If you're just starting your Airsoft journey and looking to get involved without spending too much, you're in safe hands with the CYMA Sport Gen.2 CM.513 M4 SD RIS AEG! This battery-powered AEG is made from ABS polymer with an alloy outer barrel and an upgradable version 2 gearbox. This makes the build light and easy to move with while staying competitive on the field, ideal for younger skirmishers or those after a lightweight primary for “easy mode” fun!

The proven alloy version 2 gearbox features robust steel gears, a type 2 cylinder, and reinforced polymer compression parts. Also inside is a 6.04mm tightbore inner barrel and an adjustable HOP-up unit, giving you above-average accuracy. This, the “Gen.2”, features the CYMA V2 MOSFET system, preventing trigger lockups while boosting trigger response, and a quick-change spring guide for easy power tuning.

On the outside, the CM.513 is equipped with an integral suppressor, giving it stealthy looks with a hidden extended inner barrel for enhanced accuracy. Its RIS handguard and railed receiver make it ready to be customised with 20mm Picatinny accessories such as red dot sights, scopes, flashlights, lasers and grips. The set even includes 2 x 300 BB high-cap mags, giving you ample firepower right out of the gate.

If you need a low-profile pair of ballistic glasses, these are for you! The PYRAMEX Anti-Fog Itek® Ballistic Eyewear has a rubber nose piece, providing superior comfort when it's time to equip these safety specs. The 9.75 base curved lens provides side protection without any seams or side shields.

  • 1300 mAh
  • 7.4V 2S LiPo
  • 25C Discharge rating

This LiPo battery from Gens Ace is designed to fit into flat and long battery compartments, such as those found inside the handguards of an AR36 or SMG-5. The battery connects to your AEG via a Deans connector (aka a T-Plug) and provides 1300mAh capacity with a 25C discharge rating. The battery is coated with heat shrink to prevent abrasion damage to the cells, and has a wire length of approximately 8cm, allowing some flexibility when squeezing the battery into small spaces. This battery would be great for any Airsoft gun which requires a 7.4V LiPo, but would also be of use for R/C vehicles, Drones or other electronics hobbies.

Description

The Package

The CM.513 M4 SD AEG is a lightweight polymer battery-powered M4 rifle 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.513 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. 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 the battery included with the CYMA Sport. The included battery charger is simple and safe to use, especially when paired with the included Battery Safe Charging Bag.

Delta Armory's 0.25g BBs are some of the best BBs on the market, great for both indoor skirmishes at close range, outdoor engagements or long-range target shooting. Being a bag of 1KG 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

  • Ready to play: Includes battery, charger, BBs, and a High-capacity mag - No need to buy extras to get started.
  • Easy to upgrade later: Standard Tokyo Marui spec parts and a Version 2 gearbox make future upgrades straightforward and parts easy to source.
  • Good accuracy out of the box: Tightbore barrel + Rotary HOP-up + 0.25 g BBs = Better groupings, range and efficiency for typical outdoor/indoor play.
  • Light and robust: Fibre reinforced polymer keeps its weight manageable for long skirmishes while being scratch-resistant and tough enough for regular use. Add a metal body later if you want more realism.
  • Customisable: 20mm Picatinny rails let you add a sight, torch or foregrip easily, without special tools.
  • 12-Month Warranty: We've got you covered for faults within the first 12 months of use. Find out more in our Warranty Terms and Conditions.

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 Deans connector to the one on your battery. Your charger will cut off when your battery reaches capacity, but you should never leave it on charge unattended. Using the included Battery and Charger, the charge time is approximately 6 hours. Use the formula below to calculate charge time for different batteries:


(Battery capacity mAh / charge rate mA) x 1.5 = Hours to charge

  • 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 butt plate from your stock by pressing the tabs on either side at the "toe" of the stock, pushing the tabs through to the rear, then lifting it free. Inside the central tube, you'll find the Deans connector. Position each of the cell groups of your battery inside the tubes on either side of the stock, then connect the Deans connectors. With your wiring neatly tucked in, replace the butt plate.
  • 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 1450mAh LiPo battery and charger for the CYMA CM.513 AEG.

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.

Currently own a CYMA CM068 and bought this as a back up. Considering this platform is from their sport range, the build quality for the price is spot on. Chrono test states 402 fps from the factory, so will be looking to change the spring to make it site legal. Will be adding a few metal parts in the future (metal sling plate and mag release) and will be mainly using it to practice my tech skills.
