  • Handguard Battery
  • Pneumatic Blowback
  • Ambidextrous Design

A Pneumatic Blowback Airsoft 6mm BB Gun, designed and based on the MP5 used by various Military and Security Forces around the world, and made famous in Britain by the SAS. 

Full description


The weapon is constructed with an Alloy Upper Receiver, Outer Barrel, Stock Arms, and Internals, with a Polymer Lower Frame and Handguard. This weapon is part of G&G's GT Advanced TGM Blowback Range, meaning that every time the weapon is fired the weapon will impart force on the user to simulate the feeling of Recoil. This weapon is one of a kind, featuring a unique type of battery system, where the Handguard IS the battery. The removable Handguard features an integrated 11.1v LiPo System, which can then be removed for charging, and placed on the included Smart Charging Stand until it is ready to use again, and the package for the weapon even includes two batteries. The weapon features an Adjustable Linear Hop-Up unit, designed to add range and accuracy by adding Spin to BBs, and is fully adjustable allowing the use of a range of BB weights. The top of the weapon features adjustable Ironsights which feature Four Sight Modes, and can be fully adjusted for Windage and Elevation via the Back Sight Post. The weapon features an adjustable stock which locks into place, allowing the stock to be shortened for the most compact CQB Situations, and then extended for Outdoor Play. The weapon features multiple front and rear sling mount points, with Metal Rear Sling Loops making it perfect for Single Point Sling Setups. The weapon is fully Ambidextrous, allowing the weapon to be used by both Left and Right Handed Shooters, and is also great for transition drills which are a must in tight and compact CQB spaces. The outer barrel of the weapon features a 14mm Counter Clockwise Thread, allowing a range of Suppressors and Tracer units to be fitted, and comes fitted with a Thread Protecting Nut to protect it from damage. To attach Sights and Scopes to the weapon an MP5 Claw Mount can be fitted allowing the use of Holographic and Red Dot Sights. This is the perfect purchase for any Beginner or Intermediate Level Airsoft Skirmisher, allowing you to play without any of the hassle of traditional battery chargers, allowing you to simply remove the handguard and pop it in the charging stand, with simulated blowback to boot.
