Increasing your gun's performance has always been a must, and having an accurate barrel is number one. Proto barrels are made to the highest quality standards and are ultra accurate.
Manufactured with a premium 6061-T6 high grade aluminum and honed to a .690 micro finish.
Straight porting makes the Proto barrel a quiet and accurate addition to your gun.
*NOTE: Because barrels differ only in threads, a single image may be used for multiple barrel thread types. The threads pictured may differ from the actual threads of the barrel. Please order according to the product description, and not by the image of the threads. If you are unsure what type of threading your gun requires, please call us before ordering.
