Strike Industries FDE Picatinny Stock Adapter for AR-Platform

The Strike Industries Picatinny Stock Adapter in Flat Dark Earth (brand part no. ARPSAFDE) converts a standard AR lower receiver’s threaded buffer tube interface to a Picatinny rail mount, letting you run a folding stock or stabilizer instead of a fixed buffer tube. It threads directly into the standard 1 3/16-16 HSS right-hand thread on the rear of the lower and includes an anti-loosening detent that stays positive and tactile while keeping the rear takedown pin’s detent spring properly captured. A 4-slot Picatinny rail section handles the stock or stabilizer mount, and a 360-degree free-swivel QD socket lets you position your sling mount to either side. It’s a straightforward way to build an AR upper as a self-contained unit and quickly configure the lower for a folding or Picatinny-mount stock.
