Palmetto State Armory
Complete short .338 ARC AR-pattern pistol with the PSA 8.5-inch upper, a 7-inch M-LOK rail, HAR-15 stabilizing blade, and the correct DuraMag magazine.
0-10 Scale Across 8 Axes
The PSA 8.5-inch .338 ARC pistol is the complete-firearm version of the upper already used in the catalog's .338 ARC build path. It combines a short 4150V nitride barrel, pistol-length gas system, and 7-inch M-LOK handguard with a standard AR-pattern lower. The included bolt uses the 6.5 Grendel Type 2 face required by .338 ARC, so a standard 5.56 bolt is not a substitute.
The pistol also ships with the correct 10-round DuraMag. That detail matters because .338 ARC feeds from the .400 Legend DuraMag geometry rather than a normal 5.56 magazine. The 1:8 twist follows the general .338 ARC specification and handles both the cartridge's supersonic and heavy subsonic loads.
This is built as a short suppressor host. The 5/8x24 muzzle thread accepts compatible mounts, but the suppressor must have enough bore and an explicit .338 ARC rating. A typical .30-caliber can is too small for the .338-inch projectile.
