I did some swapping of various parts from one to the other and came to the conclusion that the bottom half of my BYF is the cause of the hold open issue while the top half is causing the brass shavings problem. not sure what half is causing the empty brass to get caught between the bolt and the breach

Last problem may be ammo or magazine related.

Does the combination of the two "good" halves work well?

Could be for the ammo; It was maybe 10 year old WWB with newer mec-gar magazines but it only happens with the BYF

The half with the BYF bottom had the same exact issues with the 1918 DWM top

The half with the BYF top and the 1918 bottom didn't have an issue cycling or staying open on the last shot BUT the sear bar tab thing would not **** after each shot so I would have to rack another round to get another shot. I ended up just putting one bullet at a time in it and it held open after every last shot BUT would still dent brass and send shavings everywhere.
