7.5" 300 BLACKOUT 1x7 4150 CrMoV MELONITE NITRIDE AR-15 BARREL

Great service with MAS Defence. Email updates, a real person on the phone if you have questions, accurate tracking, and the barrel looks perfect. I'm happy to see MAS continue to update and add to their product line.

5 of 5 Blackout Pistol Barrel a must January 20, 2022
: DENNIS L from Cumming, GA United States  
Ordered a 7.5" Blackout barrel for a pistol build.  Not only did it arrive fast, but fit exactly as I wanted, and performs as expected.  Great finish.  Seamless fit with my gas block.  If you're planning a build, MAS Defense parts won't let you down.

Haven't built the 300BLK yet, but MAS had a helluva good deal and fast shipping like usual! Previous barrels all performed well without a hitch!
