Best barrel on the market by Mbz2020, July 9, 2019

Can’t beat a cold hammer forged dd barrel, these are very well made and hold some incredible accuracy. This is my third dd barrel and I don’t think I’ll buy any others. Highly recommended no matter which size or caliber.

The best I’ve had by Dl, Verified Owner, March 10, 2025

Short of a custom barrel with head-spaced bolt, these are outstanding. Probably one of if not the best drop in barrels around. 55g xm193 doing MOA all day long. What more can you ask for
