Product description

Our DSG utility-grade 8” is worth your money! You will not regret your purchase once you hear about all the incredible features of our product. For this barrel, we have designed a 300 blackout barrel to increase safety while shooting made from 4150 chrome moly vanadium steel to reduce corrosion resistant.

Since the 300 blackout barrel has a slightly longer neck, it is a great choice for hunters. If you are hunting with the 300 blackout barrel, the preferred twist rate for it is 1:7, which our product has. To ensure your bullet hits the target, we have included a flat muzzle crown for improved accuracy.

Our barrel, weighing 18 oz., also features a .750” gas block seat to reduce overheating, prevent bending, and increase stability. For this barrel, we opted for a heavy profile for precision shooting. Our utility-grade barrel and its barrel extension has received QPQ coating to increase its lifespan. It also features a pistol-length gas system.

We have used the button rifling method and have not added the dimple to our barrel because we wanted to shorten lead times and manufacturing and provide you with an affordable product in return. Our barrel also features M4 feed ramps and 5/8x24 muzzle threads.
