Our DSG duty-grade barrel, weighing 1.25 pounds, will complement your AR15 rifle. We have taken measures to ensure quality of our barrels are up to the mark by using the best materials to design it and putting it through several tests like the HP and MPI.

We strive to provide you with a durable and reliable product. We have coated our barrel with QPQ and coated its barrel extension with nickel boron coating to increase corrosion resistance. To further increase the lifespan of the barrel, we designed it using 4150 chrome moly vanadium steel. Its .750 gas block seat prevents bending, reduces overheating, and increases stability.

Its 1:7 twist rate adds to the products stability by stabilizing the bullets when they exit the rifle. Other features part of our barrel is M4 feed ramps, carbine-length system, 1/2x28 muzzle threads, and button rifled. Improving the performance and functionality of the weapon is the barrel’s 5.56 chamber and 11 degree recessed target crown.

Our barrel also features a government profile, making it easier to carry around with you, as it is lightweight. If you are searching for a barrel for your AR15, consider the DSG duty-grade barrel and reap in the benefits you get with it.
