Any time I see a serialized trigger group, my gears start turning. It’s a blank canvas for creating new firearms – as long as other manufacturers get on board, that is.
Now, the JL Billet Reaper chassis is available for the Ruger RXM. That means you can turn your compact carry pistol into a beefed-up personal defense weapon in a matter of seconds. You don’t even need to hassle with an FFL to do it!

The Reaper chassis is compatible with the Ruger RXM trigger group, slide, and magazines. Using it basically means swapping out the factory grip module.

Since the RXM is a clone of third-generation Glocks, you can also use Glock 19 Gen 3 and Glock 17 Gen 3 slides and magazines with the Reaper.
Unlike many pistol-based chassis systems, this one isn’t polymer; it’s carved from a block of aircraft-grade aluminum and then anodized (I sure would like some more color options down the road).
The Reaper includes a manually deployable brace, removable blast shroud, manual cross-bar safety, and room for a spare magazine. There’s also a left-side QD point for adding a single-point sling.

With the brace folded, the system measures just 9.68 inches long and 1.65 inches wide. That makes it pretty compelling for concealed carry in a small CCW backpack or sling.
You can run the same red dot on your slide as you normally do, and the Picatinny rail makes installing a light quick and easy.

JL Billet lists an MSRP of $479.95 for the Reaper RXM chassis, but introductory pricing is listed as $459.95.

My 2 cents. Don't name items with terms that give anti's more talking points. As a lifelong enthusiast (call me a fudd I don't care) This is not helpful. We are not "gun nuts" let's not act like it. How about "fun stick"?
What are you referring to, Mike?
"The Reaper" sounds like a fun sporting tool. WTF don't you understand?
Mike, I was trying to understand what, specifically, you take issue with because your comment is unclear. Your unprovoked hostility toward people on your own side of the 2A issue seems more problematic than a third party's naming conventions. Thanks for the engagement.
Ok thanks!
Good article Scot, I just have 1 question: is the Reaper chassis compatible with any other pistol?
I mean other than the Glocks already mentioned.
Hi John, JL also makes a Reaper for the Sig Sauer P365. You can check it out here.
