    Better than expected

    Posted by Chase on 28th May 2026

    i had shot the p365 flux and knew i wanted to get into something similar. Debated the flux 320, Taurus pdw, but eventually ended up on this. I’d love to see some more promo and people reviewing this, because it’s way better than i would have thought it to be. The build quality is really solid, feels good and weighty, but not so heavy that it’s not easily carry-able in a bag. It has less snap than the 365, but still a snap. It busied me up pretty good with around 250 rounds through it in one session, but this isn’t a “shoot thousands of rounds through it in a day”. It’s an equalizer, it’s a “me versus the bad guy, I now have the bigger stick”. Im not pro shooter, but it instantly gave me tighter groupings. I only used irons at first, but i can imagine it’s even better with a red dot. Super happy with my purchase, and I’ll for sure be recommending it to anyone who’s interested. A great option for those wanting a bag gun, truck gun, or new home defense weapon.

    Great overall

    Posted by Eric on 28th May 2026

    This chassis system is what got me to purchase an RXM, I always wanted a little PDW like this that works with Glock parts and magazines. Fit and finish is very good overall, mine was very snug on the FCI installing it. Only critiques is that the magwell can be tight with some magazines when fully loaded. I would really like to see a way to add a flared base to the reaper for magazine changes, though that would partially be to get some more real estate for my pinky with the G19 grip length.

    Sweet

    This is a dope little pdw chassis. Super compact and tight in all the right spots. Fit is great finish is questionable. Mine is scratching easily so be careful but idgaf, i like a tool that has been used. This is a cool little blaster chassis that lets you to run your fun glock accessories. A bit overpriced but i prefere to give my money to the small business doing cool shit so again idgaf

    Rxm reaper

    Posted by Scott Sutherland on 25th May 2026

    I have both reapers in 365 and rxm. The rxm one is amazing (they both are good). Literally nothing about it that I would change. Perfect. Sorry flux your late to the game.

    Reaper RXM

    Posted by Jared Ramsey on 13th May 2026

    Got my first one in Monday, ordered a second one today. I never gave the RXM a second look until I discovered the reaper. Although I Like the 19 size grip, I look forward to a full size grip version in the further. Although the current size is by far more versatile. Fit and finish are excellent. Cross bar safety is done right. If you are like me and like the concept of a chassis that takes glock mags, look no further.

    Reaper Chassis

    Posted by 65th Tactical on 29th Apr 2026

    I’m not a review type of guy but! Man I’m I impressed with the JL Billet Reaper Chassis, the craftsmanship is on the money, it’s very sleek design draws the attention, even though the texture isn’t super aggressive the grip it self provides plenty of adherence to the hand, the controls are very intuitive and user friendly and they work smoothly, they brace deployment is very swift. I love that it fits in a small size sling bag which I’m sure they thought of given it includes a safety button which it place in an easy to reach area. The reaper is nothing short of amazing. If you don’t have an RXM get one or get the FCI! You will not be disappointed.
