A couple of the M50s I have on hand have had the stocks slimmed down a bit. Probably didn't really lose much weight but they felt lighter to me. I have one that is all original as well an it feels rather clubby to me. Seems heavier too. Probably all in how it feels in the hands I guess.

Our forefathers did not politely protest the British.They did not vote them out of office, nor did they impeach the king,march on the capitol or ask permission for their rights. ----------------They just shot them.
