Anyone got a deactivated MKII STEN ?

Recommended Posts

I'm fabricating a non functional replica STEN mkII and need just need to know what the thickness of the butt plate and grip piece steel sheet is ?

And the spacing and diameter of the holes in the barrel sleeve. 

Thanks.

Thanks that's perfect, can you tell me the thickness of the sheet steel used on the grip plate ?

 

Are there 3 sets of 3 holes equally spaced around the tube ?

Yes, those plans aren’t accurate, there’s some dimensions that if you follow, they won’t fit. Also, they are different to the original so aren’t interchangeable.

The whole front barrel trunnion is different, you can’t even compare dimensions as they are so different. The  face of the trunnion should nearly in line with the magazine opening, the one  in the plans is something like 4mm out. Also the ejection port is almost parallel with the mag opening, a real STENs ejection port is something like 20mm further back.

The original sizes will be in inches imperial so what looks 6mm or near would most probably be 1/4 inch 6.35mm etc etc

yes they are. The thickness on the grip plate should be the same.

The threads are out to, the TMH cover is held with 2 x 2BA round head screws the same as the mag release catch retainer screw. The barrel nut, if I remember correctly is 22TPI UNS.

I'm only really interested in the external dimensions as my replica will have the barrel and barrel sleeve fixed in place, no trigger mechanism, and no way to feed cartridges from the magazine.

The lockdown has put me back on this project, I've got some measurements off a mk5 but I'm still looking for Mk II stock dimensions. 

And a cheap magazine.

Sten mags at the big shows were £3 a pop not that long ago brand new in grease. Cant get them cheaper than that. which stock do you want as there are two types, T stock or the  gun shape open frame job. You can buy them on ebay as i have seen these up for grabs on there from time to time.

Also in these Plans. The barrel Latch, or in Reality. The Mag Housing Positioning Plunger. Is nothing like an original.....

& missing the barrel nut retainer plate. Which would prevent the barrel nut from unscrewing when being fired on a Live fire Sten.

You would have to add the entrance fee to the show and travel costs. 

I don't want to buy any parts except a mag , mainspring and its end cap which are not practical or economical to fabricate.

Those plans are certainly different to what I'm finding by measuring STENS. The rumour is that they are from a metric Israeli STEN copy.

It’s not an Israeli copy, those are near identical to the Standard STEN to the point it’s hard to differentiate at times. I think the plans are just easy DIY plans removing some of the more difficult engineering aspects.

OK, I'm finding 2 mm or more difference in some parts like the main tube end bushing, and the barrel sleeve is 60 mm longer than a MK II. I don't trust those plans at all.

No I wouldn’t, it would be easy to custom fit everything but it could end up looking nothing like a correct mk2

Have you seen this chap on Gun-star? He’s well known and legit.

Perhaps you could buy some of the harder parts to make? He sells a kit or individual parts so can be your choice. I’ve bought a spring kit and a few other bits from him and he’s very quick to respond to messages.

I will see how it turns out first before I buy any parts, the magazine, the main spring and its cup are the only parts worth buying for me personally as I worked in metal work, welding and fabrication . ( now retired )
