Model 121 Breech Block

Post by stwtorpedo »

A customer actually lost his Remington 121 breech block. I located a new complete assembly. When I attempt to install it, the action does not want to close and lock. The upper rear edge of the heading lug atop the breech block does not quite break over the rear edge of the locking mortise in the roof of the receiver (0.008 to 0.010" interference). It appears headspace would be good if the breech block would go fully into battery. Remington and others have been no help. My guess is that the breech block is manufactured slightly oversize for correct fitting. I do not know if the block is through hardened or case. Would anyone have know the proper method to fit the breech block to this receiver? Thanks much and best regards ...
