Product Information

The M4 assault rifle was developed and produced for the United States government. This Airsoft BB gun is a spring powered replica model and is manufactured by Wellfire, and is a full 1:1 size replica of the real thing. The MR733 is manufactured in black and two tone toughened ABS anti-shock resin plastic, which has been carefully balanced to comply with UK laws. The MR733 has an ergo friendly design suitable for both left and right handed users. With its adjustable shoulder stock fully extended the MR733 has a full length of 80cm. The MR733 has a steel barrel with a decent body weight for increased sturdiness, which also provides the user with a realistic feel to the gun. The MR733 has a single shot spring powered slide action cocking mechanism with a safety catch, which makes gun inexpensive and easily maintained; as it requires no gas or batteries to operate. The MR733 features a integral fixed HOP Up shooting system which will make the gun very effective in back garden target competitions. We recommend only using quality polished 6mm BB pellets with this assault rifle.

Please be advised that these guns are colour coded by us to UK legal two tone upon ordering. Delivery will be 3 to 4 working days after placing your order.
