well, you can always expect a difference from firearms assembled during peace-time compared to firearms built specifically for an on going conflict. Even if it's not a "last ditch" rifle. Generally, during war time, manufacturers have to up their quota for the government and won't produce weapons of quite the same caliber as peace-time. This is true of any military items. If Mauser was contracted to arm a standing military in peace time, they'd have to produce... say 200,000 rifles in a couple of years. But, then war breaks out and the nation needs more rifles to arm a growing military. Mauser would then have to produce another 300,000 rifles to arm new recruits in a matter of months, and the quality will suffer, but not by a ton. Last Ditch is where it gets down to "we have to arm EVERYSINGLE CITIZEN!" and they're running out of production members and materials, then the quality takes a pretty big dip.
This is going to be evident in any military and any weapon that you look into. Generally speaking: peace-time rifles will be better built.
