strong-feeling anti-rotation tabs built into the handguard.
Fit/finish/color was top-notch, and my only initial worry was that the top cuts were too aggressive/large, so a finger could slip through.
However, after a bunch of mags, I found that it was fine (unless you have really thin fingers). And no problem if you C-Clamp grip it.
Check out the video:
The logo isn’t too pronounced either, which I like.
Plus, there are sometimes some blemished versions, so you can save even more if you don’t care to have a “perfect” rail.

What’s your take on the VYPR? Rate it below.
*Update* The lesser-railed VLCN has become the basis of our night vision build (after a little paint job).
And we love it…the slick upper side makes it easy to mount buttons.
Check out how modular it can be in our Cable Management video:
Want a little more style?
There’s the HWK handguard which gives a more aggressive “prong-ed” look and the ability to add a light/laser to the bottom with the included rail.
I think it could look really cool with a 14.5-inch pinned barrel so it sits flush with the cutout.
Plus, it’s only a few bucks more than the VYPR for the 13.5-inch and 15-inch variants.

I also tried out their rail covers which are definitely more affordable than other name brands — comfy and cool looking too.
I personally like the look of the Cyclops more, but the Gecko is probably the more useful one to maintain a good grip.

One of my current favorite best-bang-for-the-buck free-floating handguards (but now my 2nd pick).
Here it is on their new upper that I’m testing (full review).
I love how it saves weight by not having a full Picatinny rail on top.
Plus, the taper at the front perfectly fits my thumbs.
Note that the top where the rail would have been is rounded, so if you’re thinking of putting a pressure pad for lights…you’re out of luck.
Otherwise, the price vs fit/feel is perfect.
- Length: 12″
- Handguard Weight: 7.0 oz
- Barrel Nut Weight: 4.7 oz
- Total Weight: 11.7 oz
And now Aero has the full-rail version if you have more gizmos that need attaching.
Only negative about the Aero handguards is that sometimes (especially after a seasonal sale), they are out of stock for a while.

This latest generation lightweight handguard includes a full Picatinny rail on top. If you need to attach more things…this is our favorite pick.
Comes with seven sides of M-LOK attachment capability.
I’ve been using the older version of this (non-M-LOK) for years as my primary competition rifle handguard. Check out the left two uppers.
- Length: 12.625″
- Total Weight: 9.9 oz
4. AT3 Tactical Quad-Rail
If you’re needing lots of Picatinny real estate or want something nostalgic with a little bit of modern…check out AT3 Tactical’s Quad-Rail.
There’s some lightening cuts to bring down the weight and also give it a faux-M-LOK look.
Plus 5 QD attachments points so you can sling up however you want.
And see those tabs? They give a great fit and prevent rotation on any mil-spec forged upper receiver. And also fit in perfectly with AT3’s billet uppers.
They come in a bunch of lengths too: 7″, 9″, 12.5″, and 15″.

When you absolutely positively have got to have the lightest handguard. It was the best performing BY FAR in our Lightest Handguard roundup.
Combined with a pencil 14.5″ barrel…this AR was nearing 5 lb territory.
But keep in mind that you won’t be able to add anything to it…and since it is cylindrical all the way through…you’re going to have a harder time bracing against barriers.

6. Tyrant CNC Nexgen 15″ AR Handguard
This handguard from Tyrant CNC checks a lot of boxes for features and design. Made from 6000 series aluminum, the Nexgen 15″ Handguard comes with a custom barrel nut and wrench for installation.
M-LOK slots are located in the 12, 3, 6, and 9 o’clock positions, and short Picatinny rail sections can be found near the receiver and muzzle. There are also QD slots on both sides, near the front and rear of the rail.
One of the coolest features is the rubber grip panels plugged into the bottom that provides exceptional grip. These are removable by sections in case the shooter wants to utilize the M-LOK slots instead.
Tyrant has abused these handguards to make sure they stand up, including drop tests, torsion, hot and cold cycles, and even 10,000 rounds of fire using semi and full auto.

7. Midwest Industries Night Fighter
Want to reduce possible laser shift on your handguard?
The Night Figher from Midwest Industries is worth taking a look since it was designed from the ground-up to minimize impact shift from the most popular IR lasers.
I’ve been running it for over a year on my primary night vision rig that’s been through courses and many night shoots.
I’ve had multiple drops and countless dings…and it’s still exactly zeroed as the first day with my DBAL A3.
Install was just like any other free-floating handguard and there’s a variety of lengths.

Drop-In vs Free-Floating Handguards
If you have a delta ring and a front sight base (FSB)…your best bet is to go with a drop-in unless you want to shave down the FSB and remove the delta ring.
You’re also limited in handguard length by the FSB. Here are a couple of the most popular lengths.
Many of them come in two pieces, which are placed on the gun and screwed together to prevent the need to take off the barrel.
The biggest advantage of going with a drop-in handguard is simplicity.
You shouldn’t need to make any modifications to your AR-15 when installing a new drop-in handguard, and since they’ve got a relatively simplistic design, they’re usually cheaper than their free-float counterparts.
Best AR-15 Drop-In Handguards
First off, if you’re looking for a fancy handguard with extra frills, the Magpul MOE M-LOK isn’t for you.
As you can probably tell by its price, this handguard is pretty simplistic – and for good reason.

What you get with the M-LOK is a heat-resistant polymer handguard that’s hardy enough to handle your clanging and banging and comfortable enough to grip.
Despite its simplistic design, the M-LOK has slots on its 2, 6, and 10-o’clock positions where you can mount an optional Picatinny rail system. But what you’re really getting when you go for the M-LOK is a lightweight handguard that can withstand anything you throw at it.
At around $30 for a mid-length gas system…I think that’s a good deal.

Pricing
Note…I don’t have any “cheap” rails on this list. I’ve tried out a bunch of great deals I’ve found at gun shows and especially on Amazon and Ebay. The rails look great when they come in…but something has always been off:
- Attachment system sucks (too heavy, too many screws, etc)
- Doesn’t align correctly to the upper receiver
- Picatinny rails are not mil-spec (stuff doesn’t fit onto them)
I have a box of holsters and cheapo rails now that sit in the back of my shed. Learn from my fails…you get what you pay for in rails.

Handguards have been a focus on AR's since the first issued quad rail on an M4, and it's purpose was to mount dozens of optional sights, lights, and grips the DOD was authorizing for a wide variety of MOS's. Point being, on a 14.5" barrel, long distance accuracy from a short range combat weapon was way down the list of improvements. Being a universal mount was the first intent.
We don't use them for that anymore, civilian weapons are comparatively stripped down. Maybe a grip, sling attachment point, or a light, done. Maxed out combat internet rifles have come and gone, all the gear is heavy and most of it relatively uneeded for defense. Hunting, a light/laser can be illegal - I don't keep my pic rail for a light mounted on any hunting rifle, it's on the home defense AR pistol, where it can be used.
Things have changed over the last 15 years and the Apex I mounted on the 6.8 has resulted in discovering some issues. In fall/early winter, an aluminum handguard requires a glove on the off hand - it can soak up heat quickly, even turn frosty out of the vehicle while acclimatizing to 20F temps. They also ring like a bear bell in brush. My next deer rifle build, Im moving back to GI clip in polymer guards to cut down noise and make them comfortable to handle. As for accuracy, shooting within 250m, and largely under 125, with NO SLING an AR will be effective. Scope/red dot is the better improver than a $125 accessory mount, and that kind of money can and will buy an LPVO now. When you have to prioritize your expenses, compare which delivers more bang for the buck. Fancy handguards aren't all that - they are more a snapshot of the current merchandising of accessories than a guarantee of hitting the target. Some skill is required . . .
I don’t understand why so many people report that the Troy hand guard doesn’t line up properly with the upper receiver. I’ve had the Troy Enhanced Battle Rail for probably 13 years and it not only locks up as solid as you could imagine but it lines up perfectly with zero issues.
Hey Eric, Great review as always. If I could throw another one, it would be the Odin Works R2 or their standard forend. Cheers
FYI Brownells' website lists a 2.5" section of Picatinny rail and mounting hardware available from the manufacturer which is available for mounting things to this hand guard.
Good reviews! I have more than a few brands from BCM, SLR, Daniel Defense, Midwest, and STNGR. The STNGR VLCN is very nice. Parallax Tactical has a good rail with rails on all sides (5 slots) at the front for lights, bipods etc. Each brand serves it's purpose well with no complaints.
I been using the Midwest Industries G4 m-lok on my builds lately.
I have a 12.5" on a patrol and like the weight and added QDs at the front. nice and light for the length and Mloks all around d minus 12oclock.
Drop in- B5 lightest cheapest needs some attention cleaning up edges and such but it literally weighs near nothing. And on a sub 5 pound build it's the only value way to do it.
I like the Aero rails too, but the inside diameter only allows for using the Aero gas block
That's not accurate. I built a 6.5 grendel using an Atlas handguard and SA adjustable gas block.
yikes. If JuStAsGuD could write an article, it would be this one.
Please add Knights Armament RAS to the drop in section.
I have the UTG Pro "13" free float on a custom build with Vltor upper and Daniel Defense pencil barrel with Vltor low profile gas block. I can vouch for the quality it's solid and never given me a problem. I like good stuff but I can't pay hundreds of dollars for a damn hand guard. I just found out that they now sell a titanium barrel nut and hardware for mounting it which I think I may get. It's about $60.
I'm not sure the weights on the STNGR handguards are accurate. I got excited because this review lists the weight of the STNGR VYPR 15" at 11.5oz. That beats the Atlas S-One 15" by about 1oz, at about $20 less. Except, something doesn't add up.
STNGR lists the weight as 10.15ounces + 3.49ounces nut, for 13.64 ounces total https://www.stngrusa.com/vypr-m-lok-free-float-handguard-15-ar15-m4/
That matches the weight shown here without nut as 10.15 ounces.
https://stngr.zendesk.com/hc/en-us/articles/360019834573-Precise-Handguard-Lengths-and-Weights-
That would make it 1 ounce more than the Atlas S-One 15" at 12.67ounces. In this range of handguards, I think I'd still pay more for the lighter, more proven Atlas. Even more so if you can manage to find a blem.
to hell with Troy Industries, they hired that Ruby Ridge sniper, the son of a

Have you ever tested the VISM M LOK drop in handguard? Looks like a nice option at around 65 Bucks. I'm looking for a inexpensive drop in mlok handguard and it would be nice to hear your opinion about it, if you have any.
Can I install Magpul MBUS flip up front sight on Atlas S-on MLOK Handguard
Yes, I have a magpul MBUS on an Atlas S-One rail
I’ve been running UTG Super Slim free float for about 3 years, reasonably priced and solid.
Glad to STNGR in the running and winning BEST BANG for the BUCK!! BUT..... How you can you NOT mention the RPTR???? HOLY SH*T BATMAN!!!.. Between the RPTR and the HWK, I'm not sure which I like better!! I too put the 15" HWK over a 14.5" barrel....so...sweet... Got the 8.25" RPTR on a 7.5" 9mm.. muzzle device just peaks out past the RPTR.. They are my favorite hands down...
Great site brother. Excellent resource.
Thanks! Glad we can help!
I was considering a BCM Upper, interested to know your reasoning for excluding their MLock rail? I have not had time to touch one yet and would be interested in some feedback to keep in mind when I start touching them.
Check out STNGR...seriously.. They make great rails at a great price. Nothing wrong with BCM, if you want to pay for them..
I own several AR platform rifles and I enjoy the light weight Brigand arms hand guard. Very light and strong.
WIsh I could afford one!! Good to hear!
Love the hand guard but I wished it would have matched the rest of my fde, it looks more grey than fde!!
This is one of the best sites i have come across when it comes to inhaling knowledge about guns and handguards, thank you for helping out a newbie like myself!
Glad we could help!
It would be interesting to see how the super cheap M-Lok handguards on ebay stack up to the much more expensive competition.
Eric and team PewPew, I have been enjoying your up-to-date articles and reviews for a couple of years now. Thank you! My first question is an easy one. I am looking for a drop-in and wonder why you specified the Leapers-UTG model 4 (mtu015ss) and no mention of the M-Lok version (mtu015ssm). The M-Lok version seems to have more versatility but wonder if you tested and concluded it didn’t have the same durability as the Pro model 4?
Hey! That M-Lok version seems to be the upgrade to the regular model. It should be good to go! We'll be updating the article shortly.
I understand you wanted to only list M-lock due to the study you mentioned. But a lot of people are set on key mod due to some gear they already have, or what they can pick up used from a buddy since everyone is jumping to M-lock. I would have appreciated like a "JV team" listing of good key-mod options. For example: Bootleg Pic-mod.
Thank you for creating this site! I'm a noob and this is exactly what I've been looking for to learn.
Our pleasure, Jose! That's exactly why we're here.
My favorite does not seem to get much love on the interwebs: the ALG Defense EMRv2 M-Lok. Relatively cheap at ~$150, light at 9 oz. for the 13" model, no rails to add weight or cut my fingers (except for the front BUIS), 1.75" diameter, and M-Lok slots EVERYWHERE. You can hang anything you want on this rail with the M-Lok slots without the weight penalty of quad rails. Designed by Bill Geissele and sold through his wife's company ("ALG" stands for Amy Lynn Geissele), it is simply an excellent piece of kit that does not get the publicity it deserves.
Is it possible to use a low profile adjustable gas block with the magpul drop-in hand guard?
Unfortunately no, as the magpul drop-in MOE handguard is designed to attach to an A2 front sight post.
Yes. it can be done. It may look odd sitting in front of the handguard. But all that is required it the use of the standard handguard front end cap installed behing the low profile gas block
I only wish that the author had taken more time to evaluate the handguards for heat transfer especially with high throughput and handling in a cold environment, If I had to guess, the $30 Magpul might prove an overall better choice than some of the milled metal options.
Good point, next time! I don't multiple mag dump to really heat it up...but 60 round rifle competition stages are all fine through these handguards.
You said that you can't add attachments to the Brigand Carbon handguard but they make 2.5" picatinny sections you can put on it.
Here is what it says on the link you provided:
"Want to add some accessories? No worries, check out the Brigand Arms 2.5" Picatinny Rail Segment, sold separately. Allows you to add as few or as many accessories as you'd like while maintaining a lightweight rail. It comes with a special backing plate to make sure any accessories you add remain secure at all times."
You're right!
But you can't use it up front for a BUIS. But they do make them now with attached rails just for that.
WOW! You have listed some expensive gear, Eric. Name brand, but expensive.
I bought two hand guards from Mentium-USA with steel nuts for less than $125. They are located in Houston TX. I just checked out their website and they are growing! Check them out. I'm not affiliated with them - just a satisfied customer.
Thanks Steve, I haven't heard of Mentium but maybe I'll check them out.
I've had bad experiences with cheaper rails from gun shows and Ebay. They sit in a box in the back of the shed now.
Please do not refer to the AR as an assault weapon it’s not an assault weapon by Definition. You lose credibility when you do this
Thanks, fixed!
I love all your post, but I feel you played a few favorites in this one. Maybe like you said it's just the Handguards that you are familiar with. That's fine you always write a good blog.
I wish you would try a Fortis, also an Odin. I just put an Odin on an F1 308 skelonitized build and the mounting system was one of the best I have ever used. Thanks and keep up the good work.
Brian H
Hi Brian, I've tried out a Fortis Night Rail before...but the attachment system was really difficult and I bent one of the front rails the first time I brought it out.
I’ve purchased 2 from Unique ARs out of Idaho. One of their stock models and one I designed. I think they are worth a look. Good article btw
Thanks Sparky!
I've been curious about that Brigand Arms carbon fiber. Thanks. Great article.
Love my Geissele & SLRs. Not cheap though.
That's for sure! My handguards get all beat up so I try to balance best-bang-for-the-buck.
Have you looked at the STNGR rail systems? Would be interested to see how they stack up to the competition in your opinion. Love mine, as I have purchased 2 so far and will be using them as my go to rails in the future. Very similar design to Spike's and the Aero Atlas.
Never heard of them but I just looked at their site. Style remind me of Fortis. Will keep in mind for future builds.
Hey Paul, thanks...I haven't heard of them but may try them out in the future.
