Well, it's been a loooooong time but I finall managed to finish the MAC 10.
Scope rail is 3d printed. Silencer is a heavily modified from the one that comes with the airsoft. There are a lot of inaccuracies if you start to nit-pick. Spacer between silencer and MAC should be thicker, scope position and rail are not 100% and a bunch of other small things. Normally, these things might drive me nuts but since this is a 'found parts' build and I didn't want to work on it forever I figured it's 'close enough' because overall it looks the part. If there was an all-metal MAC 10 available I might've kept going but there is, as far as I have found, only this plastic one on the market- the others are MAC 11s.
A couple months ago, I also finally found a good stock of copper and brass bar, so maybe I'll get back to the eagle bracelet soon as well. We'll see!
"Finished" my MAC 10 recently too. I've still to source some proper Leupold mount base and rings [which is why my scope has blue tape on it, so it doesn't get scratched up from it current, temporary rings]
