  • Intelligent MOSFET
  • Officially Licensed
  • SSS Gearbox

If you're looking for a weapon which doesn't just look unique you've found it. Built in partnership between ActionSportGames, ICS and HERA ARMS this rifle is an Airsoft gun like no other. Based on the AR15 Mil-spec variant of the HERA ARMS CQR this rifle uses ICS's brand new SSS AEG Gearbox design and is officially licensed and fully trademarked.

The Airsoft replica itself is constructed from a mixture of high quality alloys and polymers, with an Alloy Receiver, Handguard Outer Barrel and Internals, with a Polymer Stock, Magazine, Foregrip and Flip-up Iron Sights. The rifle features a high quality finish, with heavy duty materials leading to a highly detailed and realistic looking rifle. The rifle isn't just a quality build, it also come fully trademarked with all the textual markings and logo shown on the real rifle for higher levels of realism.

Full description


Externally the weapon is based off a mil-spec variant of the AR-15, and then modified by attaching the modified CQR parts. The rifle is a 1:1 replica of its real steel counter part including all the modified which went into upgrading the rifle. The parts were modified for the AEG edition by ICS based on the original CAD design files created by HERA ARMS to make them highly realistic and ensure the scale was the same.

The fixed Hera Arms CQR stock is very unique, with its P90 esque shape, this thumbhole stock is something rarely seen on an M4 and give the rifle a completely new feel and look. The stock is great for use with slings as it features a left and right QD sling loop mount points, as well as two stock sling bars for more traditional sling systems. The stock's length can also be adjusted using stock spacers which allows you to customise the length of the weapon to the perfect required length. To work with an Airsoft AEG the original design has also been modified to accept both batteries and the AEG's motor with no effect on the overall look of the stock.

The Hera Arms CQR grip is something to behold. The grip features a unique shape which offers the user a variety of grip angles to allow for a range of comfortable and stable firing positions. The front of the grip is specially designed to be held with a thumb and finger grip, similar to a P90, which is extremely comfortable hold hold and gives you a strong grip on the weapon. The grip features multiple textured surfaces for extra grip, and is attached to the weapon via the rails 20mm RIS / RAS rail allowing it to be removed and refitted with ease. Another interesting feature is that the grip itself is actually produced by HERA Arms giving it a high quality finish comparable to the real thing.

The handguard is also based off the original designs, and is a replica of CQR rail. The rail is a four point 20mm RIS / RAS rail which allows for 20mm attachments to be fixed to the handguard, the most common on the market, allowing for a wide range of aftermarket parts to be fitted and used. The top rail lines directly up with the top rail of the receiver creating a full length top rail allowing for the attachment of large sights and scopes as well as complicated setups like a holographic and magnifier. The left and right side of the handguard features a QD Sling loop mount point to allow for the easy attachment of slings, and when used with the stock's QD points you can attach a range of two point slings to make the rifle easier to carry.

Special Instructions

ASG Recommends that with the UK M100 Standard  Spring version that you use a maximum of a 7.4v Li-Po battery for the best performance possible.

Please note that this battery will not function using Ni-Mh batteries and requires Li-Po battery. This is due to the low voltage protection built in as part of the SSS MOSFET, please ensure you use 7.4v Li-Po.

The externals of the replica are metal where they would be on the real world gun. This includes things like the outer barrel, handguard, and receiver. If a real world gun has polymer parts then the gun will still be marked as full metal externals, examples of this would be an M4, where the Stock and Pistol grip are always made from Polymer.

Further Information

SSS Self Diagnostic Shooting System

Three Round Burst Mode

The mosfet can be set to fire three round burst instead of full auto for accuracy and to conserve ammo.

Pre-cocking Mode

By default Pre-Cocking is enabled, which pre engages the piston so you can make repeat shots faster.

SSS Self Diagnosis System

Allows you to diagnose problems with the rifle to give you a general idea if the weapon stops firing.

Low Battery Protection

When your battery has insufficient charge the grip will vibrate three times then stop firing.

Switching between Firing Modes

By default the weapon is set to Safe / Semi / Full Auto. To switch to Safe / Semi / Burst please follow the steps below:

  • Set the fire-selector to semi-automatic.
  • Hold the trigger for 10 seconds.

The pistol grip will vibrate once when switching to 3 round burst, or twice when switching back to full-auto

Setting Pre-cocking Mode

By default pre-cocking mode is enabled.

  • Press the trigger once in semi-auto.
  • Switch the fire selector quickly between semi and full auto 3 times in under 5 seconds.
  • The motor will vibrate once the process is completed.

Please note when switching to pre-cocking, or after the piston has been released the system will need to re-detect the piston position. The system may double feed or not fire for the first five shots until the positioning has been memorised.

SSS Self Diagnosis Mode

If the product is operating correctly then you will not need to run a self diagnosis, however this can be helpful for any Airsoft Tech or for personal reference.

The self diagnosis mode checks features such as the battery voltage, the functionality of the trigger system, the fire select, and gear functionality.

Information about the self diagnosis mode can be found in the manual.

SSS System Warnings

  1. Any disassembly or use of non-original parts may result in abnormal product performance. Please ensure you're confident in any modifications you make, or get in touch with our Workshop via our Contact Us Page.
  2. Only use 7.4v or 11.1v Li-Po Battery in this replica, any other battery may trigger the low-voltage protection system and cause the rifle not to fire.
  3. When the battery power is too low the pistol grip will vibrate three times to notify you that the battery requires changing.
  4. When the battery power is too low the system will switch to safe mode to prevent damage to the battery. The pistol grip will vibrate once when the trigger is pulled as a warning.
  5. If the system detects a problem with the gearbox during use the gun will be switched to safe mode to prevent damage to the weapon. The pistol grip will vibrate once when the trigger is pulled as a warning.
  6. Please note that the self-diagnosis function is only for reference, and may not directly reflect the cause of the problem. If you are unsure what is causing the problem please ensure you get in touch with our Workshop via our Contact Us Page.
  7. The system will return to its default settings once the battery is removed. Pre-cocking will be re-enabled and the gun will switch back to Safe / Semi / Full Auto.
  8. If you enable pre-cocking mode without the magazine installed the weapon will not fire a round on the first shot. This is so the system can re-learn the positions of the piston.
  9. Please note that whilst in pre-cocking mode if the hop-up is set to be full off BBs will be free to roll down the barrel. Please ensure that a small amount of hop is always applied.
  10. If you release the spring either via removing the battery, or activating the decocking mechanism via the mock bolt release, the system will need to re-detect the piston positions, meaning the weapon may not fire a round, or double feed for the first few shots.
  11. To maintain functionality of the weapon and to protect the weapon do not remove the fuse.
