Great BarrelReview by Jonathon
Bought this For my AR 308 build. I have a Nikon prostaff 5 3.5-14x40 scope and was shooting some Hornady American Whitetail 150Gr InterLock. held a 1-1.5 inch group. It would've been better if i wasn't using a factory milspec trigger which caused me to pull a couple shots. I have ordered a 3.5Lb CMC single stage drop-in to replace it, so i should be able to hold 1" or less. (Posted on 3/10/2015)
