SKU: CM.079B(JD) BK / 742521031414


CYMA is bringing the goods with the CYMA CM.619 Fatboy 12'' Metal M4 AEG Gel Blaster!

The CYMA Fatboy 12'' is an AEG m4 gel blaster that is made from Metal- This blaster is the perfect in between weight for realism and differing play styles.

The front of the blaster features an absolutely massive 'Fatboy' KeyMod Rail System that lets you attach rails and accessories at all angles and positions, saving you weight where a rail isn't used. The top of this rail system features an alloy 20mm rail for the addition of optics (or any other 20mm accessory), as almost all scopes you will want to use attach to this kind of rail system.

The blaster also features Alloy in the places you need it such as the Handguard, barrel and unique looking flash hider, the buffer tube, top rail, fire controls and rear sling plate - basically all the areas where the rifle will take stress. The receiver is also finished in metal. The flip up iron sights work incredibly well and feature a sight and precision sight depending on your needs in the field, the stock is an adjustable VLTOR styled stock to complete the look. Finally there is an ambidextrous magazine release for those that need it, and the fire selector whilst not ambidextrous is smooth and feels great to use. 

Do not upgrade any part of your toy gel blaster as this will void the warranty. Upgrades refer to pulling any of the blaster apart or opening it up, changing springs or upgrading the battery from 7.4v to an 11.v battery.
