Professor Parabellum

I heard that there are mistakes in these books, like bolt weight in the mac 10 book, is that true?

bolt weight is honestly not super important, most blowback bolts' weight is way over the safe treshold and usually to make the fire rate somewhat controllable.

Is this the David Gingery of firearms?

I've made a couple of his designs. The STEN gun was a hoot to shoot.

Thanks dude

About 12 hours of work I total, but I fucked up and had to restart a few times.

what tools did you all need?

Angle grinder, wire welder, pneumatic/electric cutoff tool, a drill press and an XY table for my drill press.

I found one on making a Borz SMS

The first Mac 10 guide is horribly unsafe. Rumor has it the later revisions won't kill you, but I wouldn't know. In other words, weigh your shit.

May the MurderCube bless you for your kindness.

Legit. I might actually try and build this. Many thanks anon.
