Description
The Package
The CM.508 M4 S-System AEG is a lightweight polymer battery-powered M4 replica with semi-auto and full auto fire modes. It's based on the Tokyo Marui M4 internal design, meaning aftermarket upgrades are plentiful, as are parts for repairs and customisation.
With 20mm Picatinny rails on the handguard and receiver, the CM.508 is ready for any 20mm Picatinny accessories you choose to mount, including red dot sights and scopes, vertical and angled foregrips and even lasers and flashlights for CQB scenarios. The barrel is also threaded to 14mm CCW, meaning you can add a tracer unit or suppressor if the mission requires it. We've been very impressed with the performance-to-price ratio of the CYMA Sport series, and while they may be cheaper than alternatives, they are still competitive in game!
The included 7.4V LiPo Battery will improve trigger response, rate of fire and longevity when compared to 8.4V NiMh batteries. The included LiPo balance battery charger is simple and safe to use, especially when paired with the Battery Safe Charging Bag.
Delta Armory's 0.25g BBs are some of the best on the market, great for both indoor skirmishes at close range, outdoor engagements or long-range target shooting. Being a bag of 1KGs worth, you should be able to get quite a lot of trigger time in before you need to reload, even if you've got a heavy trigger finger!
PYRAMEX' Anti-Fog Itek® Safety Glasses are easily capable of withstanding Airsoft projectiles and keeping you safe while you shoot. We do, however, recommend getting a lower or full face mask if you're planning on attending skirmishes.
Built to make Airsoft more affordable than ever before, this Airsoft beginner bundle includes everything you'll need to get started with safety as a priority!
Why you'll love it

Quick Start Guide
- Charge your Battery: Place your battery inside your Battery Safe Charging Bag. Next, plug your charger into a 3-Plug UK wall socket and connect the Balance connector (small white connector) to the corresponding socket on your LiPo balance charger. Some balance chargers also require you to connect the power cable (Deans or Mini-Tamiya). Your charger will cut off when your battery reaches capacity, but you should never leave it on charge unattended.
- Load your magazine: Open the feed hatch on the top of your High-cap magazine. Pour BBs in until full.
- Wind your magazine: Wind the wheel on the bottom of your magazine 5-10 times or until the noise changes and the wheel becomes firm.
- Put on your Eye Protection: Safety when using Airsoft guns should be your number 1 priority. Always wear eye protection before loading your AEG and ensure any spectators are also protected.
- Connect your battery: Remove the lower handguard by turning the polymer screw-style locks on each side by 270 degrees (to the rear of the side rails, next to the small embossed padlock symbol). When this is done, the mock screws will lift under spring pressure and allow the lower handguard to slide forward. Inside, you'll find a male Deans battery connector. Connect this to the female Deans connector on your battery.
- Insert your magazine: With the fire selector switch set to "SAFE" and the barrel pointed in a safe direction with your finger off the trigger, insert your magazine by pushing it up into the magazine well.
- You're now ready to shoot! - Never shoot at animals or humans who aren't in an Airsoft skirmish

FAQ
Q: What Ammo/BBs do I need?
A: You'll need 6mm plastic Airsoft BBs between 0.20g and 0.28g in weight. This bundle includes 4000 x 0.25g BBs, which is plenty for a full day of outdoor play or several short CQB sessions. Never attempt to shoot any form of metal ammo or "paint" ammo, as these are not designed for Airsoft AEGs and will cause internal damage.
Q: What battery do I need?
A: This Beginner Bundle includes the correct 7.4V LiPo battery and a LiPo Balance charger for the CYMA Sport Gen.2 CM.508 AEG. We chose a LiPo battery to provide the extra power required for the Gen.2 CYMA MOSFET.
Q: How old do I need to be to buy and use an Airsoft gun?
A: Airsoft guns can be legally purchased by anyone over 18, but can be used by anyone of any age. We recommend adult supervision for users under 14 years old, at the parents' discretion. Most skirmish sites have a minimum age of 14 or over for attendees, some of which require under-18s to attend with an adult.
Q: Can I buy this for someone else?
A: Yes, provided you are over 18 and either have a Specific Defence under the VCRA, or choose a "Two-tone" colour variant.
Q: Do I need a UKARA or a License?
A: Not necessarily. You’ll need a UKARA membership or other valid defence under the VCRA to buy realistic colours (Black, Tan, etc.). Two-tone options can be purchased without UKARA. There’s no license required to own or buy Airsoft guns.
Q: Does it hurt to get shot with this?
A: It can sting, similar to a rubber band snap on bare skin, but less than a paintball. The sensation depends on distance, clothing, and protective gear. Airsoft guns produce muzzle energy around 1/14th of the average Paintball Marker, so hits hurt far less than hits from paintballs.
Q: Is an Airsoft gun dangerous?
A: Only if misused. Airsoft guns must never be brandished in public or in an area visible from public land. When transporting an Airsoft gun, ensure it is unloaded and concealed in a gun bag or case. When shooting, both the shooter and any spectators must use eye protection. It is also important that you don't shoot at targets beyond your property boundary.
