The only thing I did to my 10/22 was to add some peep sights like those on an M1A. I prefer those type of sights over the notch and post. I never heard of bolt buffers for a 10/22 and don't see a need for them. The rifle runs great as is. I would like to add a sling but I don't want to drill into the wood. I would like to do an Appleseed with my 10/22 but its pretty much shot out. I can slide a brush through mine with no problems while I have to push on it to get through my wife's. I'm afraid mine won't be accurate enough for Appleseed.
