CYMA M4A1 RIS Convertible 10.3 / 14.5 AEG Rifle Black
This CYMA M4A1 RIS AEG is listed as convertible between 10.3 and 14.5 inch configurations, giving you two rifle lengths in one. The shorter set-up suits close quarter games, indoor sites and woodland with heavy cover, while the longer one gives the classic M4A1 carbine profile for open fields and a more traditional look.
CYMA is one of the best-known names in affordable airsoft electric guns, with a reputation for solid, dependable rifles that are easy to maintain and upgrade. The M4A1 RIS pattern, with its rail-covered handguard, is one of the most popular airsoft layouts of all, and makes it easy to fit optics, lights, grips and lasers.
Two lengths in one
The names 10.3 and 14.5 are the barrel lengths in inches of well-known M4-style carbine configurations. Being able to switch between them means you can match the rifle to the site you are playing, rather than buying two rifles. Please check the product images and the instructions supplied with the rifle to see exactly which parts change between the two set-ups.
How an AEG works
An AEG (airsoft electric gun) uses a rechargeable battery to power a motor, which turns a set of gears inside the gearbox. The gears draw back a piston against a spring and then release it, and the rush of air pushes the BB through the hop-up and down the inner barrel. AEGs are the most popular type of replica because they are consistent in all weathers and cheap to run, with no gas to buy.
Getting started
Before your first game, charge a suitable battery fully, fit it as the manual describes and connect it carefully. Load a magazine and start with the hop-up turned off, then fire a few shots at a safe backstop and add hop a little at a time until the BBs fly flat without rising at the end of their flight.
The RIS handguard gives you rail space all round for accessories. Fit a sight first, zero it, then add a light, grip or laser to suit the way you play.

Compatibility
CYMA M4-pattern AEGs generally accept standard M4 AEG magazines, but fit between brands can vary, so test any new magazine before relying on it in a game. Use good quality seamless 6mm BBs. The listing does not state which battery type or connector the rifle uses, so please check with us before buying a battery.
Care and maintenance
Take the battery out after every game and store it away from the replica, and charge LiPo batteries only on a proper balance charger that you are supervising. Clean the inner barrel with a cleaning rod and a dry patch every few games, as dirt and broken BB fragments are the main causes of flyers.
Use good quality seamless BBs of a consistent weight, check external screws and accessories before each game day, and store the replica somewhere dry. Leave internal gearbox and electronics work to someone experienced with AEGs.
Who is it for?
This rifle suits players who want one AEG that can be set up for close quarter play or for open woodland, and anyone looking for a dependable, easy-to-upgrade M4A1 at a sensible price.
Please note: The listing does not say whether a battery, charger or spare parts are included, so please ask us before ordering. Always wear suitable eye protection when using any airsoft replica, and have it chronographed at your site before play.
