Will a Dragunov stock fit on an AK-74 ??

a 'real' draganov svd stock will not fit on either a stamped or milled ak (the drag is milled).

however. a.t.i., choate and the romanians DO make dragunov STYLED stocks that will fit the ak series. the romain stocks only fit the stamped akm type receiver.

If yes, any idea where to source and how much ??

take-off romy stocks sell for $10-20. i can't remember who had these laminated stocks, but a call to tapco and cdnn might be in order.

choate and a.t.i. polymer versions are available from their websites (no links near me right now) and numerous resellers. the choate is of good quality and sells for about $50-55. the a.t.i. is of lesser quality and sells for about $35-40 at my local gunshows.

Will one of the wire-frame stocks work on the AK-74 and if yes any idea where to source and how much ??

yes, tapco sells the romanian right side-folding wire stock already welded in the open position for the post-ban rifles...about $50, iirc. folding versions that actually fold are available for installation on pre-ban rifles. they will fit any euro stamped akm receiver and can be easily modified to fit chinese stamped akm's.
