 British Sten Mk2 Parts Kit, with Barrel, Tube, Good Trunnion, Mag, 9mm — WWII Icon

This is a parts kit for the Sten Mk2, the British submachine gun built for cheap, fast wartime production during WWII. It’s listed with a barrel, receiver tube, a trunnion noted as good condition, and one magazine. Here’s the detail to confirm first: “good trunnion” is a condition claim, not a universal standard. So ask directly what that means for this specific kit before you buy.

Why the Sten matters historically

Britain designed the Sten specifically to be cheap and fast to manufacture. You could produce roughly 15 Sten guns for the cost of one standard rifle. It used 9mm Parabellum, the same ammunition as many German pistols and machine pistols at the time, which made it practical to issue to regular forces, resistance fighters, and partisan units across the war. That production history is part of why Sten kits remain popular with collectors today.

Material, size, and weight

Steel stampings make up most of the Sten Mk2’s construction. That’s exactly how Britain kept production fast and cheap during the war. A standard Mk2 ran about 30 inches overall, with a barrel length around 7.75 inches and an unloaded weight close to 7 pounds, though these numbers varied slightly between wartime manufacturers. Exact weight, barrel length, and trunnion condition on this specific kit: verify, since original WWII production runs differ lot to lot, and “good trunnion” needs its own confirmation beyond the listing description.

Trunnion condition drives most of the value here

The British Sten MK2 parts kit w/BARREL, tube, good trunnion,mag,9mm WWII icon is the part that locks the barrel to the receiver tube and takes the brunt of firing stress. A worn or damaged trunnion is one of the most common issues with surplus Sten kits. So if this listing specifically calls out a “good trunnion,” ask for close-up photos or a direct condition description before you commit, since that single part affects both safety and resale value more than almost anything else in the kit.

 Fitment British Sten MK2 parts kit w/BARREL, tube, good trunnion,mag,9mm WWII icon

This British Sten MK2 parts kit w/BARREL, tube, good trunnion,mag,9mm WWII iconis built for the Sten Mk2 pattern specifically. It is not interchangeable with Sten Mk3 or Mk5 parts without modification, since those variants changed receiver construction and stock design. The Mk3 welded the receiver and barrel shroud together as one unit, while the Mk5 added a wood stock and foregrip not found on the Mk2. So mixing parts between these variants isn’t a simple swap.

The mix-up we see most: buyers assume any Sten parts kit works with any Sten build. It doesn’t. Confirm your receiver tube and trunnion are both genuinely Mk2 pattern before combining this kit with other parts. If you already own a Sten receiver tube, verify its markings match Mk2 spec specifically, since Mk2 and Mk3 tubes aren’t interchangeable without rework.

Because this kit includes a receiver tube from a submachine gun platform, how it ships into the UK and EU depends entirely on that receiver’s legal classification. Through eurogunandpartshub.com, a properly deactivated receiver meeting your country’s standard may ship as a non-firearm item. Anything that doesn’t meet local deactivation requirements needs to move through a licensed dealer and registered transfer channel instead.

We recommend confirming the receiver’s exact deactivation standard with us directly before ordering. Also check with your own firearms authority about whether that standard is recognized where you live. Historic military parts kits sometimes face import rules that differ from standard accessory parts, so this is worth a direct conversation before you commit.

What buyers usually ask first

Demand unconfirmed for this specific kit in the European market. The Sten holds genuine historical interest across the UK and Europe, given its deep WWII and Commonwealth military history, but we don’t have sales figures for this exact configuration here.

A few questions come up consistently before people buy a kit like this. First, is the included magazine original wartime production, or a later reproduction? That’s worth confirming directly, since original magazines often carry separate collector value. Second, does “good trunnion” mean fully functional, or just free of obvious damage? Ask for specifics rather than assuming either way. Third, can this kit be built into a functioning firearm? That depends entirely on your country’s laws around historic submachine gun receivers, so verify with your local authority before assuming anything.
