    Excellent barrel, this was an inexpensive barrel but the accuracy is great , built several loads and it runs perfect….adjustable gas block ..about 10 months now and no complaints lots of rounds getting another in reserve…..good job KMT….

    First of all, the 2 barrels I bought here, headspace perfect with PTG Go/No-Go gauges. The 2 barrels 10.5 300 BLK are dimpled and nitride coated. Installed one in a pistol build (the other is a spare barrel for the same build) with a PSA Nickel Boron 2-Stage trigger and Holosun 510C Sight. Using a Garmin Xero C1 Pro Chronograph, I got muzzle velocities averaging 2,250 FPS using Hornady V-max 110 grain by AAC thru this barrel. At 25 yards I got 4x 5-shot groups (20 rounds total) on top of each other!!! Extremely accurate for me!!! Next trip is at a 50 yards range but because this build is a pistol with a “proper” pistol buffer tube (no brace or anything similar), I’m not sure if the Rangers let me shoot a pistol without a brace at 50 Yards. I’ll see what happen but so far this barrel is fantastic!!! For comparison, I got another build with a Faxon Gunner 10.5 300 BLK barrel using Sig Sauer 120 grain solid copper HP and I got same results (i.e., 25 yards I got 4x 5-shot groups on top of each other) in terms of accuracy (different velocities of course!). Last but not least, using a JP Enterprises buffer spring and a H2 buffer, this bad boy cycle perfect every time!!!All in all, I cannot justify anymore spending more money on a “Gucci Barrel”.
