I have quite a number of Mossberg .22's, among them a number of 151M's and a 151K. They are nice rifles, but then I like most of the old Mossies. These old Mossies are becoming quite collectible with a number of people jumping on the band wagon. Therefore, pricess are starting to increase. Not near Winchester status but still going up. That being said you can still find a bargain. I bought a 151K last year from a large gun auction in my area. I couldn't attend so I bought it sight unseen via proxy bid. I had a maximum of $165.00 on it and I got it for $130.00. I sure wouldn't sell it for that. When I picked it up I was very surprised as it is in very good to excellent original condition. The next time you can't touch one for under $175.00, so you never know. It just depends on any given day who in your area is looking for one. They often don't go as high as the 151M's as there is no provision for a peep sight on the 151K, Therefore you are limited to open sights unless you scope it. But the 151K is a little rare being made only 1950-51. If you do find one ,try and get one with the sights still on it. The price for Mossberg sights, swivels, etc. etc. are going through the roof. Many people are selling the sights seperately and then trying to get full price for the rifle. Good luck in your search. You have to just keep watching.
