I just bought my friends 10-22 takedown. it's my first rifle, I have a pistol and shotgun. the purpose is mainly for plinking at the local metallic range , 50 yard -100 yard targets and a BUGOUT gun, something both my wife and I can shoot. I'm over welcomed with the accessories/upgrades. I don't want to get 1911 crazy, been there done that, I have purchased an auto bolt release. but what is considered "essential" upgrades? Extended bolt? Red dot? rail barrel clamp? trigger group?
