Ultra-Compact PDW Stock for AR-15 5.56/.223 Builds
The VERT-V2-PDW-556 is designed specifically for AR-15 rifles chambered in 5.56/.223 using a standard direct-impingement system. It uses a patented ultra-compact buffer and spring that allows the stock to collapse to just 4.8 inches overall while still running a standard M16 bolt carrier group—no proprietary BCG required.

Whether you’re building a home-defense PDW, a truck gun, or a tight, fast-handling SBR (where legal), this stock system dramatically cuts length while preserving reliability and shootability.
