Our G-Block kit delivers a market-first capability: now you only need a 9mm or .40 S&W upper with Glock-cut bolt and a milspec AR15 lower to shoot using Glock mags. The cost of buying a pistol-caliber carbine has just been cut in half.
The G-Block requires no permanent changes to your lower. With the included cutting guide, Glock magazines* can be altered to interface with any milspec AR15 magazine catch in under a minute. TorkMag's G17 magazines are also compatible out of the box with AR mag catches. Each kit ships with polymer magwell blocks mated to a steel fixed ejector, a mag-cutting guide, and a hex key for press fitting the magwell blocks in position.
*TorkMag strongly advises modifying only OEM Glock factory magazines.
