Haven't put any rounds through the barrel yet but it definitely looks good. I have no hesitation this will shoot without a problem.

Have not had a chance to quantify the accuracy but the fit and finish is great. I had a tight timeline to get this project done and the shipping was very fast.

16" .300 Blackout 1x8 Lightweight Nitride Barrel
January 23, 2017
: Brent S
I am extremely impressed with the weight of this barrel considering it's 16". I shopped around for a barrel for better than a month and ended up choosing this one and I'm extremely gladI did. The only one thing I wish I could have found is a 20" barrel, especially a Melanite Nitride coated one.

This has been the 3rd order I have made with MAS Def. Everything I ordered was quickly shipped and was exactly what was ordered. I am very happy with the products that MAS Def. sell and the price thatthey sell them for. A 1st rate company that I have recommended to many friends and I will continue to be a loyal customer.
