Daniel Defense Review: Almost All Their Guns

You might make a few assumptions when you spot a Daniel Defense logo on the firing line. Whoever brought it has quite a bit of dough to spend, appreciates the finer things, and probably knows how to shoot.

But is that all true? Daniel Defense has a reputation for being one of the better manufacturers in the firearm industry, but that doesn’t guarantee that everything the company builds is a home run.

Over the past few years, we’ve tested a heap of Daniel Defense products. We’ve hit the range with AR carbines, AR pistols, a bolt-action rifle, a suppressor, and even a nifty pistol Daniel Defense brought back from the dead.

Here’s what we learned from each one…

AR-15

DD4 RIII

When Daniel Defense rolled out the DD4 RIII, the company ditched the old quad-Picatinny rail setup for a slick M-LOK handguard with integrated quick-detach sling mounts. Only the top of the rifle has a Pic rail, which runs the full length of the upper receiver.

You can buy this upper and handguard as standalone items, too.

The controls on the DD4 RIII are all ambidextrous. The safety, magazine release, charging handle, and bolt catch/release are set up for right- and left-handed shooters out of the box. That also makes it great for ambidextrous use in close-quarters engagements.

We loved the DD4 RIII when we shot it. Read all about it in our hands-on review.

So, what’s not to like? The only thing stopping most people from buying a DD4 RIII is the price. This is a finely crafted firearm, and it’s not cheap to build.

It’s great to shoot, too. Check out this thing in action.

Daniel Defense lists an MSRP of $2,307 for the short-barreled rifle and $2,394 for the two carbine-length versions of the DD4 RIII.

DDM4 V7

Looking for a do-it-all AR-15 that’s light on weight and heavy on features? Allow me to introduce the Daniel Defense DDM4 V7.

High-end materials, a mid-length gas system, a 1:7 twist, and heaps of chrome lining ensure that the DDM4 V7 will flat-out run, even with harsh conditions, infrequent cleanings, and subpar ammo.

It’s sturdy, but it only weighs a tick over 6 pounds.

The $2,161 MSRP is steep, but there’s very little you’ll have to do to this rifle aside from mounting an optic and maybe a weapon light. It already comes with upgraded furniture, a 15-inch M-LOK rail with QD sling mounts, an ambidextrous safety, and a beveled magazine well.

The DDM4 V7 we tested ran flawlessly and accurately. It’s a perfect embodiment of “Buy once, cry once.” 

AR Pistols & SBRs

MK18

Want to run the same gun used by the military’s high-speed operators? You can — kind of. The Daniel Defense MK18 isn’t exactly what’s currently dropping baddies downrange, but it’s as close as you’ll get to the go-to AR of SOCOM.

It’s available as an SBR, a pistol, and an upper receiver. All feature a 10.3-inch barrel, quad-Picatinny rails (with comfy polymer covers), and a few color options to choose from.

This thing is built to be run hard – with or without a suppressor – and chew up whatever ammunition you feed it.

When we reviewed the MK18 at the ALERRT Training Center with Broaddus Defense, the only complaint we had was the unconventional grip angle. It’s a little shallower than a standard AR pistol grip, which takes some getting used to. The shape is helpful in confined spaces, though, which is presumably why Daniel Defense chose it.

DDM4 PDW

You want small? Daniel Defense does small.

A personal defense weapon (PDW) is typically just an AR pistol with the shortest barrel and most compact brace available. The DDM4 PDW comes with a rock-solid DDM4 lower receiver, a 7-inch barrel chambered for .300 BLK, and a Maxim Defense CQB pistol brace.

Perks include M-LOK and QD mounting points, a linear compensator to reduce the fireball associated with stubby barrels, and a handstop to keep your weak-side fingers from drifting in front of the muzzle.

This thing is practically begging for a suppressor (Daniel Defense designed it to keep subsonic .300 BLK ammo moving slowly), but it doesn’t require a tax stamp in stock configuration. Throw a red dot or holographic sight on the Picatinny rail and call it a day if you don’t want to deal with the extra hassle and cost.

When we tested the DDM4 PDW, it ran like a champ. Everything from the internals to the third-party components performed impeccably.

AR-10

DD5 V4

Don’t think we forgot about the mighty AR-10. We put a bunch of 6.5 Creedmoor rounds through the Daniel Defense DD5 V4  in testing, with positive results.

The DD5 V4 is also available in 7.62 NATO. As with any AR-10, you’ll take on some extra weight and reduced capacity in the name of a heavier-hitting cartridge than the AR-15 can deliver.

This isn’t just an enlarged AR-15. The gas block, bolt carrier group, dual ejectors, barrel, and charging handle are all upgraded to improve performance with a harder-hitting round.

Our only complaint came as a result of the mil-spec trigger; it feels like a step down from the rifle’s overall feel.

At the range, our test rifle performed absolutely perfectly and showed why Daniel Defense charges an MSRP of $2,731 for the DD5 V4.

Other DD5 options now include an SBR in 7.62 NATO and a newer DD5 V5 that adds a sweet camouflage pattern and supports .260 Rem.

Bolt-Action

Delta 5 Pro

I was psyched to see Daniel Defense drop a precision rifle, but building extremely accurate bolt guns is very different from making high-end ARs. We learned a lot from our range time with the Daniel Defense Delta 5 Pro.

Like other chassis guns, the Delta 5 Pro is modular. Swap barrels, change cartridges, and customize fit to your liking. It checks the usual boxes with a bedded action, a 20-MOA rail, 10 (!) QD points, an M-LOK rail, and a standard AR-style grip you can replace with a huge selection of aftermarket options.

Daniel Defense offers six variations of the Delta 5 Pro (plus three colors), but they collectively serve only three cartridges: 6 Creedmoor, 6.5 Creedmoor, and .308 Win. The starting MSRP for all of them is $2,574.

Not everything impressed us upon initial inspection, though. More barrel offerings would be nice. The grip angle and adjustable thumb rest weren’t the most ergonomic. The factory case seemed like an afterthought.

To be fair, my precision rifle shipped in a cardboard box, and most of us are going to buy something like a Pelican Vault V800 and fill it with a Magpul DAKA grid organizer, regardless of what the rifle comes in.

Testing out to 950 yards resulted in a few odd malfunctions, but there’s no denying that the Delta 5 Pro is incredibly accurate. Do your job, and it’ll put rounds on target.

Daniel H9 Pistol

Editor’s Note: This article was written before we tested the H9. We have since had an opportunity to test and review it, so Editor-in-Chief Jacki Billings provided this section.

While Daniel Defense is known for rifles, the company ventured into the handgun market in 2024 with the release of the Daniel H9. Building on the abandoned Hudson H9, Daniel Defense’s version looked to elevate the build with some added features.

The Daniel H9 offers a 15+1 capacity and an extremely low bore axis paired with a unique recoil spring placement that makes it a flat shooting pistol. Ergonomics were top tier, and our reviewer loved the way the Daniel H9 felt in the hand while shooting.

Nice touches like a green fiber optic front sight and a rear serrated black steel rear along with a crisp trigger were highlights during our experience.

It’s not without its issues, though…reliability being chief among them. It took three returns before we were able to get a working model. But once we did, it worked well.

To their credit, Daniel Defense has acknowledged the issues and is working to fix them.

Suppressed

DDM4 ISR

There’s something special about an integrally-suppressed AR. The sight of a can peeking out of a long handguard gets us fired up like the smell of napalm in the morning.

The Daniel Defense DDM4 ISR is more than just an AR, a suppressor, and a pretty handguard, though. It’s backed by the research and development necessary to make the firearm and suppressor work optimally together.

Everything from the .300 Blackout cartridge to the 9-inch cold hammer-forged barrel was designed in the pursuit of suppressed performance.

While the suppressor is fixed to the barrel, Daniel Defense designed it so that the core can be removed for cleaning. That’s a big advantage over pinning a non-serviceable can to your AR pistol to make it a carbine.

The best part? Because the suppressor is integrated, the overall length of the system keeps it out of SBR territory. You’ll still need a tax stamp for the suppressor, though.

Gripes? We have two. First, the DDM4 ISR only comes with a Keymod handguard, and most people these days probably prefer M-LOK. Second, the $3,562 MSRP is hefty, even if it’s justified.

The DDM4 ISR is still one hell of a firearm, though, and it impressed us when we shot it.

SoundGuard Suppressor

Daniel Defense got into the suppressor game in 2022. The SoundGuard line of suppressors includes one can for 5.56 NATO and two for .30-caliber rifles.

The standard 5.56 NATO and .30-caliber SoundGuard suppressors are full-auto-rated. The titanium .30-caliber suppressor is not. All three attach via universal mounting hubs and have flat sides for a wrench.

Patent-pending baffles dramatically reduce sound levels and all but eliminate any visual signature.

The downside of running a suppressor is that, while audible and visible effects are reduced, the additional backpressure sends hot (and probably unhealthy) gasses directly into the shooter’s face.

Daniel Defense countered this by designing the SoundGuard line to vent as much gas forward as possible. There are also threaded ports around the end of the can that you can leave open for maximum airflow or selectively fill with set screws to fine-tune directional discharge.

We noticed a significant reduction in blowback during our hands-on review of the SoundGuard line.

And the best part? SoundGuard suppressors are surprisingly affordable. Daniel Defense lists an MSRP of $773 ($1,030 for the titanium version), and retail prices are even lower.

Daniel Defense quality at an extremely competitive price? Yes, please!

Final Thoughts

So, does Daniel Defense deserve the hype? In a word, yes.

While everything we’ve tested isn’t perfect (keep in mind that some of the complaints we had are subjective), everything performed reliably and accurately. If anything is worth paying for, it’s a firearm that you can trust to put rounds exactly where you want them every time.

There are other great manufacturers, and you can always build a custom AR however you want it. But as far as off-the-shelf options go, Daniel Defense has earned our stamp of approval.
