A few months ago I bought a ruger 10/22. with the wooden factory stock.It worked perfect.I really liked the look of the Butler Creek folding stock,..so I purchased one at the local gun shop.So I took the ruger out shooting a couple days ago and it worked like crap!!I figured it was dirty so I cleaned what tiny bit of dirt there was.Put it back together and for 40 rounds or so ,it was fine ,then it screwed up again.Bang bang nothing,recock,bang recock bang nothing ,recock,bang,nothing.I no longer had a semi auto,I had to #### it every time I fired.Took the ruger and the B.C stock back to the gun store.The gun smith found the problem imediatly.The reciever is held together with floating pins.It takes little efort to push them out.The triger pin had started to push out of the side causing the problem.The origonal stock fits nice and tight,keeping the pins from trying to push out.The B.C stock is alot wider and sloppier built and the pins are not held in place.Sure,you could shim up the sides,but why bother.I just put the factory stock back on ,and it works exellent again. So if you fide your 10/22 working poorly,it just might be your fancy new stock giving you greif. Any one else run into this problem?
