This barrel was an excellent choice to have pinned and welded. After getting it zeroed its showing great accuracy. This is my second GMRBC barrel and would absolutely buy a third. The attention to detail is right in line with barrels of twice the price or more.

Incredible barrel, just what I was hoping for. zeroed it this weekend, worked perfectly. Gas hole comes pre-drilled and appears to function perfectly, no issues. Sometimes you pay for quality in life, this barrel is quality.

The product looks great, it's perfect for my M4 project. Can't wait to finish it and take it to the range. Customer service was phenomenal. I will definately buy my next barrel here again. Thank you guys.

So far i have fired 350 rounds from this barrel have of which where tula .223 55g ammo; the other half being FED .223 and XM855. If any of this information has merit to anyone hear you go. This will be my second buy from GM; first was an 18" SS barrel. I cant reiterate how happy iam with them. I bought a cheap radical arms barrel once and will never look back ever since i started buying from this company, I even get a thank you letter with a sticker weeks after i get my item.
Anyways check out the pics for yourself.

Decided to build my first AR and found Green Mountain just by chance. Glad I did. Great barrel for the price. I will definitely be purchasing another barrel from Green Mountain for my next build.
