I'm pretty sure my peepsighted HW30S has a broken spring. I can hear a rattle when the cocking arm is open plus it won't hit the side of a barn at a very slow speed, as reported earlier.When the piston seal arrives, I'll take her down and do what's necessary. Assuming there is a broken spring, how do I get the top hat and guide off of an ARH spring and put them on another spring?
Please post your findings when you get into the gun.
