Full description


The Cyber Gun FN Five-Seven is a seriously well constructed Gas Pistol replica of the legendary FN 5-7, a Pistol designed from the ground up to chamber the 5.7x28mm round, making it the go-to-choice for defeating Body Armour in the real world. 

The Frame and Slide are made from a high density Polymer which looks amazing, has a great finish to it and feels good in the hands. The Polymer slide also means that it cycles really efficiently, and makes a great noise when firing. This, coupled with the Gas Magazines that feature huge Gas Reservoirs, makes for an efficient Pistol which can hold its own in the cold. The Magazine is made from Alloy as you would expect, and brings the Pistol to a total 757g, which is actually more than the reported loaded weight of the real thing.

The Frame features a 20mm Pistol Rail, which is great for attaching Lasers, Lights and other accessories to hone your skills, and make you more effective on the Airsoft skirmish field. An Ambidextrous Safety can be found on either side of the frame, which will lock the Trigger in place and prevent the Pistol from firing. The Pistol Grip features excellent texturing which is comfortable to use both with and without gloves, and helps you maintain control over your Sidearm in the field. The Adjustable HOP is located on the Outer Barrel, which needs to be removed from the Gun to adjust. Remove your slide by pulling back the switch underneath Herstal on the frame. Remove the top slide and then separate the Outer Barrel from the slide, and look on top of the unit to find the Grub Screw adjustment for the HOP Unit.

The Magazine holds a total of 17rnds, and holds a tremendous amount of gas thanks to the dimensions of the unit. The body of the mag is made from Alloy, with a set of Polymer Feed Lips on top. The Magazine features faux round counters, a side-accessible follower and a 5.7x28 marking on the side.

Included in the box is the gun itself, a 17rnd Gas Magazine and an Instruction Manual. If you're looking for a legendary sidearm which is modern, cutting edge and has the performance to back up its' fierce looks, then the Cyber Gun FN Five-Seven is for you.
