Tested the DI 30 Uzi and I can get it to open the bolt, but that was it. I had a light buffer with std spring set up. I didn't have a top load in it but it was close. When I get back to the shop we will play with the load and set up a bit plus might try some Autocomp powder. That stuff is funny to work with, but it does generate some gas. Got some nose up jams running out of a Tok mag set up, so this is a spare time project.

I have gone so far as to take all the weights out of a buffer to get light loads to work. Both in a 300 Blackout subsonic and in a light load only 7" .223 pistol. The light load .223 with a can is real low noise. That load is 2400 I think.
