 What can be done with a sten?

I noticed in another post somebody brought up that a .45 acp sten would be interesting, Has anybody tried that conversion?

I've seen 7.62 and 9mm largo conversions and even seen a .22 lr conversion discussed once on another forum, The .22lr conversion sounded like it used 9mm chamber inserts that had to be reloaded manually with a cleaning rod, I assume it had a lighter spring and bolt also. It was not the owner of the sten so I could not ask any questions, just somebody that shot it at a shoot.

I know a sten is not a AR, or a MAC but is there anything different that can be done with them?

Suppress it.

Heard there was someone working on a .22 kit but idk if it went past the drawing board

I'm not sure how a .45 conversion would work. The magazine well is much too small for either Thompson or Grease Gun magazines. Perhaps you could use the old .45 Uzi 16rd mags. But at about $100 each, that gets expensive very quickly. And changing a magazine housing is not all that simple.

The best STEn conversion is to a Sterling. I like the STEn a lot. But the Sterling is a much superior weapon in every regard.

I think most guys who want to modify and gunsmith FA guns just get a MAC of one kind or another, since it has an easily detachable lower, similar to the way the whole M16 lower pops right off.

They're easy to work on and upgrade, they're inexpensive and they have pretty much no collector value.

And there is a zillion of them in the registry.

A lot can be done to a Sten IF you're willing to make changes to the front site so that it's easily removed/installled AND the mag well is not serialized. Being able to replace the mag well opens up lots of other possibilities.

I'm playing with two ideas.

1. Top folding stock.
2. Glock mag conversion.

I am very good with metal work so I am going to give the stock a shot first. I just ordered a KP44 parts kit. I am going to weld the rear trunion to a sten pistol grip. For dissasembly I will mill a chanel and place a spring loaded rod and a button on the back for dissasembly of the sten. Depending on the position of the charging handle I MAY have to make it a under folder. My transferable sten is still months off so I will have to use a catco for the time being for fitting.

If it works GREAT, if not, trade bait.



For the glock mag conversion, It's going to take a bit more but I have plenty of tubing at work and I should be able to make a mag well and release that will work with glock mags. It will have to be angled at a slant but I would love to be able to use my glock mags in my sten.

i have a buddy working on a .22 conversion kit, and a .45 conversion kit, for the MKII sten right now. plan is to have them both up-and-running prior to our mid-spring hometown shoot.

the .22 conversion is pretty close already. i'll try to post vids when it's going.

he already runs several small businesses and a machine shop, so he is tooling up with the idea of producing to sell (he is getting his website up at the moment as well). i don't really want to post much more about the kits, lest this be construed as a "for sale" post.

like i said, when they are running, i'll post vids.

The Achiles Heel of the Sten is the magazines. Umpteen contractors, poor fit, single-feed, absolute bitch to load. I think whoever could make an adapter for UZI mags with a modified double-feed bolt would be in business. Obviously a .22 conversion is a great idea for any SMG, still waiting for one for the MP5!!!!!!

I have never had issues with Sten mags unless they were physically damaged or filled with crud inside. The ONLY way to load them is using a mag loader and the Uplula loader is the only way to fly. A simple mod allows it to be used on Sten & grease gun mags as well.
Sten mags use to be dirt cheap and extra mags that work is a must have for any SMG. I had more problems by far with Uzi mags when I had a select fire Uzi.

9mm Sten mags on my Stemple 9mm conversion. These were made the same size as the grease gun mags since the SMG was in .45 before.

So the Uplula works on Sten mags! My fingers hurt for days after loading a couple the old fashioned way. And my Sten modified M11/9 can rip though it a hell of a lot faster than I can wince through loading them. I was eyeing an Uplula but didn't know if it'd fit. Did you have to modify yours? A quick Google search turned up some dremel and file work. Is this what you did?


PS. What width should the feedlips on a properly spaced Sten mag be?

You are not alone my friend. I have a couple of the original WW2 mag loaders, they make it a bit easier to load but more time-consuming. The only way to justify the effort is by using otherwise 'dead' non-range time, loading while shooting is next to impossible. Compare that with Sterling mags that a child can load quickly to full capacity by simply pressing down or UZI/Colt mags that need a little bump for the last ten rounds of pressing down. Grease Gun and Thompson .45 mags are easier than the Colt/UZI.

I'm not drinking the STEn mag coolaid, I fakkin' hate the things. If I had a non-historic STEn 'tube' gun I'd have it rebuilt as a Sterling without thinking twice.

A good vid on the Uplula mag loader mod. A hand file and / or a dremel too is your friend.

As to the feed angle your target is around 8 or 9 degrees If you have several mags number them and test fire ALL of them. If you have problems you can then address the issues. I have found the biggest stoppage problems being dirty mag bodies , springs and the transition area where the double column of rounds transition into single feed. Once cleaned and lightly lubed then look at the feed angle of your mags. I would take ANY steel Sten mag over the Zytel plastic POS mags floating around. My friends have full auto Stens and its a simple, reliable and decent firearm IF set up correctly. I think there was over 14 million Sten mags made so I am sure a few bad ones are floating around.

Double feed mags are super easy to load by hand and are by far more popular. I could have used Suomi mags for my 9mm conversion which is an excellent mag BTW but I am building a drum mag in 9mm also which single feed was simpler for me to build on.
