There’s nothing about heat treatment in the current documentation. Just drilling and ecm the rifling/chamber.

It should. Brownells 22 liners are about 8mm OD. That said, there’s a beta over at BLC that uses a drilled bolt for a barrel.

If I were turning it myself, I’d leave a little more wiggle room. 1mm wall thickness feels a little sketchy to me.

I’ll get to it eventually. I took the last month off from 2a builds. I gotta get back in the groove.

I got a plastic toy version from aliexpress… I think it would be pretty simple to make it shoot 22lr.

Honestly, I’d aim for making one of the larger “cell phone” guns.

The problems with the life card are numerous, but mostly, it’s too small, too slow to open and aim, and nearly impossible to aim.
