My brother and I bought Jim Kibler's SMR in 32 caliber. We had sent inquiries to Jim regarding elongating the holes for the pins holding the stock on but have not had a call back . Also having trouble with the rear sight. The dovetail is very shallow and my sight moved while shooting. We are very impressed with the gun and love that lock ! I am sure Jim is very busy with all his new guns and customer contacts so we are hoping you fellers can give us some suggestions. We are not opposed to installing different sights, we want to hunt squirrels !
