O-rings problems...

[Ghetto]

hey whats up, rookie question here, so forgive my ignorance. Anyway one of my mags was leaking down the barrel. So I took my gun apart and the power tube was starting to back out ( not the brass piece on the tip but the whole assembly ). So I un-screwed it totally and the o-ring was cut. My Question is this, is that o-ring included in a parts kit? thanks

If your powertube unscrewed, you need to send your Mag to the factory to be repaired.

Call and get a repair authorization before you send it in.
