i went out the other day with my bar 270 and in the morning with out a scope and i could put a round in the chamber with no problem. then i went out and bought a scope to put it on then went out to the range to sight it in and now i cant pull the receiver back far enough to get a shell in the chamber unless if i pull on it really really hard anyone know what would cause this? would it maybe be a spring or some thing?

Are you sure the bolt isn't hitting the bottom of the scope some place? I can't think of anything else that would cause that. You might need to loosen the screws and slide the scope back a little to clear the bolt. Last resort I would carry the rifle and scope to a gunshop that mounts scopes. You might have to get either a medium or high mount if the scope is a high diameter scope.

its a semi auto and i still cant figure out why its not working i just dont get it because it was working fine before i put the scope on.

figured it out the screws for the scope mount were 2 long.
