The Marui Boys M4A1 9.0V is a reduced-size airsoft electric gun designed to be lightweight and easy to handle. Built at approximately 70% scale, it retains the familiar AR-style appearance of the M4A1 while keeping the weight down to just 885 grams.
The gun runs on six standard AA alkaline batteries, eliminating the need for a separate airsoft battery and charger. The batteries are housed inside the front handguard. Both semi-automatic and full-automatic firing modes are available, with the full-auto mode delivering approximately 15 rounds per second.
An adjustable hop-up system helps stabilise the BB's flight and allows the hop setting to be matched to the ammunition. Tokyo Marui recommends lightweight 0.12 g 6 mm airsoft BBs for this model. With a muzzle velocity of approximately 45 m/s, the Boys M4A1 operates at considerably lower power than a typical full-size AEG.
The body is primarily constructed from ABS plastic, with details that retain the recognisable appearance of the M4 platform. A four-position retractable stock allows the overall length to be adjusted to suit the user, while the adjustable rear sight provides straightforward sight alignment.
A push-button safety is positioned at the front of the grip. The gun can only fire while this button is pressed, providing an additional safeguard against accidental firing during handling.
The Marui Boys M4A1 is a practical option for users looking for a lightweight, compact and easy-to-operate M4-style AEG without the need for a separate rechargeable battery. The package includes the airsoft gun, magazine, protective cap, instruction manual, cleaning rod and 100 rounds of 0.12 g BBs.
