Hello fellow airgunners... I have a Umarex 1250 Pcp. I went to fill yesterday and the cylinder wouldn't hold air. How does one open the cylinder up and replace oring? Thanks
Air cylinder on pcp pistol wont air up. Its on a pcp pistol where the cylinder is removed to fill. Do I need to unscrew the end and replace an oring ? The end cap of cylinder has 2 holes. How do I remove the cap? Thx ES
