AR-15/10

We use X-Caliber premium match grade barrels for our Custom Barrels. These made-to-order barrels are among the highest quality and most accurate barrels available in the country. We default to the best/most standard rifling twist rate and muzzle thread size for your barrel length and chambering, but if you want to specify these features please add that in the "Customer Notes" field at the end of the checkout process and we'll get it done!
