My 300 blackout trimming station

[TommyGun]

I built a 300 blackout ar and needed to trim 556 cases down. So I designed a tab box to mount a cheep harbor freight mini chop saw on. Have a look.

Looks like it works pretty good. I didn't realize that is where the 300 blackout case came from. Learn something every day.
