Product description

We understand the importance of equipping your AR15 with a durable and long-lasting barrel, one that will ensure you do not miss your target when taking aim. We designed our DSG utility-grade 11.5” barrel using 4150 chrome moly vanadium steel to prevent corrosion and coated both the barrel and barrel extension with QPQ to ensure longevity.

Since you will be carrying your rifle with you most of the time, we settled on giving our barrel a government profile and flat muzzle crown, both improve shooting precision and accuracy. In addition to this, our barrel features a 5.56mm chamber to reduce pressure, 1:7 twist rate to increase bullet stabilization, and .750” gas block seat to prevent bending, reduce overheating, and improve equilibrium. 

We have also included a 1/2x28 muzzle threads and M4 feed ramps. You will find our DSG utility-grade 11.5” barrel with a carbine gas system an affordable purchase due to us not adding a dimple to the barrel and using the button rifling method to create it. 

If you want, you can easily make your barrel dimpled by adding a dimple at home. Even though we used methods that would decrease our manufacturing costs and cut our lead times in half, we have not compromised on quality.
