Ain’t YouTube great? I view many conflicting statements about upgrades and fixes for the Ruger 10/22. My question concerns the bolt buffer pin. I replaced the steel pin with one that has plastic tube with a steel core. I have seen nylon replacement pins all of which are supposed to keep the aluminum receiver holes from becoming egg shaped. Sounded reasonable but it also eliminated the metal on metal sound. Is egging of the buffer pin holes a problem? Some are saying it not going to happen and save your money. I like it because I did not like the metal on metal sound. I have only had mine a couple of years and do not have that many rounds through it, comments?
