Well I screwed up and need help

Get some Kroil and soak it for a couple days.

If it is an SS mite you can soak it in a 50/50 mixture of vinegar/hydrogen peroxide. Be careful with the fumes from this and disposal of this. Do some research on the mix before hand. You are creating lead acetate when it dissolves the lead.

 

I have luck using Strike Hold to unstick the tough stuff. It is a true penetrating oil and uses capillary action to get into those tight spots. good luck

 

Welcome to Mite ownership! I run a stainless Mite and know exactly what you're dealing with. Once you have it apart I highly recommend slathering (and I mean getting after it) the threads and baffle stack in anti-seize, as that should make disassembly a non-issue moving forward.

Aside from soaking the can or freezing it, the best way I have found to break it loose is to heat the can up simply by using it, and then threading the baffle stack out while it is still hot using the disassembly tool. You'll want a heavy pair of leather gloves or similar to handle it. It's not a bad idea to make sure that the stack will unthread after each use at the range either.
