Description
Cyma 5.1 Hi-Capa Mosfet AEP Pistol (Lipo Battery and Charger Inc. – CM128S – Blue)
The Cyma CM128S is an electric airsoft pistol in the popular 5.1 Hi-Capa style, fitted with a MOSFET and supplied with a LiPo battery and charger. This is the blue version, a bright take on a pistol shape that is already a favourite for competition and skirmish use.
Hi-Capa pistols are known for their long, flat slide and comfortable grip, and Cyma’s electric version brings that shape to players who prefer the reliability of electric power over gas. With the battery and charger included, it is a complete package straight from the box.
Build and design
The CM128S is built from high-strength polymer, keeping it light and tough. A 20mm rail under the front of the frame accepts torches and lasers, and the Hi-Capa grip gives a secure, comfortable hold.
The blue finish makes the pistol stand out, and is a good match for players who like their kit to be a little different.
Performance and internals
The CM128S fires on safe, semi and full-auto, selected with its fire selector, and the hop-up is adjusted with a thumb dial, which makes it quick to set up. It feeds from a 28-round magazine.
The MOSFET helps protect the trigger contacts and gives a crisp response with the supplied LiPo battery. Because it is electric, the CM128S performs consistently in cold weather, when many gas pistols struggle.
Getting started
Charge the battery fully on the supplied charger before first use, and fit it as the manual describes. Load the magazine, insert it, and fire a few shots on semi-auto at a safe backstop. Set the hop-up a little at a time until the BBs fly flat.
Electric pistols are ideal for practice in the garden with a BB trap, and they are not affected by cold weather the way gas pistols are. Have the pistol chronographed at your site before using it in a game.

Compatibility
Spare magazines should be Cyma CM128-series AEP magazines; Hi-Capa gas pistol magazines will not fit. The 20mm rail accepts standard pistol lights and lasers. Holsters should be chosen to fit this pistol and any accessory on the rail. Use 6mm BBs; 0.20g BBs suit most AEPs.
Care and maintenance
Disconnect or remove the battery when the pistol is not in use, and charge LiPo batteries only on a suitable charger under supervision. Never leave a battery charging unattended.
Clean the inner barrel now and then with a thin rod and patch, use good quality seamless BBs, and keep the pistol dry. Avoid dry firing for long periods, and have any internal servicing done by someone familiar with AEPs.
Who is it for?
The CM128S suits players who like the Hi-Capa shape but want a sidearm that works in all weathers, as well as newer players looking for a complete, ready-to-use pistol package.
Please note: BBs are not included. Always wear suitable eye and face protection when using airsoft replicas.
