Cybergun FN Herstal Licensed Magazine For VFC FNX-45 Gas Blowback Pistols (Color: Tan)

"I own 3 of these mags, and I have to say they have held up great. They retain a great deal of gas and I love that the injector port is on the back of the mag.

"I've had this gun for a few days, didn't get to run it in a match but ran about ten magazines thru it. As of now I have not encountered one problem at all. Has insane gas efficency for green gas. Works better with propane but make sure ur lubed. No issues at all

"Exactly what it says it is, a spare magazine for the FNX-45 Tactical, nothing more, nothing less. Note: These magazines have the fill valve in the back, so don't worry about cracking it during a tactical reload!

"Bought two of these with the Fnx I ordered. One works fine and is great, but the other doesn't click into the gun :( I'll have to send it back to get a new one, but otherwise, the mag design is pretty good. Beefy, holds a good amount of rounds, and holds tons of gas.

"Don't get me wrong. The fnx is a superb pistol and I've been using it for nearly a year now and I love it. That said these mags have a pretty serious design flaw. For whatever reason, the on the bottom of these magazines there is a removable cap that exposes the gas chamber. This is sealed with 3 screws and an odd shaped gasket. This gasket by it's shape alone is destined to fail. NEVER REMOVE this cap unless you absolutely have to. If you do you'll never get that gasket to sit properly again and the mag will leak bigtime. Plumbers tape will help re seal the mag when it starts leaking but you need to get creative with it. Tape up the cap very well, screw it back on, and then run tape across the seam where the cap meets the housing. I've done this to two mags now with relative success. Good luck.

"These are horrible. Half of them leak from the bottom seal (under buttplate). The gasket has to conform to a very weird shape and is crudely pressed kinked during assembly resulting in leaks.

Examining the gasket itself it appears to be oversized to begin with which is probably why it gets assembled wrong. It is also hair thin and pre molded to shape. basically very tight tolerance fit, and beyond their quality control. for the price and complexity of that joint, you would figure they would have worked it out.... but again, just vfc things.

just vfc things. throw 40$ a few times in a hole and hope a few of them miss the abyss. that's what buying these mags is like. I had 1 out of 3 so far that aren't leaking. nice odds!
