I see a lot of people switching back to pump, but i want to go the other way, does anyone know how to get the stock pump arm off a 1999 sniper 2 without cutting the arm off and drilling the stainless out? That's all i can think of to do.
Semi auto cockers use different pump arms than what's on the pump handle. You will need to buy one. Don't hack apart what's on there because it won't fit.
I have no idea why you'd do this though, sounds like a real waste of a nice gun. Just pick up a cocker that's already semi for $100-$150 and keep that one a pump. Or get an autotrigger kit so you can shoot the pump fast enough to keep up with semis.
