Been very pleased with this barrel. It has been very accurate and precise so far at distances of 50 and 100 yards. My groups have been small and outliers are usually due to my error not the barrel. The Carbine length makes this barrel nice to put on a hunting build as it makes for a accurate rifle that is still small enough to make it easy to carry through the woods, and maneuver around a stand or blind.

I purchased this barrel, shimmed and green loctited. Used BCM bolt. Barrel is overpasseds. Haven't found factory load with acceptable grouping. Reloads with lil gun and 180 pp no go. Brass looked horrible. Added heavy buffer and heavy spring. H110 and imr 4227 show very good accuracy. Accuracy with reloads sub MOA. Knew what I was getting into. Pleased with purchased, just not overwhelmed.

The barrel itself is perfect. Very accurate. It being a 350 legend, I cannot get it to cycle reliably. No its not the gas block or gas tube. No its not the magazine. No its not "bad ammo". No its not the bolt carrier group. The 350 legend straight wall cartridge jams on the feed ramps. I tried different gunsmiths with no luck. It appears the feed ramps need to be taken down more. I reached out to CMMG with no luck either. Sounds like I am stuck with the barrel so it is going to get filed down real good and I'll see what happens then. I cant blame Optics Planet because they just sold it to me. I blame the cartridge…
