Guest Airsoft J2 Posted February 20, 2017 Share Posted February 20, 2017 I've just picked up my 12 year old Umarex P99 (fixed slide) gas pistol for the first time in a long time and have found (perhaps not unreasonably) that one of the magazines is very leaky and the other is losing pressure more gradually. Unfortunately, I can't find them for sale any more so I'm hoping to fix it rather than replace the pistol - any suggestions beyond replacing and greasing all of the seals?

Supporters Rock-climby-Dave Posted February 20, 2017 Supporters Share Posted February 20, 2017 all the valves are reparable with time and the right O-rings. good starting place is a £4-5 bottle of abbey maintenance gas. Usually sorts out slight leaks. Link to comment Share on other sites More sharing options...
Guest Airsoft J2 Posted March 11, 2017 Share Posted March 11, 2017 Cheers Dave, sorry for the tardy response. I'll start with some maintenance gas and lube and see where I get to. Link to comment Share on other sites More sharing options...
