Armaspec XPDW Stock Gen 2 – AR-15 Platform

The Armaspec XPDW Stock Gen 2 is an ultra-compact PDW-style stock designed for AR-15 platforms where reduced overall length is critical. This stock compresses to just over 5 inches, making it ideal for vehicle deployment, confined spaces, or building a compact AR pistol into an SBR. Unlike traditional carbine stocks, the XPDW uses a captured buffer spring system housed in the stock body itself, allowing for significantly shorter receiver extension and overall package length.

Constructed from reinforced polymer with aluminum reinforcements at stress points, the Gen 2 features improved latch durability and smoother length-of-pull adjustments compared to the original design. The stock requires the use of Armaspec's proprietary buffer tube and buffer system (sold separately). Installation requires disassembly of the existing buffer tube, buffer, and spring—straightforward for anyone comfortable with basic AR maintenance. The black finish matches standard AR furniture.
