Customer Reviews
Given the popularity of our Gorilla Machining of barrels we’ve decided to release info. We start with top grade domestically sourced 4150 CrMoV Steel which is then drilled, reamed, button rifled, profiled and chambered in accordance with SAAMI Specifications. These barrels go through a battery of quality assurance checks each step of the way ensuring a remarkably consistent product every time. They are then finished with one of the nicest QPQ Nitride treatments you’ll find on an AR-Barrel. The end result is a barrel with deadly accuracy and rock solid reliability.

Before purchasing my 7.5 inch 300 blk out barrel I emailed Gorilla Machining and asked if the barrel was dimpled for the set screw on the low profile gas block and was told that this barrel was dimpled for that. Ordered the barrel and when I received the barrel it was in fact not dimpled. The fact that the barrel is not dimpled would not have negated my purchase just wish I was told the truth about this product. Other than that oversight the barrel is pretty nice, fit very snug in my upper receiver and appears to be good to go.
