FOR A LIMITED TIME - EVERY MK12 BARREL PURCHASE INCLUDES AN OPS INC BRAKE AND COLLAR!
Due to the MK12's extended .750" profile forward of the gas block, significant marring of any paint/Cerakote/finish will occur from installation/removal of the gas block (whether pinned or set screw), no matter the finish (as the original MK12's were.)
PINNED AND CERAKOTED OPTION AVAILABLE HERE

*** We recommend gunsmith installation for all of our parts. We cannot warranty items damaged by improper installation.
Good profile and notch for the gas block. Not perfect clone profile, but more functional. Easy hits at 400 on ten inch plate.
The barrel is great, but think the shining point with this experience is the customer service. Hands down the best company I've ever dealt with.
I ordered this barrel with high expectations. As always it did not let me down. The quality was top knotch the fit and finish was everything you want from a high level barrel. Thank you for your amazing workmanship
First off...Centurion Arms is a great company. Very helpful and quick to respond on any questions I had. There was an item that was misplaced during shipping and I emailed them in regards to that. Corrie responded within 15 minutes apologizing and 10 minutes after that I received tracking information and the part was delivered on my door step the next day on a Saturday.
No for the barrel itself. It is amazing. Extremely tight fit into the upper receiver. We had to get a soft hammer and tap it into place. I do all my own hand loads, especially for the 77 grain projectiles. Out of several tests loads, I saw groups ranging from 1/2", 7/16", and 3/8" at 100 yards with different load calculations and projectile manufactures. As Bill said in a previous review...it does not get better then that.
I highly recommend this barrel in any MK12 build. Amazing barrel and amazing company. I look forward to ordering more products from Centurion Arms.
Monty and his wife, Corrie, are the real deal. I couldnt write enough to convey their integrity to you here but when you spend money with Centurion rest assured that your money is truly going to people who deserve it. Simply the best people Ive had the distinct pleasure of doing business with.
My Mk12 barrel shoots 4 rounds in a 3/8" cluster at 100 meters on its first trip to my range. Folks, now it just dont get much better than that. The machining of the chamber is artfully done as is the outside. Its very clean and the Cerakote well executed. I also had the FSB pinned and also opted for the Ops Inc and to say Im pleased is an understatement. Its perfection and thats about all I can really say.
Centurion Arms deserves our support.
