Superb barrel
August 20, 2023
: sean huzell from Fort Lauderdale, FL United States
Barrel is beefy but still lighter than the BA 10.5" I previously owned. Finish is clean and a huge quality of life feature having the dimple for set screw gasblocks.

Swapped out my 10.5, 5.56 for this.
February 17, 2019
: Frank F. from Reno, NV United States
Incredible barrel, can't imagine what your match grade is like. Decided on a barrel that would burn all my powder.
Went to the indoor range to dial it in and it tore tiny one hole 5 shot groupings at 15yds. Can't wait to take it out on the rifle range to break it in..
It would be nice if the military adopts this round for special applications..

My first barrel from MAS defense and will not be the last. Fit perfect with an A upper and functioned flawlessly in testing. As soon as the weather will cooperate will be accuracy testing.

My third barrel from MAS
July 27, 2016
: Brian B
As always, nicely machined and finished. Looks just like the pricier brands. I like Melonite finish on barrels too. Tough and not reflective to keep from giving away your position.
