Bought this barely last month based on the reputation GM has. So far, thus barrel does not disappoint, and I don't think it ever will. Arrived in perfect condition, nice lines/contours. Slid right in my receiver. No rough spots, no burrs, nothing but perfect. Actually just completed my build today and fired it for the first time. Gonna sight in this weekend. If one is looking for a great barrel, this one won't let you down. Thanks GM.

I bought this for my new upper build I really liked the stainless fluted. I finely got it to the range and got it broke in a little only 70 round's, but it shoots great! I was shooting cheap Winchester 55gr and I got them shooting 1/2" at a 100 yards. Then I did a quick cleaning after shooting 60 rounds of cheap stuff I also ran a bore snake every 10 rounds with some solvent and put 10 round of match grade Hornady and I was punching the same hole at a 100 and a 1/4 at 200. These barrels are crazy accurate. I'll definitely buy more.

I purchased this barrel a few months ago for a SPR rifle I built. After a dozen trips to the range, and about 500 rounds through it, this barrel just keeps getting better and better. I can average .5 MOA with quality ammo and with handloads its even better. The fit and finish is simply amazing and I will not hesitate to buy another for my next build.

with under 200 rounds thru it I got one 5 shot group at 200 yards just under an inch with 60 gr. Hornady SP's.At 300 yards the same load went just under 2 inches.But I knew what to expect as I have 2 drop in TC Muzzle loader barrels, .54 and .50,Great shooters with round balls at 100. Two .45/70 BPCR barrels and 3 10/22 barrels all from Green Mountain All the 10/22's will shoot under one MOA at 200. 300 for the 45/70's and the AR-15 if I do my part.

Very good barrel, accurate with 55gr federal bulk pack ammo. Love the satin finish, my only regret is that I didn't buy more on Cyber Monday!
