No problem, if you don't like the master mount you could always take it off.

Just noticed the thread here. To the O.P. I do have a Bulgarian 74 patterned side rail if you still are looking for one. And I may be able to help install it time and location dependent. If your interested, drop me a pm.
FHUGETABOUDIT!!!
Side rail is pretty easy to put on and will be a better solution in the end than the master mount.
Remove rear trunnion rivet, re-rivet rail to rear trunnion using existing rivet hole, align rail with receiver top rail, drill two new holes and rivet. Hour job at best.
