Full description


Being lightweight and easy to operate, this M4 based electric Airsoft replica is ideal for beginners, those who don't want to break the bank or for those looking for a simple backup weapon to sling in the kit bag for when your main RIF fails. It has all the features you would expect of an M4 replica, such as a six position sliding stock to adjust for shooter comfort, a four-point RIS handguard which will accept any 20mm accessories, a 14mm CCW threaded outer barrel and a railed receiver, which is ideal for all your sights/scopes and other aiming devices.

The weapon is almost exclusively built from Polymer on the externals which makes it very light and easy to wield around the field (poet but didn't know it?). The inclusion of a free battery, charger and 300 round high cap makes this package even sweeter knowing that you can take it straight to the Airsoft field out of the box and have it running without extras. We will however point out that the free battery and charger are low spec and would be best replaced which a higher quality aftermarket pair.

The rifle features a four point 20mm RIS / RAS Rail System on the front of the rifle allowing a huge range of aftermarket attachments to be fit to the replica, with 20mm RIS / RAS being the most common type of Airsoft mount on the market to date. The bottom rail can be used for foregrips, bipods, launchers and more, with the sides for Torches and Lasers and the top rail for a PEQ box for the ultimate tactical look. The top of the rifle also features a 20mm RIS / RAS rail which is exposed once the top carry handle is removed allowing a huge selection of optics to be attached, ranging from red dots and holographics all the way up to scopes and telescopic sights.

This Airsoft Gun features an adjustable Hop Up unit which is designed to add range and accuracy to each shot. The hop-up unit works by adding spin to the BB by passing it past a rubber patch, this spin then displaces air around the BB to create an air pocket which stabilises its trajectory to add range and accuracy. The hop-up unit is fully adjustable to cater for a wide range of Airsoft BB weights and types. 

This RIF runs absolutely sweet for a budget priced CYMA M4, with a consistent read-out of 98m/s on the chronograph, and achieving a respectable 600RPM (Rounds Per Minute) on a 7.4v LiPO battery. When switching to full auto, the muzzle velocity hardly drops which is a sign of good compression and air seal.
