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.

Barrel: 4150V Chrome-moly vanadium steel, chambered in 5.56 NATO, with a 1:7 twist, M4 barrel extension, and a mid-length gas system. The A2-style profile barrel is nitride treated for accuracy and durability. Barrel is finished off with an .750" diameter F-marked front sight base with sling swivel, .750" diameter low profile gas block, Magpul rifle-length Olive Drab Green handguards, and an A2 flash hider.

Upper: Forged 7075-T6 A3 AR upper is hard coat anodized black for durability, and M4 feedramp cuts, These upper upper receivers are made for us right here in the USA.

Bolt Carrier Group: For AR15 and M16 rifles and carbines. Bolt is made of shot-peened, Mil-spec Carpenter 158® steel. Gas key is secured with grade 8 fasteners and staked. Bolt carrier is parkerized outside and chrome lined inside. Includes Charging Handle.

Lower Build Kit: Includes Mil-Spec size MOE Stock, MOE Grip , MOE Trigger Guard, Palmetto State Armory Lower Parts Kit, and a 6-position Mil-Spec diameter buffer tube assembly.

Waiting for these to go on sale again...
Bought my Dissipator recently and have enjoyed having the rifle sight radius on a carbine length gun. Seems like an improvement over the original design (assuming you don't need a bayonet...). Mine came with the gas-block incorrectly clocked which impaired function. Got gas block rotated and secure and am very pleased. Would buy another just due to the unique configuration.
