Description

This Airsoft Submachine Gun is based on the Model 11 Platform, and is an incredibly fast firing SMG with a realistic Gas Blowback Action that provides a kick in the shoulder. Because your face is so close to the action when you're firing, it is a very immersive shooting experience that is almost frightening when you pull the trigger.

The Gun is mainly constructed from Polymer to keep it as lightweight as possible, enhancing its' viability as a secondary or backup. This also means that it works better; as we know that a cold Gas Gun does not work as well as a warm one, and the Polymer helps it return to ambient temperature much quicker. It comes included with a Polymer Suppressor that is easily threaded onto the Outer Barrel, and really completes the look of the Gun. The back of the Replica has the typical Folding/Sliding Stock that can be left closed, or fully extended to brace the Gun against your shoulder. The Magazine holds a total of 42rnds, and is filled from the top using a Speedloader like any Pistol Gas Magazine. The Magazine release is located on the rear of the Pistol Grip and can be accessed from either side of the Gun, meaning this replica is viable for Left Handed users as well. The Fire Selector is not ambidextrous, but is easily accessible and offers both Semi and Full Auto fire modes. A set of integrated Ironsights on the top will help you aim your shots, but let us be realistic, this thing is designed for full-auto hip fire. An Ambidextrous Safety can be found inside the Trigger Guard, and will lock the Trigger to prevent the Gun from firing.

The important thing to note with this SMG (and any other M11 / Uzi replica) is that it is an OPEN BOLT DESIGN . An Open Bolt Gun has the bolt locked to the rear, and then slams forward to fire the Gun, the exact opposite of an AR Platform rifle, for example. Please always lock the Bolt to the rear before inserting/removing a Magazine, as slapping a Magazine into the bottom of the Bolt (when it is closed) will not be healthy for the replica. This is also great practice for those who plan to transition to proper Firearms later in life, as this muscle memory can save you from a potentially embarrassing mistake on the range.

Special Instructions

Please do not insert or remove a Magazine into the replica without the Bolt being locked to the back, as it is designed to be operated this way to match the real world firearm.

The magazine provided with some of our HG-203 GBBs has a warning sticker on the outside which references CO2 cartridges. This can be ignored and was applied by mistake at the factory. This magazine is a Green Gas magazine and does not accept CO2.

As with any Gas Blowback Gun, the use of Silicone Lubricant is absolutely paramount to its' long term performance. Please ensure you are regularly lubricating the moving parts on your Gas Replica, otherwise it could develop faults.

Joule Charts

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.

This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.

In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.

Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.

Rated 5 out of 5 Anonymous Written on 12/07/2025 fantastic little toy for the price, a lot of fun to spray. The magazine is phenominal; try to empty a normal GBB pistol and the you'll usually lose pressure by the last shot, this thing holds enough gas for at least 2 full loads of BBS, i suspect it will never fail to dump the whole mag without losing power or freezing up. you want more mags though, they do not last long.
