Description
The AMP is FAB Defense's newest generation of pistol conversion chassis, and it fixes the one gripe people had with older kits like the KPOS G2: the closed top. This one runs an open upper design, so if your Glock 17 or 19 wears a slide-mounted red dot or you just want to keep using your factory sights, nothing gets in the way. This FX-AMPSL-10A1B-BP configuration comes set up for the G17 and G19 and includes the SL side-folding stabilizing brace in black.
What Makes the FAB Defense AMP Different
FAB Defense builds the AMP as a hybrid of aluminum and high-density polymer, which is a smart split. You get a rigid, repeatable platform for optics and accessories without the boat-anchor weight that all-metal chassis tend to carry. The handguard runs M-LOK slots along the sides plus a Picatinny section, and the included MA3 rail segment gives you a spot for a light, laser, or a larger optic out front. Getting your pistol in and out is a single-button snap-lock affair. No tools, no gunsmithing, no permanent changes to your Glock. Press, seat, done.
A Modular Chassis That Grows With You
Here's the part that makes the AMP a long-term buy: the rear adapter is replaceable. This kit ships fitted for the Glock 17 and 19, but FAB Defense makes adapters for a bunch of other popular pistols, so one chassis can follow you through different handguns down the road instead of collecting dust when you switch platforms.
Running the AMP SL Brace Kit at the Range
With the SL brace deployed, a stock Glock becomes noticeably easier to stabilize, and follow-up shots tighten right up. Fold the brace and the whole package stays compact enough to stash in a small bag. It comes from the same Israeli company that has been building duty-grade accessories since 1969, and their gear gets run hard by military and police units around the world, so the fit and finish here is what you would expect from people who build for professionals.

Frequently Asked Questions
Will the FAB Defense AMP work with a red dot mounted on my Glock slide?
Yes, that is one of the AMP's biggest selling points. The open-top design leaves the slide fully exposed, so slide-mounted optics and even your factory iron sights stay usable with the pistol installed. Older closed-top kits forced you to run a separate optic on the chassis, and the AMP does away with that.
Do I need any tools or gunsmithing to install my pistol in the AMP conversion kit?
No tools and no modifications needed. The AMP uses a single-button snap-lock system, so your Glock 17 or 19 drops in and locks up in a matter of seconds. It comes back out just as fast, and your pistol stays completely stock the whole time.
Can this AMP kit be used with pistols other than the Glock 17 and 19?
This configuration ships with the Glock 17/19 adapter installed, but the AMP was designed around a replaceable rear adapter system. FAB Defense offers adapters for a range of other pistols including SIG, HK, CZ, Walther, and Taurus models, so the same chassis can be reconfigured if you change handguns later. Adapters are sold separately.
Does the brace on this kit fold?
It does. The SL stabilizing brace folds to the side, which keeps the whole package short and easy to pack in a bag or case. Deploying it takes just a second when you are ready to shoot.
