Description

Our current batch of CYMA Sport AEGs are supplied with a USB Charger and an 8.4V 1100mAh NiMh Battery. While these items are perfectly functional, we recommend using a 7.4V 1300mAh LiPo battery and a LiPo Balance Charger for faster charging times, a longer lasting battery and improved peformance. A brief reminder never to leave your battery on charge unattended and always use a Battery Safe Charging Bag

The rifle is front wired, and the battery is stored in the handguard, leaving plenty of space for larger batteries. To release the lower handguard to fit the battery first turn the mock locking screws until they are horizontal, when they both pop outwards slide the handguard slightly forwards and it will drop downwards.

This handguard is a close replica of the legendary Arms SIR rail system, and has a unique look, making it unlike anything else out there on the battlefield. 20mm Picatinny rails are available at the 3, 6, and 9 o'clock positions, and the top rail is monolithic, allowing for longer optical sights to be mounted, and even red dot sight magnifier combinations!

The top of the rifle features a full length top 20mm RIS / RAS Rail for attaching Sights and Scopes, and the side of the rifle features a sling loop which matches up with the rear sling loop to allow for the use of two-point sling setups.

This AEG features an adjustable hop-up unit which allows spin to be applied to the BB which adds range and accuracy to the rifle. The stock is adjustable, allowing it to be set to 6 different lengths, meaning the rifle can be used by a range of user sizes. This rifle is perfect for those Airsoft Skirmishers who are looking to get into Airsoft, and are wanting a budget beginner rifle which looks a little different and stands out from the crowd.

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.

FPS, Power and Joule Limits can vary from site to site, so please get in touch with where you're going to play with in advance to avoid disappointment.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, with a 350fps limit for Automatic Replicas, 400fps for Semi-Automatic Replicas, and 500fps for Bolt Action Replicas.

Tap the tabs below to open the relevant chart for your replica.

This table should be used for reference, and cannot be used to check one weight against another, as the weight of the BB affects the power.

In order to check if the BB can be used with your replica chronograph using the weight you wish to use and then compare it against the table.

Every time you change weights you will need to re-chrono and check against the table. This is not a conversion chart between weights.

Suggested limits are based on Joulage Limit rules used Halo Mill: Proving Grounds, and is the equivalent of 350fps, using 0.20g BB resulting in an upper limit of 1.14j.
