Description

This Airsoft Electric Gun is powered by a Battery in the Stock, and offers both Semi and Full Automatic fire from a Two Stage Trigger. This means that a half-pull of the Trigger gives a single shot, whereas a full-pull of the Trigger results in Full Automatic fire. The Bullpup design of the Rifle as well as the CQB Barrel Assembly makes for a very short package at 66cm, but can still reach out and touch people thanks to a long Inner Barrel, due to the Gearbox being at the rear of the Rifle. This also makes for a well-balanced weight that is comfortable in the shoulder, and for long periods of time.

The main body of the Rifle is made from Polymer as per the real thing, with an Alloy Outer Barrel Assembly and Receiver to make the Rifle strong, and to give it a realistic weight. The Upper Receiver features an Integrated 1.5x Magnified Scope as the real thing does, which can be adjusted to ensure it aligns with your BB impacts. There are several 20mm Rail Sections around the Receiver which can be used for a variety of purposes, from Lasers and Lights to a Canted Red Dot Sight. The Integrated Foregrip is easy and comfortable to use, and can be folded to one of three positions. The Outer Barrel Assembly features an Alloy Flash Hider which is secured onto a 14mm CCW Thread. This Flash Hider can be removed to install your own Suppressors, Tracer Units and Muzzle Devices, just be sure to remove the Grub Screw from the Flash Hider first! The controls on the KU904 PARA are very easy to use, and most are ambidextrous (can be used from both sides of the replica) which makes it very good for left handed players. The Magazine Release and Safety can both be used from either side of the Gun. The KU904 PARA also features a Rotary HOP Unit which can be adjusted by pulling back on the Charging Handle and looking behind the Mock Bolt in the Dust Cover. The correct settings and BB weights will help you yield far better performance and consistency when shooting. A Front and Rear Sling Loop can be found on the Gun to help you carry it throughout the day. The rear of the Gun is where your Battery should be installed, and has just enough room for either an 8.4v 1600mAh NiMH Block Battery or a short 7.4v LiPo, connected to the Mini Tamiya Connector.

Included in the box is a 300rnd semi-transparent High Cap Magazine which is filled by opening the Fill Window and pouring BBs in. Once it is full, wind the bottom of the Mag to start feeding BBs and place it in the Gun. If you're looking for something a little different from your run-of-the-mill M4, that is happy in both CQB and Outdoor engagements, then the Army Armament KU904 PARA is just right.
