Model: Dissipator style barrel, rifle length gas system paired with 16 inch length.
The rifle length gas system on this 16 inch 223 Wylde chambered barrel allows for a soft shooting configuration and fine tuning to your rifle build. With the longer gas system, the bolt has additional time for pressure to subside, making for a smoother unlocking and less wear on the bolt. The gas port is sized to ensure reliable function when unsuppressed, the same as the original Brownells BRN-605. This gas port also allows for fine adjustment when paired with an adjustable gas block, which is recommended if using in combination with a suppressor. The .625 gas block journal is 1.9 inches long to accomodate a variety of gas block types, including .625 GI style front sight bases.
Ballistic Advantage is manufacturing these to Brownell’s specifications and quality standards, ensuring you get the best barrel possible. Barrel exteriors are coated with the standard phosphate finish, which provides an excellent matte finish, and retains oil extremely well. The most important aspect of the barrel, the bore and chamber, are hard chromed, to prevent corrosion, ease cleaning and prevent long term wear. The button rifled barrels, profiled from 4150 Chrome Moly Vanadium steel, feature a 223 Wylde chamber, that allows them to accommodate 223 Remington and 5.56x45mm NATO ammunition equally well. The 1-8 twist will handle commonly available Full Metal Jacket 55gr loads, all the way up to heavier, premium 77gr bullets. All of these Lightweight Barrels have a .625 gas block journal to correspond with the overall slim profile, preventing your Carbine from becoming front heavy. ½-28 muzzle threads accept common muzzle devices and the M4 feedramps at the opposite end interface perfectly with M4 feedramps in your upper receiver.
