Strike Industries AR Picatinny Stock Adapter 6061-T6 Aluminum FDE - AR-15/AR-10

The Strike Industries AR Picatinny Stock Adapter replaces the standard buffer tube on Mil-Spec AR-15 and AR-10 ArmaLite/DPMS-pattern lower receivers, opening up a compact 4-slot Picatinny rail for mounting stocks, pistol braces, or accessories. Machined from 6061-T6 aluminum with an anodized Flat Dark Earth finish, the adapter threads directly into a standard AR rear 1 3/16"-16 HSS right-hand thread and uses an integrated anti-loosening detent to stay put under recoil.

Built for shooters who want a short stock or brace mount on a bufferless lower, the AR-PSA ships with both a buffer bearing (BB) plug for lowers that retain a buffer and a coin stack spacer for true bufferless configurations. At just 3.0 oz and measuring 2.05" long x 1.42" wide x 0.94" tall (1.21" at the threaded shank), it adds minimal length and weight while turning your rear takedown into a usable Picatinny mounting point.
