Description

This Airsoft Electric Gun is designed around the AR/M4 design and features familiar controls to anyone who has used the platform before, and comes stuffed with a load of features which you normally wouldn't see from an out of the box AEG at this price point, making it a fantastic choice for those getting into the sport, or wanting a cost effective backup. 

The front of the AEG has a 14mm CCW Thread underneath the Bird Cage Flash Hider which will allow you to install Suppressors, Tracer Units, Muzzle Brakes and more. Simply unscrew the grub screw from the Flash Hider and twist to remove. The high density Nylon Fibre Handguard is a M-LOK design which offers a lightweight and tough platform to attach adaptors or M-LOK compatible accessories The Handguard also has a slot for a QD Sling Socket to attach, allowing you to quickly release a Sling once you have installed a compatible loop. The Top Rail runs the full length of the Handguard and down to the back of the Receiver, which is ready for Sights and Scopes to attach, and is also where you will find a set of Flip Up Ironsights which can be removed if you don't want them. At the rear of the Receiver you will notice an Ambidextrous Sling Plate, which means that you can attach a Sling from either side of the Gun, depending on whether you're Left or Right Handed. The stock is a Sliding Crane Stock design and houses your Battery, connected to a Deans Connector. To access the Stock, simply squeeze the tabs on the Butt Plate and pull it away as well as the blanking plate underneath. We recommend either a 9.6v 1600mAH NiMH Crane Battery or 7.4v <2000mAH Crane LiPO Battery for the best fit.

Deep inside the CYMA CM.623 there is a MOSFET to protect the Electrical Components of the AEG, as well as a Microswitch Trigger which is very pleasant to use. The benefit of a Microswitch Trigger is much faster response from the gun, as well as removing the chance of burnt-out Trigger Contacts from a traditional design. The gun has a Quick Change Spring system which lets you change the Main Spring in seconds, once the Gearbox has been removed from the Receiver. This is an amazing feature for Airsofters who play at lots of different sites with varying Power Limit rules, and need to quickly change the FPS of their gun. Please note that technical skills are still required to remove the Gearbox from the gun. The gun has an Adjustable HOP Unit which will apply backspin to your BBs, and potentially increase effective range when combined with a Heavyweight BB (0.25g+) and the correct settings on the Adjustment Wheel. To make changes to the HOP, pull back the charging handle and look inside the dust cover to access the Adjustment Wheel.

Included in the box is an Alloy 300rnd High Cap magazine which is filled from the top via the fill window and wound from the bottom with the clockwork wheel to feed BBs. If you're looking for the ideal starter gun to get you on your way to Airsoft skirmishing, and/or are looking for fantastic value out of the box, then the CYMA CM.621 is just that.

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.

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.
