Ever wanted a rifle pistol based on the AR Platform, but which is classed as a pistol by the National Firearms Act in America? Though not an issue for Airsoft ARES have developed their own version of the AR-15 Pistol and Arm brace for those who love the look.

Full description


Originally designed for real steel use the AR-15 Arm brace was developed to help disabled shooters to have better stability when using their rifles, but became popular in America for those who which to avoid restrictions on Rifles by having the weapon classified as a pistol due to loopholes in the law, and became somewhat of a joke. The pistol brace is now popularised in the US for home-defence and for hunting.

The Airsoft replica itself is part of the ARES M45 S-Class Series of rifles, a range of Airsoft replicas which feature an AR / M4 style receiver which has been modified to accept pistol caliber style magazines, for those who want a more unique type of M4. The rifle pistol is constructed externally with an alloy handguard, outer barrel, and internals, with a polymer pistol grip, receiver and rubber arm brace. 

The replica features the ARES AMOEBA Stabilizing Brace Stock, which features a PDW Style sliding mechanism allowing the brace position to be adjusted, with a rubberised clamp which flexes to any arm size, and is affixed using the supplied velcro band, for a quite unique look. In addition to the stock the weapon comes with ARES new realistic sized pistol grip thanks to their specially developed motors which are lower profile removing the need for the fatter pistol grips commonly seen on Airsoft replicas.

The frontend of the pistol features a four point 20mm RIS / RAS rail, the most common type of attachment type in Airsoft, allowing for a wide range of aftermarket forgerips, torches, lasers and more to be affixed to the weapon. The top rail of the weapon also perfectly matches up with the handguard allowing for larger sights and scopes to be used, as well as more complex holographic and magnifier setups. The replica also features a threaded outer barrel for attaching suppressors and silencers, which is threaded with a 16mm Clockwise thread to allow for ARES brand suppressors to fit, or other brands with an adaptor.

The weapon features an adjustable hop-up unit which is designed to add range and accuracy to shots by adding a small amount of spin to BB before they travel down the barrel using a small rubber contact patch. This allows BBs to take advantage of the Magnus effect by displacing air to create a more stable flight path. The hop-up unit can be adjusted for a wide range of BB weights, and is accessed behind the mock bolt plate when the charging handle is pulled to the rear. The replica also features a V2 gearbox, allowing for a wide range of upgrades and spare parts, and is rear wired with the battery stored in the mock buffer tube.

This rifle is perfect for those Airsoft skirmishers who are looking for an Airsoft replica which will attract attention, for those who want to be followed by the ATF, or for those who want a weapon which looks unique, but also features all of the great features of the AR / M4 platform.
