I was just getting ready to ask for help fine tuning the A180 adapters for the M11 and Uzi..... Are you saying I'm wasting my time?
The Mac is close, the Uzi????
You have some cool pics....
Mine didn't take any fine tuning. Rigged it up, gave the bolt a good shot of Rem Oil with Teflon, and let her rip. The fine tuning is in the number of turns you give the drum. The recommended 5 and a half is what works for me. Mine runs much better suppressed than it does unsuppressed though.
