H&K MP5A4 RIS Full Metal AEG Standard (Umarex/Cyma, Black, CM041B)
This is the H&K MP5A4 RIS, a licensed electric airsoft SMG from Umarex and Cyma in Cyma’s Standard range, listed as full metal and finished in black. The A4 is the classic fixed-stock MP5, and this version adds a railed handguard, so you get the traditional profile with room for modern accessories.
Few submachine guns are as recognisable as the Heckler & Koch MP5. Since the 1960s it has served with police and special forces around the world in a whole family of variants, and that variety carries over into airsoft, where there is an MP5 to suit almost every playing style.
The fixed stock gives a solid, consistent cheek weld, which helps with steady, accurate shooting, and many players find it the most comfortable MP5 to use. It suits CQB, woodland and milsim players who want a dependable, classic SMG.
The A4 RIS design
A retailer listing for the Cyma CM041B describes a fixed stock, a metal RIS handguard, a 229mm inner barrel and an overall length of approximately 710mm. Please check the product images for the exact sights and rail layout of this version.
The railed handguard gives you space for a torch, laser and grip, while the fixed stock keeps the classic MP5 look and feel.
Handling
With its fixed stock the A4 shoulders the same way every time, which helps you find your sights quickly. Practise smooth movement and fast reloads, and keep accessories light so the SMG keeps its quick handling.
How it works
An AEG (airsoft electric gun) uses a rechargeable battery to power a motor, which turns a set of gears inside the gearbox. The gears draw back a piston against a spring and then release it, and the rush of air pushes the BB through the hop-up and down the inner barrel. AEGs are the most popular type of replica because they are consistent in all weathers and cheap to run, with no gas to buy.
Getting started
Before your first game, charge a suitable battery fully, fit it as the manual describes and connect it carefully. Load a magazine and start with the hop-up turned off, then fire a few shots at a safe backstop and add hop a little at a time until the BBs fly flat without rising at the end of their flight.

Compatibility
MP5-pattern AEG magazines fit this replica; Cyma MP5 magazines are the safest choice, and most mainstream MP5 AEG magazines work, though it is worth trying a new magazine before relying on it in a game. We also stock Cyma MP5 mid-cap magazines and MP5 speedloader adaptors.
The battery’s size, type and connector are not given in our listing, and MP5 variants differ in where the battery fits, so please check the manual or contact us before buying a battery. Use good quality seamless 6mm BBs.
Care and maintenance
Take the battery out after every game and store it away from the replica, and charge LiPo batteries only on a proper balance charger that you are supervising. Clean the inner barrel with a cleaning rod and a dry patch every few games, as dirt and broken BB fragments are the main causes of flyers.
Use good quality seamless BBs of a consistent weight, check external screws and accessories before each game day, and store the replica somewhere dry. Leave internal gearbox and electronics work to someone experienced with AEGs.
Who is it for?
The MP5A4 RIS is for players who want the classic fixed-stock MP5 with the flexibility of a railed handguard, as a dependable SMG for CQB, woodland or milsim.
Please note: The listing does not say whether a battery, charger or spare magazines are included, so please ask if you need them. Always wear suitable eye protection when using any airsoft replica, and have it chronographed at your site before play.
