I am pretty new to precision rifle shooting took my first class with my savage 10fcp 308 bolt gun and got hooked i talked to someone that recommended upgrading one of my ARs to an 18inch barrel and throwing a scope on it to train with since it would be cheaper ammo wise instead of buying a whole new bolt gun. Long story short i ordered a wilson combat urban sniper barrel instead of going with a white oak because im impatient it showed up in the mail today and to my surprise it didn't have a threaded muzzle it is crowned can someone give me a rundown on crowned vs a brake should i just run it? I doubt wilson combat will let me return it considering it was my mistake and i opted to have it coated.
