Features

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 Carbine-length gas system. This M4 style profile barrel is nitride treated for accuracy and durability.  Barrel is finished off with a pinned F-marked front sight post 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.  These uppers are made for us right here in the USA by a mil-spec manufacturer.

Each upper is assembled to order with care, and test fired. 

Bolt carrier group and charging handle not included.
