I Finally got to test shoot this barrel, It is way more accurate than I am. Very accurate right out of the box. Green Mountain is my go to Barrel!

Purchased this for my wife's build last year, after some teething problems with the buffer and spring got it working perfectly, the gun weight's about 6lb with scope and bipod, consistently shoots 1/2 moa @ 100 yards, even thought it is fluted accuracy doesn't change. PS: whish they had one in 6.5 Grendel.

I purchase GM barrels and will continue to do so. Great customer service and a quick shipper. Wish they would produce AR308 barrels.
