They tend to go for around $300, give or take $50 depending on the condition, assuming the magazine is there.
They fire from an open bolt, so they can be a bit "twitchy". Getting used to that twitch or shudder when the bolt releases probably made me a better shot. Trigger is a 2-stage, like a military trigger. Very simple mechanism, no firing pin, extractor or ejector. Firing pin is a bar milled across the bolt face. That plus the open bolt means you'll almost never have a misfire, and when you do you can be sure it's a dud. I use mine to fire off all the misfires from my other .22's.
Magazines are hard to find and easy to lose. If you accidentally hit the mag release ( easy to do ) it drops right out. Very nicely balanced and lightweight. It will never make a target rifle, again because of the open bolt.
