It also allows for attaching a big range of telescopic sights etc. The replica also features an adjustable collapsing stock with an anti-slip butt that has several different positions to allow it to fit most users in comfort. The outer barrel has at its end a 14mm left-handed thread that permits it for the mounting of a suppressor.
Access to the hop-up adjustment system is standard, (when you retract the cooking handle. Safety the fire selector is located on the left-hand side of the body.) At the core of this airsoft replica is a reliable, v.2 type metal gearbox with a set of steel gears, warped spring guide and 7mm bearings, That enables for more or less 360 FPS muzzle velocity, straight out of the box.
Shots fired from this CYMA rifle are precise and deadly accurate with a long-range due to the 300mm long inner barrel.

    An excellent aeg.
    This m4 has all the power of a more expensive m4.Fps is excellent,build quality is excellent and yes you get a battery and charger unlike some more expensive models.
    The rifle has a nice weight to it and has zero rattles and shakes.Does it look good in two tone blue??? YES YES YES.The rifle has a lovely paint finish on it and feels so smooth to the touch.From 20 feet it hits cans with a whollop and makes mince meat out of targets.A beautiful m4 from cyma with all the trimmings of a more expensive m4.Delivery was 2days and no damage at all to the outer packaging.
