Cyma CM517 M4 Short AEG (Sports Line – Black – CM517)

Build, Design & Ergonomics

• The CM517 features a polymer outer body — including the receiver, handguard, buffer tube, stock, and even magazine — which keeps the weight low (~1.8–1.9 kg) while maintaining durability.

• It sports a metal outer barrel, 14 mm CCW thread flash hider, polymer RAS/quad‑rail handguard, and both front and rear iron sights, ideal for accessory mounting.

• Includes a six‑position adjustable crane stock with rear sling plate and removable rear sight block for optics rail access

Internal Mechanics & Performance

• Powered by a Version 2 metal gearbox with steel gears, 8 mm bearings, reinforced spring guide, and high-torque motor—designed for reliability and upgrade flexibility.

• FPS runs around 300–350 fps with 0.20 g BBs—typically ~340 fps in UK spec models.

• Carefully engineered adjustable hop-up and tightbore barrel (~280 mm/6.08 mm) deliver respectable accuracy for the price range.
