Many have asked us to build a barrel with the same workmanship as our UltraMatch barrels while keeping it more affordable. We are able to reach our goal by sourcing a very high end barrel blank at an affordable price. We start off using a high precision match blank in 1:7.5 twist, machine it to the highest quality and matched with our limited-life time warranty, you have a barrel that is the best value, hands down, in the industry. 

Guarantee sub-MOA with factory match ammunition.
