This kit consists of the most commonly worn, broken, or lost parts that will shut your AR15 rifle or carbine down. Contains a firing pin, firing pin retaining pin, cam pin, gas rings, and extractor assembly with mil-spec Viton O-ring. All parts are housed in a 3-D printed insert that snaps conveniently into Magpul MOE grips.  This is the only insert module available that also includes a broken cartridge extractor.

The extractor assembly and gas rings are on an insert that can be replaced with a complete bolt head assembly.   

Can accept a complete AR-15 bolt head or an extractor assembly and gas rings. 

These grip inserts are 3D printed in a glycol-modified copolyester that is impact and chemical resistant and and withstands temperatures over 80° C (176° F) without warping. 

Inserts are black with the ADC logo in green ( a little lighter than Magpul green), and tan (a little lighter than Magpul FDE).  Other color configurations are available on special request.
