I gotta buy a thesaurus - I keep giving the wrong impression
. I am *not* parting with the Buckmark (!), Emoto, just looking for another .22 to add to the stable but one that breaks down without tools.
DOA and Red_Beard, I'd always heard a lot of griping about dis-/re-assembly but that link makes it look pretty damned straightforward to me. If/when I get serious about buying, I think I'll go to a "toy store" when it's slow and ask the guy if I can just do it then and there. Find out first-hand once and for all.
Anothergene, it *is* the front (muzzle-end) screw and it's a hex-head. I tried removing the rear screw and pivoting on the front but having to lift over the recoil spring plug was starting to put a slight bend in the sight rail. I'll probably end up buying a new rail when I order the screw, just to keep everything plumb. Should probably buy a bunch of stuff while I'm at it, too, or I'll spend $7 shipping for a $2 screw! Cheap bastard that I am....
