Cyma AK Beta CQB (Black – CM521)
The Cyma AK Beta CQB (CM521) is a compact electric AK in the style of the short Beta Spetsnaz rifles, finished in black. It keeps the classic AK lines and controls in a short, handy package with a rail on the shortened handguard, which suits close-quarters games and players who want an AK that is easy to move with.
Cyma is one of the best-known makers of affordable AEGs, and its AKs have a long reputation for being tough and straightforward to maintain. The CM521 is a sensible choice for newer players and a practical, low-cost AK for experienced players.
Build and handling
A European retailer listing for the Cyma CM521 describes a plastic body and mostly plastic external parts, a shortened handguard with a RIS-type rail and a fixed stock that houses the battery. It gives a length of 715mm, a weight of about 1.75kg and a 285mm inner barrel, which makes this a light rifle that is easy to carry all day.
The AK controls are familiar: the selector lever on the right side of the receiver, the paddle magazine release in front of the trigger guard and the rocking magazine fit. Check the product images for the exact rail and stock layout of this version.
Internals
The same listing describes a metal reinforced Version 3 gearbox on 7mm bearings with steel gears and a short torque motor, an adjustable hop-up and safe, semi and full-auto fire. Version 3 is the standard AK gearbox, so service parts are easy to find.
The listed magazine is a plastic high-capacity type holding 220 BBs. The retailer recommends a mini 9.6V battery with a Tamiya Mini plug for the stock compartment; check the size of any battery against the space before buying.

Compatibility
The CM521 takes AK-pattern AEG magazines; Cyma AK magazines are the safest choice, and most mainstream AK AEG magazines fit, though it is worth testing a spare. The rail takes standard 20mm accessories.
Version 3 gearbox parts suit the internals, but check with us before ordering upgrades. The retailer recommends a mini 9.6V battery with a Tamiya Mini plug; a compact 7.4V LiPo of the right size is a common alternative, but check the space and the connector first.
Care and maintenance
Take the battery out after every game and store it separately at a sensible storage charge, rather than leaving it connected inside the replica. Charge LiPo batteries with a proper balance charger, keep them in a LiPo-safe bag and never leave them charging unattended; NiMH packs should be charged with a smart charger that stops when the pack is full.
Run a cleaning rod with a lightly dampened patch through the inner barrel from time to time to clear dirt and residue, which keeps the hop-up consistent. Use good-quality seamless BBs, never reuse BBs that have been on the ground, and wipe the outside over after damp or muddy games. Leave gearbox work, shimming and spring changes to a competent technician.
Who is it for?
The CM521 suits newer players who want a light, affordable AK, CQB players who want something short, and anyone who likes the classic AK look in a compact package.
Please note: A European retailer lists the CM521 with a battery, charger, sling and cleaning rod; please check with us whether those items are included with our stock before ordering. BBs are not included. Always wear suitable eye protection, and full-face protection where your site requires it, when using or testing any airsoft replica.
