If you love a piece of history, you'll love the AGM STEN MK II AEG SMG! This full metal STEN gun replica is based on the real steel STEN MK II, the most commonly produced variant of this legendary British SMG. Constructed almost entirely from steel with all the details a true STEN fan would expect, the AGM STEN is internally equipped with a version 7 gearbox and fixed HOP-up optimised for 0.25g BBs, giving you a simple and reliable platform, just like the real deal.

Whether you're looking for a base gun for a post-apocalypse build or a STEN for your WW2 OSS, French Resistance or British Army loadout, the AGM STEN MK II is a fantastic choice for a superb price!

Full description

Description

Used extensively byBritish and Commonwealth forces throughout World War II, The STEN MK.II is the most common variant of the STEN Gun family, with roughly two million produced throughout the conflict.

STEN guns were of simple design, quick to produce with extremely low production cost. This makes them effective in the hands of shooters of any skill or training level, ideal for insurgency and resistance groups such as OSS and the French resistance.

This 6mm Airsoft replica lets you relive a part of history, should you be re-enacting or participating in World War II-themed skirmishes, with the AGM you can really look the part as the replica is realistic thanks to its alloy construction and 1:1 scale to its real-world counterpart.

The steel externals give this replica a realistic look, weight and feel, mimicking real STEN perfectly. STENs were rapidly built in factories and even bicycle repair shops, often cobbled together from whatever parts were available at the time, this Airsoft Gun replicates this haphazard manner of assembly perfectly without being rough around the edges.

The open bolt design replicates the original with a fixed firing pin on the front of the bolt. The main difference between the AGM replica and its real-world counterpart is that the magazine is constructed from high-density polymer, however, it retains its low-capacity design with 50rnd capacity. If you want more capacity, check out the 120rnd Mid-cap for the STEN.

Featuring a simplified barrel sleeve, protruding barrel and magazine guard assemblies of the MK II STEN with the simplified Fixed Tubular T Stock of the MK.1* STEN, this STEN replica is flawlessly authentic. Just like the real MK II, you can rotate the magazine well into the vertical position for storage by pulling the retaining catch on the front of the magazine well. The STEN is packaged in this configuration in the box, and to get going you'll need to pull the catch and rotate the magwell over to the left side before inserting your magazine.

The Stock is fixed in place during use; however it can be removed to access the internal battery compartment, we recommend a 7.4V 1300mAh 25C LiPo Stick Battery as it will fit nicely on the rear of the gun. The controls of the STEN are simple; there is no Fire Selector or Safety setting, and the no-frills Iron Sights are fixed in place.

Forget all your modern tactical railed kit and other contemporary nonsense! It's time to get back to basics. The STEN MK II AEG is the perfect platform of choice for the history-loving Airsofter. With both realistic construction and functionality on the field, the AGM STEN MK II is ideal for re-enactments and historical skirmishes alike!

Special Instructions

Please note that this Airsoft Gun does not feature a Safety or a Semi-Automatic function. Just like the real thing, once loaded the AGM STEN RIFLE MK II is ready to shoot and will only fire on Fully Automatic when the trigger is pulled.  While some may commend this as an impressive replication of an authentic design feature, it does create something of a safety concern. We strongly recommend not connecting the Battery or inserting a Magazine until absolutely necessary.

Special Instructions

These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.

FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.

Tap the tabs below to open the relevant chart for your replica.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.

Bought alongside an MG42, they share mags too.
Fir a moderate cost replica it's well made, looks the part and even has the turning mag insert that acts as a cover for the magwell when not in use.
The charging handle does move, but is just for the image, it does nothing, nor is it spring loaded. Just put it where you want and tighten the knob to keep it there.

Seems to fire ok, looks good with a repro sling, perfect for game play.

As with most patrolbase bits I've bought, it arrived pretty quickly too.
