Radical Firearms barrel


This is one burly barrel, looks like it's gonna work great on my Bushmaster build. No dings, no flaws, dimpled for gas block, and one heavy duty looking piece of equipment. Great price at 100 bucks too. Haven't shot it yet is only reason it got 4 instead of 5 stars from me but will update that when it's complete. So far this is a great purchase to me, quality product, great price. Can't ask for more then that

price was to good


I got this barrel to build a 450 bushmaster just getting around to building it and looking at the specs the carbine length gas tube is not what my barrel is calling for, mid length gas tube is what the one I've calling for but it should work good and can't wait to get this out this deer season
