Amazing deal on a high quality barrel. With hand loads I get 1 inch MOA at 100 yards all day. Can't recommend this barrel enough.


Excellent price on an outstanding gun barrel. Fit and finish looks nicely done. Barrel mounted to upper easily, as expected. For a 1in7, 12.5" barrel accuracy with 55gr loads has been just outstanding and way above my expectations. I have not ran it head to head yet with my 16" Wylde build yet but this barrel appears to be just as accurate. As unbelievable as this sounds this barrel consistently holds sub .5MOA groups at 50yds and sub MOA groups at 100yds with a 2MOA red dot sight off the shooting bench with front and rear bags. Tom's Tactical was easy to do business with and had the best price I could find.


I have a 14.5" and this 12.5" barrel. To my surprise, this 12 incher shoots more accurately. This is based on a 50/100/150 meter reference. Have not shot further yet, but I'll try 250 meters max. At further distances it's more logical to use a scope or quality iron sights. This shipped pretty quickly (received in 5th after order placed), considering the high volume of sales. They will responded to my email quickly as well. Buy with confidence.
