Hello. I have a 10/22 that will not cycle reliably. I bought it from a guy about five years ago. He could not get it to run right so he sold it to me really cheat and I figured why not for what I got it for. After I got it I got tired of messing with it and moved on to other firearms. With my son getting older and ammo prices rising I would like to get her running right. It will run the CCI hot stuff pretty well but will not run the bulk stuff. I cant make it through 10rnds without 3-4 jams, or more. I have no idea on the internals, i.e. springs and what have you that he might have tried to “upgrade”. I already did the usual detail cleaning and nothing changed. The only thing I can feel that seems off is when racking the bolt the hammer return spring seems to have a lot of resistance for a .22? It does have a silly tacticool style stock on it but I wouldn’t think that would have any effect on reliability. I appreciate your time and help.
