2018 Frankengun Challenge

By The Small Arms Review Editorial Staff

What is a “Frankengun”?

A “Frankengun” is just what it sounds like—a cross between Frankenstein’s Monster and a gun, in this case a machine gun. The phrase goes back to the early Internet days when legal machine gun owners would cross-pollinate weapon designs using parts, and sometimes movie voodoo type add-ons, to create something that fit their idea of a fun gun. Frankengun contests are held occasionally, and we at Small Arms Review like to encourage our readers to participate, making sure it’s legal as they do so. Much like our fabled “MacWaffle” contest (Small Arms Review Vol. 2, No. 4), where readers had to make a working waffle iron out of MAC flats, this is about having some fun.

We received several entries but chose the top 2 presented here. The winner of the Frankengun Challenge will be judged by the readers and receive a 3-year subscription to both Small Arms Review and Small Arms Defense Journal. An RKI Certificate will be provided for those who put in an entry, which will be suitable for framing.

The S&W76/MK760
Magazine Problems Forced Owner to Do Some Surgery

This project started when one of my friends purchased an MK760 that was jamming. The gun would run just fine if you held the magazine forward and did not let it move when you shot it. The magazine well on his MK760 was too large and would let the magazine flop all over the place. The rounds would never be presented the same way causing feed jams. Looking at it and the history of the Smith & Wesson 76 / MK760, it should have always been designed like the Swedish “K” and been able to accept Suomi sticks, drums and coffin magazines. So I went to work.

Not knowing beyond a shadow of a doubt that I could get the drum magazines to work without having to cut too much out of the receiver and weakening it, I decided the best course of action would be to make a post sample 760 receiver to convert and work out...
