subgun24 Posted June 17 Report Share Posted June 17 I designed a 22LR conversion kit for the Smith & Wesson 76 / MK760 submachine gun. Let me know what you think and if it's something you would be interested in.

KickStand Posted June 18 Report Share Posted June 18 I really hope to get one of these. You need an adapter for the lightnin grip loader. It’s a game changer. Quote Link to comment Share on other sites More sharing options...
subgun24 Posted June 18 Author Report Share Posted June 18 Good suggestion. I will design the lighting adapter and test that out. 1 Quote Link to comment Share on other sites More sharing options...
Got Uzi Posted June 18 Report Share Posted June 18 Very nice indeed. I’m working on the drawings to do one for a Swedish K. I’d be interested in how you did your magazines as they are very similar. Quote Link to comment Share on other sites More sharing options...
subgun24 Posted June 18 Author Report Share Posted June 18 My magazine would probably just take a little tweaking for the Swed K. You welcome to use my mags for your kit. They are made of seven 3D printed parts, a spring and metal feed lips. Quote Link to comment Share on other sites More sharing options...
rcortland Posted June 18 Report Share Posted June 18 I see you've also got a placeholder item on your website for a Sterling Mk4 .22 kit. I will be following both that and the S&W 76 kit with great interest! Quote Link to comment Share on other sites More sharing options...

eMGunslinger Posted June 25 Report Share Posted June 25 Any MG that has a 22 kit is always a win, nice work the feeding and ejection looks really nice. Quote Link to comment Share on other sites More sharing options...
MPFiveO Posted June 25 Report Share Posted June 25 (edited) So, some follow up questions. Who made the test gun? What ammo are you running? *I looked more closely and could see the MKA on the magazine well. Is this a Fruithurst, AL gun or California gun?

subgun24 Posted June 25 Author Report Share Posted June 25 This particular gun is an Irvine MK760. I have two MK760s and a SW76 as well. Initial design was designed around the MK760. Then, when I tested it in SW76 it needed some minor design changes. After I got it to work in the SW76, the MK760s still ran as well. The only differences I had between the two Mk760s was that the mag well had some dimensional differences. But as long as the mag fit the smaller dimension, all was good in all three guns. The ammo I use is Aguila 40 grain High Velocity. It is the cheapest ammo and I find that it works great. 1 Quote Link to comment Share on other sites More sharing options...
MPFiveO Posted June 26 Report Share Posted June 26 You zeroed in on exactly what my concern was. I have a Fruithurst MK760 and a Panama City 76A1. They are the same gun but different dimensions. I'd be happy to test the kit in my guns if you want some feedback. I'm retired with all the range time in the world. I also have piles of .22 ammo including the stinky primer Aguila.

john Posted 21 hours ago Report Share Posted 21 hours ago I like the project too and would be interested in a kit and some mags too. I have a SW76 that runs great, has a lotta rounds through it. Have two '28 Thompsons with .22 just and they are a blast to play with! So, I would love to be able to run .22 through that 76. Also love to find a .22 kit for my Sten Mk III if anyone is considering that platform. Question.....how do you get the steel lips in a 3D printed mag? Are they sturdy enough to last awhile?

subgun24 Posted 17 hours ago Author Report Share Posted 17 hours ago The magazine design is one of the strength of the kit. The steel feed lips will essentially last forever. It is 1mm thick chromoly steel. Question for you, what color magazine would you prefer? I am thinking a light grey or dark gray although I do like the blue a lot. I am making a similar kit for the Sterling. It's possible that I would be able to adapt it to work with a Sten. Quote Link to comment Share on other sites More sharing options...

Blue! is cool BUT I am LAZY I want EXTRAs, even if i an NOT shooting a machine gun at the range i take 1 so if some kids show up I let them shoot one. and 1 magazine just doesn't work, no matter what caliber the gun is in.
