Light as a pistol, sends heavy subs downrange with ease.
This ultra-light "Honeycomb" 300 Blackout AR Pistol Kit includes a uniquely designed free-float handguard that reduces forend weight as much as possible. Machined from billet aluminum, the M-LOK handguard houses a pistol-length gas system and recessed flash can for reliable cycling and proper flash suppression.
This kit's upper, lower parts kit, and buffer assembly are compatible with any mil-spec stripped lower receiver, or fabricated AR-15 80% lower.
Note: Due to ATF rule 2021R-08F, any pistol with a stabilizing brace is considered a short-barreled rifle (SBR), and is therefore considered a National Firearms Act item requiring a federal tax stamp.
What’s Included
This kit is not a firearm. It includes an assembled upper receiver, bolt carrier group, lower parts kit, and buffer assembly with pistol brace.
