Im kind of anal about spare parts and ive got only carbines right now but im thinking about getting a mid length set up ...what parts are not universal between the two systems? barrels and gas tubes are not but what about bolts, bcgs and buffers?
I have had no reliability issues using standard mil spec carbine buffers and springs with a mid-length barrel system. No fancy buffers, springs or adjustable gas blocks needed either. Rifle buffers and springs should be different.
I used an Adams rifle gas-length piston upper with a carbine lower without issues as well. Not sure about the piston upper. Shoots really soft but accurate enough. Figured it might work for a small women or teenager who are learning to shoot something more than a 22. No major issues with reliability, although I never put enough rounds down range at one time to determine MTBF.
