Description
Cyma CM028B AK RIS Sports Line (Full Stock, Metal Gearbox, CYMA-CM028A)
The Cyma CM028B AK RIS from Cyma’s Sports Line is an affordable AK-pattern AEG that combines the classic AK silhouette with a railed (RIS) handguard for mounting modern accessories. This listing is described with a full stock and a metal gearbox, giving you the dependable, no-nonsense AK feel that has made Cyma’s AKs so popular with newer players and budget-conscious skirmishers.
Cyma is one of the best-known manufacturers of entry-level and mid-range AEGs, and its AK designs have a long track record for reliability. The Sports Line keeps costs down by using a polymer body with metal parts where they count, while the metal gearbox gives a solid base for later upgrades. It suits first-time buyers, players who want an AK without a big outlay, and anyone looking for a robust rental-style rifle.
Build and furniture
The body is polymer, keeping weight and cost down, while key external parts are metal. The RIS handguard gives rails around the front of the rifle for a torch, laser, vertical grip or other accessories, so the classic AK can be brought up to date to suit your loadout.
AK replicas are known for their simple, robust controls: the large selector lever on the right-hand side and the paddle-style magazine release are easy to use with gloves and quick to learn.
Internals and performance
Inside is a metal gearbox, which for Cyma AKs is a Version 3 design. Version 3 is a widely used gearbox type, so replacement and upgrade parts are easy to find. The hop-up is adjustable, letting you tune the rifle for the BB weight you use, and fire modes are safe, semi and full auto.
Cyma AKs normally use a high-capacity, wind-up magazine; a hi-cap magazine holds a large number of BBs and is wound with a wheel on the base to feed them. If you prefer a quieter, more realistic magazine, mid-capacity AK AEG magazines are a popular alternative.
Getting started
Charge a suitable battery fully before first use, fit it as described in the manual and start with the hop-up turned off. Fire a few shots at a safe backstop and add hop gradually until the BBs fly flat. Have the rifle chronographed at your site before your first game.

Accepts AK-pattern AEG magazines; most standard AK AEG magazines will fit, though very tight or loose fits can occur between brands, so try a magazine before relying on it at a game. The RIS rails accept standard 20mm accessories. Check the battery space in your rifle before buying a battery, as AK stocks and handguards vary in size.
Care and maintenance
Remove the battery after each game, store LiPo packs safely and charge them only on a suitable charger under supervision. Clean the inner barrel regularly with a cleaning rod and dry patch, and use good-quality seamless BBs. Wipe the rifle down after wet or muddy games, check that screws and rails are tight, and store it somewhere dry.
Who is it for?
A good choice for newer players and anyone wanting a robust, affordable AK with rails for modern accessories, as well as a dependable spare rifle for friends and family.
Please note: Check the product images and listing for the battery, charger and magazine supplied with this version. Always wear suitable eye and face protection and check site power limits before play.
