I picked up a parts gun(spencer) in .44 Russian. someone had blowned the bottom out of the chamber.(bad barrel). after several years I found a new 56-50 barrel and it screwed right into the .44 Russian receiver. the hole in the receiver for the mag. tube wasn't big enough for a 56-50 case to go throught it. I reamed out the receiver and now the 56-50 cases fall through the receiver. I did have to buy a lower block to get a compatable extracter but that does work now. I'm ready to fire the rifle single shot but I'll like get it to feed from the magazine. the bullets jam up coming out of the mag. tube. I need a picture of the upper block of a newer 56-50. that will tell me if I need to grove the top of my firing block(upper block), to let the next round comeout.( I've had several 56-50 spencers and I love them. ) but I'm fresh out of them right now. all I need is a picture, please send a picture to pm861@sbcglobal.net,,ok,l I'm a real old cowboy shooter.
Thanks Pat
