Meta Tactical APEX Bullpup Carbine Conversion Kit for Glock 17 Gen 3-4 (9mm)

Meta Tactical's APEX bullpup carbine conversion kit for the Glock 17 Gen 3-4 (9mm) turns the pistol you already own into the heart of a compact carbine. Meta Tactical calls it the first-ever bullpup-style conversion system. The kit pairs the APEX-Series chassis with a 16-inch drop-in barrel that is slim, precision machined and finished in black nitride.

Confirm fit first. This version is built for Gen 3 and Gen 4 Glock 17 pistols. It does not support the Glock 17L with its 8.86-inch long slide, or Gen 2 models that have no front rail. Most aftermarket and optics-ready Glock slides work, but the optic has to come off while the pistol is in the chassis.

The bullpup layout keeps overall length short. The kit is fully ambidextrous, from the magazine release to the non-reciprocating charging handle and shell deflector. An integrated cheek rest, a 6-position adjustable stock and support for standard AR-15 A2-style flat-top grips let you tune the fit, and suppressor-height sights are supported.

The chassis weighs 2.771 lb and the barrel .454 lb, about 3.25 lb before your pistol goes in. Choose Black or FDE Tan. Meta Tactical makes the APEX in the USA and says it complies with federal firearm regulations. State and local rules on these kits vary, so check yours first; OSS America doesn't ship to states that restrict them.
