  1. .308 AR barrels need standards!

    Black Rifles
    I Bought 2ea .308 Winchester barrels for my LR308. Both had issues with being able to simply drop in a mid length hand guard. Returned the 1:10 5R barrel to Brownell's and kept the 16" 1:11 5R rifle from Rainier Arms. However, they both could have been better if they had changed the dimensions...
