The 16” Dissipator barrel is designed to mount rifle length A-2 hand guards, which gives you a greater range of control over your CAR length rifle. It also has the added benefit of having a full site radius, which means a greater level of accuracy! It’s mounted on an aircraft quality aluminum Mil-Spec upper, with Flat-top upper Receiver. This upper is the real dissipator, other manufacturers reduce a 20" barrel and gas system to 16" which causes the gas system to become unreliable. We use the standard 16" barrel and gas system with a low profile gas block under the handguard. We then attatch a front sight tower for your sights and handguards to make our dissipator the most reliable dissipator you can buy.
