Does anyone have any experience with the Mid America Stevens 44 1/2 rifles?   
I was wondering how they compared to the CPA.   

Is it the same size as the original or expanded to allow for 45/70 rim size.

How was their quality compared to a CPA?

I've got one of his rifles about 10 years ago. 

It was supposed to be a 2 barrel rig, .22lr & 32-40 with 2 blocks and extractors.  The sight base on the rimfire barrel were out of line, looked like they had been drilled on a drill press.  The 32-40 barrel had about 1/2" of throat bored out in front of the chamber.  After a year of trying to get him to make the rifle right as he promised, I sent the rig to someone else who set the barrel back and cut a new chamber.  I put a longer sight base on the .22 bbl and drilled another hole to cover up the misplaced sight base hole.

I wouldn't buy anything from him again unless I had it in my hand first and was completely satisfied before I handed him a dime.  I don't think his intentions are bad but ability to follow through and take care of business are way below par.
