Product Description

Remember we deliver air rifles & pistols straight to your door!

Full metal version of one of the most instantly recognisable assault rifles ever made, the M4A1 (sometimes called M4-A1 or just the M4) is a brilliantly made replica that fires 4.5mm steel BBs with high accuracy.

This gun is fitted with flip up sights but also has many accessory rails that makes the M4A1 able to be customised to suit your need. Scopes, lasers, grips and more will all fit to the picatinny rails of this M4.

All rifles come with FREE Double Screw Mounts RRP £18.95 when ordered with a Scope!
