It shouldn’t be too hard, honestly.

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.

Need an SOT FFL (Special Occupational taxpayer) to build it. It’s a machine gun. It would be an interesting challenge to make something similar with an frt. The trigger would somehow need to turn the crank.

Two weeks, and I’ll have the green. Will order then.

Mussy dropped some cad in a matrix chat for a mostly printed uzi. I haven’t examined it closely, but I believe it’s a 22lr.

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

I wonder if silicone sealant, spread flat and cut out, would work for wipes.

I’ve also designed a mac11 recoil reset trigger. I haven’t had a chance to test it yet, but I think it’ll work.

Mine is a drop-in trigger replacement.

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.

Found mine on made-in-china.com shipping and import fees suck, but still less than 100 bones, all in.

So, from my experience with the NaG (I’ve built 3, 2 have exploded)…

Issues with loading/firing/extracting are usually down to the chamber geometry. You need to sand or file a slight cone into the chamber (for extraction) and a “feed ramp” into the top and bottom of the breech end of the chamber (for feeding).

I used rifled barrel liner for all my builds. The scuttlebutt is that a smooth 6mm ID 8mm OD stainless pipe will work better, because it produces less back pressure.

The best way to taper the chamber seems to be chucking the barrel into a drill and wrapping a piece of sand paper over a small rod, held at an angle, while the barrel spins.

I have a video on my odd sea firing the NaG https://odysee.com/@FieldExpedient:6/NaG01:e
