Subs/Supers all around great barrel. May 23, 2015 : William D   Purchased this for an SBR build and couldn't be happier. With an ST-T1 and heavy extraction spring with O-ring this barrel will easily cycle from 120-220 grain 300 blk rounds. First had issues with extractions but extraction spring cleared it right up! Great accuracy, with 4x scope at 100 yards was shooting 1/2" groups and less depending on rounds. Was this review helpful to you?

Great barrel January 23, 2015 : Frank F   Just received my 8.5" 300 BLK barrel tod and it looks great. Need a few more parts before I can complete the build but I can see the quality and craftsmanship in the barrel. Feels solid, can't wait to get to assembly! Thank you Mas Defense for a great value.

Looks great! November 17, 2014 : Tyler W   Look and finish are great. Functions perfect, not fully broke-in yet but accuracy seems great so far. I was worried about a pistol functioning well with this short of a barrel but it seems to be very reliable. Was this review helpful to you?

8.5 300 BLK barrel June 20, 2014 : Steven B   Fast shipping, great packaging and the barrel fit right in my upper receiver. Getting 2.8 inch groups at 100 yards with BUIS on a 10 rail using 147gr. factory reloads! Awesome barrel for the money. Was this review helpful to you?

No complaints. May 28, 2014 : Daniel M   This barrel is probably the best looking barrel for the money. I've shopped all around and this one was the cheapest and still looks to be pretty sturdy. Haven't yet fitted it to my Alpha Billet Upper, but it looks solid. Was this review helpful to you?

Awesome product, Awesome seller May 16, 2014 : Shane O   I had been waiting for this barrel to come back in stock for a while, when it did, I jumped on it. My transaction with Mas Defense was perfect, shipping was much quicker than I expected and I receivedexactly what I ordered. The fit and finish on the barrel appears to be perfect, I am still waiting on a few more parts to complete my build, but I do not anticipate any issues to arise. Was this review helpful to you?
