Re: AR-15’s
I wouldn’t be too concerned, practice a bit more and you’ll be right in there. Use quality ammo when you can and make sure that you’re matching the bullet weight to the barrel twist. The Ruger has a right hand twist of 1 rotation in 9 inches, meaning that it is optimized for bullets in the 60-64 grain weight range. It will probably do fine with 55 grainers and even 69 grainers, but it will not stabilize bullets over 70 grains. Buy whatever ammo you can afford and shoot, shoot, shoot! Keep the BCG wet with lube and keep us updated.
