Description
This mil-spec AR 15 Pistol Kit combines a heavy-duty 10.5” barrel with a lightweight, 12” M-Lok handguard to afford shooters with optimal velocity and accuracy in a compact configuration. Included is a completely lower parts kit featuring a polished, enhanced trigger and lower parts kit.
You’ll also receive a 5-position buffer tube with an ergonomic SB Tactical pistol brace to improve shot group placement and reduce felt recoil. All components in the kit feature mil-spec fittings and finishes for a perfect match.
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.
