What is the going price for a preban Galil Magnum Research AR model #361 in 97% to 98% grade? And..what is the going price for a first version (Magnum Research I think) Galil AR15 mag adapter that uses a cross pin to block the AK type magazine release from allowing the magazine adaptor to "accidentally" be released Worth? And finally.. what  are great shape Israel Military Galil 35rd steel and aluminum mags worth?

Yo post be crowded excess info.
I don't think I would even bother to price in  that "first-version-Magnum-Research-I-think
Galil-AR15-mag-adapter-that-uses-a-cross-pin-to-block-the-AK-type-magazine-release-from-allowing-the-magazine-adaptor-to-"accidently"-be-released "thingy."
Are the 35 round mags a bottom and top welded together ?
O. Franklin, your looking at a "Galil" - the finest AK made to date.  I personally wouldn't use a mag adapter on a bet.  (Be certain to find out if there's an "S" stamped on the receiver.)
If you'll come back with "S" or no "S", are the mags welded - yes or no and how many mags I can give you a guesstimate.
Or maybe this will help some,  the 97% Galil with no "S" stamp and a couple of decent mags is worth about $2200 - $2300.
