New Pistol Gas Length Description:

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 1:8 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. We are so confident in our Match barrels that we will offer a 100% money back guarantee within 90 days of purchase. If you aren't completely satisfied with the barrel for any reason, return it for a full refund, no questions asked.


We offer a 1:8 twist to accommodate to a wide range of bullet weights. Guaranteed to shoot sub-MOA with match grade ammo.
