I have a "fifth model" Burnside carbine. The front bottom portion of
the frame, where the breech pivots, has a very small amount of rotational
movement (horizontal axis). It does not seem to be an issue, but does anyone
know how this part of the frame is attached? Can it be tightened readily? It looks
like it was attached and then the front of the receiver machined. The patent drawings
I've seen do not show this detail. I first thought it was retained by the front end of
the saddle bar but am uncertain.
Regards,
Bill
