KWA USP gas mag inlet nozzle plugged by sand
Hello folks, need a bit of advice here.
During a game I accidentally dropped my ups mag on a sand-padded floor. I cleaned all the nozzle and valve areas but when I try to fill it with propane via an adaptor, the gas wouldn't go in. Tried to fill my other mag with it and I had no problem, so it's not the propane nor the adaptor. Seems like the inlet nozzle is plugged by some fine sand. Any suggestion on fixing the problem? Thanks in advance
