GT Advanced version of the M4 platform, equipped with SOPMOD stock, MOSFET and featuring EBB. Also contains a quadrail handguard, down grip and four 120-round mid-cap magazines.

Some signs of wear around the fire selector switch and front rail. Although the gun fires fine on semi and full auto, it sounds like the anti-reversal latch is slipping occasionally, so it will need replacing. I've taken £50 off the asking price to cover the cost of the gun being serviced and repaired.

£125 including Parcelforce express48 delivery.
