I'd like to know the difference between 308 and 8 mm top covers. I want to know how the NOS mg1 top covers differ from the MG3 top cover. Here's what I do know.
1. WW2 top covers are used as is and a spacer is placed in the feed tray for 308.
2. The MG1 top cover has a smaller opening and the 308 feed tray is also shorter to match the top cover. It also has a dohicky belt aligner on the exit side.
3. The MG3 top cover looks like the MG1 but the feed tray is different in that is has a built in belt holding pawl and an ammo box holder.
I believe the only thing that can be different are the feed pawls in the top cover. Any one have an MG1 and MG3 cover to compare.
Thanks
