The wife and I were plundering through some local yard sales the other day. I found a 22 rifle single shor 22 Remington Target master 510-x pretty little gun clean and not beat up. Lady said it belonged to her son (grown) I like 22's I own several so I bought it cheeeaaap! Have I got anything much . Please talk to me I probably shouldnt say but I gave a whopping 20 bucks. Tell me what its worth if anything. Oh yeah it shoots good (better than me). Thanks fella(folks)

Nice find! 510 x was produced from 1940-1962. The going rate seems to be $100-200. If it was a smoothbore it would bring a lot more money.

I think the 510X was made from 62-68 there should be a date code on the left side of the barrel in front of the reciever. Depending on condition, I would guess it to be worth a couple of hundred bucks in our area. Nice find
