got a beeman spring action rifle was working perfect til i put a scope on it now doesn't have enough wind to push pellet out know anybody local who might fix it 850 516 0527
Is it possible the screws for the scope mount are interfering with the spring?
If it was working before you installed the scope but not after, might be worth removing the scope and seeing if it works again.
I'd do a soapy water test around the sight mount base/screws. Are you loosing pressure there? Are mounting screws too long and obstructing bore/pellet? Pelled show "strike idamage" ? Did you inspect clear the bore? What model? Too many variations to guess. Look at a parts list schematic to see what if any internals were anchored by the iron sight mounting screws. They are pretty simple to dissemble, probably a ytub vid on it or like model internals. Like these:
We ship worldwide - Airgun, Shotgun & Rifle spares, parts and accessories for for Air Arms, BSA, Crosman, Diana, Gamo, Relum, Webley, Weihrauch and more
Not much involved with taking a springer apart. Is it a regular spring or a piston gun? Look on youtube for videos on taking apart that model. Also check http://gatewaytoairguns.org I bet someone there will know exactly what the problem is..
