Product description

We have designed the utility-grade 16” 5.56mm barrel, weighing 28 oz., following stringent manufacturing techniques to ensure optimal performance. To provide you with a long-lasting barrel and barrel extension, we have coated them with QPQ coating and used durable and strong 4150 chrome moly vanadium steel to increase corrosion resistance. 

The government profile barrel, made for the AR15, offers greater thickness — .750” from the gas block — to prevent bending, reduce overheating, and increase stability. To ensure accuracy in the field, the barrel features a flat muzzle crown. 

Its 5.56 chamber lowers the pressure and its 1:7 twist rate stabilizes your bullets when you fire your weapon. Other notable features of our DSG utility-grade barrel and barrel extension include M4 feed ramps, button rifled, and 1/2x28 muzzle threads. 

We would like to point out that we have not added the dimple to our barrel because it would break through the corrosion resistant coating. If you want to add the dimple to your barrel, you can do it easily at home. Another reason we did not add the dimple is that it increases lead times and manufacturing costs, which would result in higher costs for you. We want to provide you with an affordable option for your AR15 rifle.
