I just got back from zeroing my rifle at the range. I'm still in the break in phase but as I kept shooting my groups got smaller. Only gave 4 stars because I have only gone out once with this barrel. But everything from the quick delivery, the great packaging of the barrel and the overall quality of the was top notch. I'm a happy customer.

AFTER UNPACKING THIS BARREL I WAS PLESANTLY SURPRISED AT HOW WELL THIS BARREL LOOKED AND FELT. THE CROME LINED BORE AND CHAMBER WERE SPOTLESS AND SMOOTH AS A BABIES (YOU KNOW WHAT). THE FIT TO MY UPPER IS TIGHT AND SHUR WITH ONLY MINOR EFFORT TO INSTAL. THE BLACK OUTER FINISH IS FLAWLESS AND WELL DONE, THE EXTENSION AND FEED RAMPS COME COATED FOR DURABILITY. I HAVEN'T TAKEN IT TO THE RANGE YET SO THAT IS THE ONLY REASON I DIDN'T GIVE IT 5 STARS BUT IF IT SHOOTS AS NICE AS IT LOOKS I WILL UPGRADE THE RATING TO 5.

Hopefully, without being too long winded, I will just say that this is a superb barrel, especially for the price point. Since these were on sale, during the purchase of a 16" mid-length AR barrel from Green Mountain, I decided to pick up a couple of these too. I had enough spare parts to build one upper with one of these barrels. The upper with this barrel shot very well with no failures of any kind. My only regret about this barrel is I wished I had bought more.

i ordered 2 of these barrels because they are on sale i have not shot them yet as the builds are not complete but if they are anything like your other 16 inch barrels i expect the results will be the same packaging was done with care and the finish is flawless.. the quality of barrel for what you pay is exceptional this is my third build with your product and all i can say is perfection... well done green mountain
