Mossberg M590 Chainsaw Spring Shotgun with 500 BBs (Short – Clear – Cybergun – RT270741)
This Cybergun set is a short, clear-bodied spring airsoft shotgun styled on the Mossberg 590 Chainsaw, supplied with 500 BBs, reference RT270741. Cybergun is known for officially licensed replicas, and this shotgun carries the Mossberg name, recreating one of Mossberg’s most unusual modern pump-action designs in an affordable, easy-to-use form.
The clear body lets you see the spring mechanism working inside, which newcomers find fascinating and which makes the shotgun instantly identifiable as a replica. With BBs included in the box, it is ready for target shooting as soon as you get it home.
How it works
A spring shotgun needs no gas or battery. Work the pump fully back and forward to compress the spring and chamber a BB, then pull the trigger to fire. Every shot is cocked by hand, so it is reliable, cheap to run and works in any weather.
Pump-action shooting is great fun and builds good habits: a full, firm stroke every time gives the most consistent shots, and the rhythm of pump and fire soon becomes second nature.
The Chainsaw styling
The real Mossberg 590 Chainsaw is a short, compact shotgun built for close-range work, and its unusual look has made it popular with fans of films and games. This Cybergun replica follows that compact, short-barrelled styling; see the product photos for the details of the grip and furniture.
The short length makes it easy to handle indoors and in tight spaces, and a light spring replica like this is easy for younger and newer shooters to manage.
Getting started
Read the manual so you know where the safety is and how the magazine loads. Fill the magazine with some of the supplied BBs, fit it, work the pump with a full stroke and fire a few shots at a safe backstop. If the shotgun has an adjustable hop-up, set it a little at a time until the BBs fly level.
A garden or indoor range with a proper BB trap is a good place to practise. Always wear eye protection, even when target shooting.
Choosing BBs
The supplied BBs get you started. When you buy more, choose good-quality, seamless 6mm BBs; for a light spring shotgun, 0.12g or 0.20g BBs are a sensible choice. Cheap, misshapen BBs are the most common cause of jams in spring replicas.

Care and maintenance
Spring replicas need very little maintenance. Keep the magazine and loading area free of grit, and put a tiny drop of silicone oil on the moving parts of the pump now and then. Do not leave the shotgun cocked when stored.
Clean the barrel with a rod and dry patch if accuracy falls off, use clean BBs, and store the shotgun in a dry place out of direct sunlight, which can discolour clear plastic over time.
