- The Best!I purchased this barrel to be used in my MK18 build. I am able to achieve less than 1 MOA groups with this 10.3" barrel! Could not be happier with the barrel. High quality steel with a high quality finish and chrome lining make this an excellent barrel that will surely last a long time.

- Worth every pennyI built my custom SBR with this barrel, it’s been dependable and accurate for thousands of rounds. There’s definitely much cheaper barrels on the market, but you get what you pay for.

- .070" Gas Port is Perfect!!Using the .070" gas port version of this barrel with a pinned low profile gas block, standard auto BCG, JP H2 silent captured spring, and SureFire 556-RC2 suppressor. Perfect reliability! 5.56 ammo ejects at 2:30 o'clock when running the suppressor. Wolf steel case 223 ejects at 4:00 o'clock without the suppressor, and locks back on an empty mag. Nice, soft shooting setup. Couldn't be happier!
