Got the book today and if you have one of these rifles it is well worth getting and the price is well worth it. It details the whole stripped gun, which scope rings will work and the 2 types of rails how to strip and clean the whole gun including the bolt. Also covered is what problems may occure and what to do about them. Also has a drawing for the firing pin in case you cannot get one you can have one made. A great little book it is not big but packed full of info on this little 22. (26 pages of print and pictures )Well worth the 6.95 I paid for it. Well reccomended if you have one of these guns. Jim
