Overview

The Palmetto State Armory 16" CHF M4 Carbine upper receiver is built around a hammer-forged chrome moly vanadium barrel produced by FN—referred to as "machine gun steel" due to its use in M249 and M240 weapons. The barrel is chambered in 5.56 NATO with a 1/7 twist rate, a carbine-length gas system, an M4 barrel extension, a low-profile gas block, and an A2 flash hider, and is high-pressure tested and magnetic particle inspected. It is housed within a 13.5-inch PSA lightweight M-LOK free-float handguard and mated to a 7075-T6 A3 MIL-SPEC forged upper receiver finished in black hard-coat anodizing. Note that this upper receiver does not include a bolt carrier group or charging handle.
