NotaGuntuber on the sea has a video of him making a bronze one. He involved some CNC work, but it can be done by hand. The tricky part with the bronze is getting it bored out to .75" as the tubing comes smaller. Patience and lots of stepping up of bit sizes followed by a .75" reamer will get you there.

I’ve been wanting a Ruger MK for a while. Plan on building as many as I can. 😁

I have one in the plans for the future along with a bronze body, but both I’ll probably be doing those as a MKIV once I convert the jigs (assuming its feasible). Those are plans for after I finish my MKR(evival).

They used the Hitchhiker retractable stock.

16" from breech to muzzle.

Had to switch gears from my MK project and print this!

Sweet! I’ve switched to a .6 a while back and need to just adjust my width now. Everything else was using your settings. I was using .62 width.

Music wire. Precision Brand. 0.051"

Changeable grips would be nice.

Finally together and functional tests succeed. Now to get some ammo.

I believe the safety was removed for more strength. I’d have to compare the boomer with standard frame to see where that strength is though.

Let the building commence!

I have 2 BCA uppers on printed lowers. They work fine. They are heavy. LRBHO (last round bolt hold open) needs a special 22lr replacement if you use a standard AR lower design. deAR22, HD22, EZ22 lowers should all work if memory serves me.

Waiting for my Colt Mustang II from EGP. Magazine arrived today.
