Will Fit G&P WOC Series (WA system)
Completely CNC machined out of a single Aluminum billet, the body of this Pro-Win magazine is for the hardcore skirmisher's GBBR. With a single-piece rock solid housing, and incredibly robust metal components, it could well be the toughest Airsoft magazine ever made. But the most important feature is the roller ball feature which allows for VERY smooth and reliable blowback in a WA system.
The version 2 magazine has a roller wheel on the valve lock lever to ensure even smoother and more reliable cycling of the bolt and like WA and Bomber mags the fill valve is on the back rather than the bottom, to minimize fouling during skirmishing and maintain a realistic look when the mag is in the gun. Like the real steel it is gun metal grey rather than jet black and has a decent weight to it which forces you to handle it more realistically.
Special Note for Inokatsu M4 Owners
If you intend to use this magazine with the Inokatsu M4, we recommend you also purchase the ProWin Magazine Lip Gas Seal and Reinforced Hammer Spring for Inokatsu (Pack of 5) [product code PW-GS-INO5-S]. The reason is because the Inokatsu M4's factory hammer spring is sometimes not stiff enough to strike open the valve on this ProWin gas magazine. Additionally, the custom shaped gas lips are optimized for the Inokatsu M4.
