GOG Smart Parts XL Freak Barrel Front - Gloss Black Length:16" and an expansion chamberFaster threads Front and Back Fast front to back threading Because the Freak XL is its own system, GOG was able to utilize a course thread between the barrel front and barrel back. This threading makes taking the barrel apart or putting it together faster then ever. The courser thread is also easier to keep clean, and is tougher to cross thread if you do make a mistake with alignment.
