Alex Pro Firearms | APF Proof SS Pistol 223 Wylde 30rd

The APF Armory Proof SS Pistol is an AR-style pistol chambered in 223 Wylde and built around a Proof Research stainless barrel and an AR pistol configuration without a brace. It ships with a 30-round Magpul PMAG, a 12.5″ M-LOK handguard, A2 pistol grip, and an M16 nitride bolt carrier group. For a compact optic under $1,000 that pairs well with this platform, consider a Holosun 507C red-dot for fast target acquisition and a low mounting profile. Typical uses include range training and competition shooting where a compact AR pistol footprint is preferred.
