Product Information

The SR4 A1 sportline AEG or airsoft electric gun is modelled on the famous special ops military spec M4A1 carbine machine gun or assault rifle, and this airsoft replica is manufactured by SRC Airsoft in Taiwan for Bulldog Airsoft UK. This M4A1 replica AEG gun is supplied as a full size and weighted version, and the gun has been carefully balanced in UK legal two tone blue and black colours, so that the main body is black and the barrel surround, tactical stock are legal two tone blue. The SR4A1 has an ergo friendly ambidextrous design suitable for both left and right handed users, and with its adjustable tactical stock the SR4A1 has a full length of up to 850mm. The carbine replica has an internal steel barrel which adds to the guns body weight for increased sturdiness, which also provides the shooter with a realistic feel to the gun. The M4A1 can fire in semi auto and fully automatic firing modes, and this gun has a durable hi-torque sports-grade metal and resin gearbox and hi-spec electronic motor which ensures a fast rate of high velocity shooting, which is stated by the manufacturer as 330fps with 0.20g and higher with 0.12g. The gun is supplied with a winder based starter magazine that will hold approx 50 x 6mm rounds (hi-cap upgrades available). Effective range is about 60 metres, and the SR4 A1 features an internal SPIN UP firing system for increased accuracy and firing distance. The SRC M4A1 replica is supplied with a long life re-chargeable battery and UK mains charger. We recommend only using polished hi-grade BB 6mm pellets with this AEG rifle.

IMPORTANT: The HOP-UP is located behind the dust cover as normal, but is not on a spring, so you will need to pull the dust cover down by hand to adjust hop-up.
