Description

This electric Airsoft replica of one of the most widely used and iconic weapon platforms in use today. However the CM.518 features a custom muzzle break design for a unique style and functionality. The rifle's receiver, stock, buffer tube, handguard and sights, are built from tough but extremely lightweight polymer, with an reliable alloy barrel and internals for accurate and reliable shooting.

Unique to the CM.518 is the custom muzzle break compensator attached to the front handguard, giving it a mean aggressive look, but more importantly, allowing for a whopping 21" of 20mm RIS / RAS rail, as well as two 3'' and a bottom 3'' rail systems at the very front of the rifle, and M-LOK functionality on the sides of the handguard. This gives the M4 an insane amount of customisation options, be they sights, scopes, torches, lasers, PEQ units, you name it, this gun will probably accommodate it. However, later on down the line the muzzle can be removed by releasing the two screws at the front of the rail, allowing the compensator to be simply pulled off to reveal a 14mm CCW Thread and standard M4 / AR Flash Hider for attaching Silencers and Suppressors. 

The rail continues on to the body of the rifle to give it that cohesive and monolith look as well as giving you the option to equip a different sight at a later date.

In order to best replicate the real world M4, the body of the rifle features a dummy bolt catch and opposed to the original this Airsoft replica is constructed from lightweight, but dense polymer, allowing you to easily maneuverer around the field. The fire select is for right handed use and is easily switched between modes with the thumb, with the mag release on the right hand size of the gun easily accessed with the trigger finger.

Included is a classic style STANAG magazine is a 300rnd high cap magazine, easily wound from the bottom of the mag to keep you shooting full auto for extended periods of time.

By pulling back the bolt catch, the internal Hop-up unit is revealed, adjusted by turning the gear, giving you the option to set the BB spin, adjusting for windage, elevation and range.

The stock of the M4A1 can be adjusted at six locking points, allowing you to adjust the weapon between 70cm - 80cm, for a more comfortable shoulder weld, depending on your size. The butt plate of the stock is made from rubber, providing a slip free surface when using the rifle.

This rifle is rear wired, which means that the battery connector is accessed by simply pull the adjuster tab on the stock down and sliding the stock off to reveal the buffer tube, and Tamiya connector. A wider range of batteries can be used, such as crane stock batteries in the stock itself or Li-Po which fit down the buffer tube. We recommend 8.4v NiMh Crane Stock Battery or 7.4V 1300mAh 15C LiPo Stick Battery

The tightbore barrel is a sweet addition in that it allows for greater accuracy and range, able to hit those far away targets than other M4's that lack this feature.

This is the perfect starter weapon for those wanting to get into skirmishing and start playing. With it's tough lightweight design, it's a great choice for those run and gun speedy players, looking for something that will perform in both a CQB and larger scale environments. The weapon comes with everything you need right out of the box, allowing you to get stuck and start taking objectives and downing opponents. With a huge array of potential improvements thanks to the 20mm quad rail system, you can customise to your hearts content going forward. A cheap and easy way to start playing, the CM.517 has something for every new player.

Special Instructions

Please note that the Rear Sling Plate is made from plastic, and the rifle sling is basic, and is for looks. Should you want to use the rear sling plate it is suggested that you replace it with a Metal Version, such as the: NUPROL M4 Sling Plate AEG, and a heavy duty sling such as the NUPROL One Point Bungee Sling. Should you need help fitting these parts you can give us a call on: 01484 644709.

The Rail Integrated Compensator is removable by first removing the screw on either side, and then pulling off carefully by hand. This reveals a 14mm Counter Clockwise (CCW) Thread, which allows the attachment of Silencers, Suppressors and Tracer Units.

Occasionally cheap batteries and chargers are provided with AEGs, but this will vary depending on batch. These batteries can often be of low quality and are considered free gifts and will not last as long or provide as much performance as other batteries and chargers we sell. We recommend that you assume these are not going to be present in the box, and purchase an aftermarket battery and charger and if they are included, keep the free battery and charger as a backup. The correct battery for this AEG is as follows: NUPROL 9.6v 1600mAh Ni-Mh Crane Battery, and NUPROL Compact LiPo / LiFe / NiMh / NiCd Balance Charger
