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 CM.513 M4 SD RIS AEG! A proven platform made even better in its latest iteration, the CM.513 is part of CYMA's "Sport" line, rocking a lightweight and handy build with no performance compromises, ideal for those with less physical strength or those who like to conserve energy!

The alloy version 2 gearbox inside the CM.513 is equipped with 18:1 standard ratio gears running on 8mm steel bushings, a type 1 cylinder, reinforced polymer compression parts and a quick change spring system. Also inside is a 6.03mm tightbore inner barrel and an updated rotary HOP-up unit, giving you above-average accuracy potential and the latest HOP-up unit design for M4/AR-15 AEG platforms. All internal parts are standard Tokyo Marui AEG spec, meaning the sky is the limit when it comes to upgrades later down the line!

Externally, the CM.513 is inspired by real-world integrally suppressed M4/AR-15 rifles designed for stealth in a close-quarters environment. The handguard is a 20mm Picatinny quad-railed example, ready for vertical or angled grips, lasers or tactical flashlights. The receiver is also railed and ready for a red dot sight or scope but comes with flip-up iron sights to get you started. If you've been searching for an affordable, reliable and well-equipped Airsoft primary for your first foray into the sport, the CYMA CM.513 M4 SD RIS AEG is one of the best options out there!

  • For NiMH or NiCd/NiCad batteries
  • Suitable for 8.4V & 9.6V batteries
  • Mini-tamiya connector

If you're searching for an affordable but reliable NiMH charger for Airsoft batteries, you're in luck! The Ghost 8-12V NiMH/NiCd Battery Charger; Mini-Tamiya is a simple NiMH/NiCd battery pre-wired to a mini-Tamiya battery connector, featuring an L.E.D indicator light which glows red during charging and turns green when charging is complete. 

The Ghost charger is capable of charging 8.4V, 9.6V and 10.8V NiMH and NiCd batteries and has a charge rate of 400mA/0.4A, making it a fair bit faster to charge than comparable simple chargers. You can find the formula to work out the charge duration for all compatible batteries in the "Full Description". 

As with all batteries and chargers, we recommend using a Battery Safe Charging Bag and never leaving a battery on charge unattended. It also goes without saying, but you should never attempt to charge any Lithium battery (LiPo, Li-ion or LiFe) using this charger. If you don't know why, trust us, you don't want to find out!

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 9.6v NiMH 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 Eyewear is 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 here

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 Mini-Tamiya 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 Mini-Tamiya connector. Position each of the cell groups of your battery inside the tubes on either side of the stock, then connect the Mini-Tamiya 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 9.6V 1600mAh NiMH battery and a NiMH charger for the CYMA CM.513 AEG. We chose a NiMH battery as they are more robust and user-friendly than equivalent LiPo batteries.

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. For more information on Airsoft Safety, check out our Safety Guide here

Joule Charts

Special Instructions

These table can be used as a reference to see if the BB weight you are using will be over acceptable Joulage limits at some Airsoft Sites in the UK. To check if the weight can be used chrono your weapon using the BB you intend to use, and then compare it to the chart.

Very disappointed.. went use it for the first time, shot about 10 bb’s and the. Stopped working. Tried a number of different batteries, mags etc. Been playing for about 15 years and never had this happen. I had painted the riff so can’t return it. Turns out it’s the motor. I had a spare one luckily. Not patrol bases fault, they have great service etc. just disappointed in the rifle.

Great gun, one of the cheaper ones, but still has a sleek style and distinctly simulates a real firearm in terms of function and weight. Photo displays CYMA CM.513 M4 SD RIS AEG compared to my old rifle. 10/10 recommend
