Welcome to Palmetto State Armory!
Once upon a time, a "dissipator" AR was created by taking a 20" rifle-length gas system upper and cutting the barrel down to 16". This allowed the shooter to keep the long sight radius of a rifle for accuracy, but keep the carbine length barrel for maneuverability. The proximity of the gas port to the muzzle, however, played havoc with timing and made reliability a hit or miss proposition. Advances in AR technology have produced reliable carbine and mid-length gas systems, that can be hidden using low-profile gas blocks. This allows for a front sight base to be pinned in the rifle position for the longer sight radius without the worry of the unorthodox gas port location affecting operation. We use the term "mock" to differentiate our dissipator from a cut-down rifle length version.
Our Hammer-Forged Mid-length mock dissipator uses a "Machine Gun Steel" barrel that is thick chrome-lined for durability and high pressure tested and magnetic particle inspected.
Everything you need to turn your stripped lower into a rifle for one low introductory price. Kit includes a PSA 16" Hammer-Forged, Chrome-Lined, mid-length mock dissipator upper, BCG, charging handle and our standard Lower Build Kit.
Lower Build Kit: Includes a PSA M4 stock, A2 Pistol grip, Palmetto State Armory Lower Parts Kit with single-stage combat trigger, Mil-Spec diameter buffer tube, castle nut, end plate, carbine spring, and PSA Standard buffer.
Barrel: A proprietary blend of Hammer forged chrome molly vanadium made by FN that is referred to as "Machine Gun Steel" by virtue of its use in FN's M249 and M240 weapons. The hammer forging process work hardens the steel, making it more durable. In addition, the chrome process for the bore allows for a lining almost twice as thick as a standard M16 for enhanced durability. Chambered in 5.56 NATO, with a 1/7 twist, M4 barrel extension, and a Mid-length gas system. A2 style profile barrel is Mil-spec phosphate coated, High Pressure tested and Magnetic Particle inspected. Barrel is finished off with a pinned F-marked front sight post pinned in the Rifle position with sling swivel, rifle length handguards, and an A2 flash hider.
Upper: Forged 7075-T6 A3 AR upper is made to MIL-SPECS and hard coat anodized black for durability. Featuring machined T marks, and a mil-spec finish. These uppers are made for us right here in the USA by a mil-spec manufacturer, and are marked with the Palmetto State Armory logo on the left side, up front, just below the rail.
Bolt: Bolt is made of Mil-spec shot-peened Carpenter 158 steeI. Gas key is secured with grade 8 fasteners and staked per mil-spec. Bolt carrier is parkerized outside, chrome lined inside, and laser engraved with the Palmetto State Armory logo.
Each upper is assembled to order with care, and test fired.
