ARES - OCTARMS Tactical 9'' Keymod Handguard Set - Black is a Keymod Hand Rail System made for Airsoft M4/15/16 AEG Rifles, which allows for maximum customisation of Weapons. The Hand-Guard is constructed from 6063 CNC Aluminium Alloy, giving it a nice clean and edged finish, and comes with the required Barrel Nut and Spacers. The package comes with everything you need to attach the Rail System to your Reciever, including Nut Spacers, Screws, and the Barrel Nut itself. This handguard is designed as an easy to install upgrade for your rifle, which is designed to be ergonomic and durable. KeyMod is a universal system for Firearms accessories, and is designed to be superior to the MIL-STD-1913 accessory rails, allowing the user to quickly attach and detach attachments, whilst still providing a solid lock with the Handguard itself. The handguard can be used to attach a variety of attachments, such as Lights, Lasers, Grips and Rail Covers. The Rail features KeyMod Slots on the Bottom, Left, and Right of the rail, giving plenty of space for attachments. The top of the Rail features an additional full-length 20mm RIS / RAS rail which can be used to add a full length top rail to your rifle allowing the use of a wide range of Long Sights and Scopes. This is the perfect purchase for any Airsoft Skirmisher who wants to give their weapon a new lease of life, or make it look like a completely different weapon, wilst at the same time adding extra functionality.
