Love recoil, but hate gas, and bored of low powered blowback? No problems, weak and unreliable blowback is a thing of the past with the new Centurion Arms CM4 C4-10 ERG Recoil Assault Rifle. Featuring the KWA Electronic Recoil Blowback System this rifle has been designed by PTS to not only deliver power, but to feel as close to the real thing as possible, and be tactically adventitious.

Full description


Lovingly kitted out with PTS Syndicate this rifle features all the best of PTS's Enhanced Polymer range, coming with the EPM Stock, Pistol Grip, Advanced Ironsights and Pistol grip meaning its good to go right of out of the box. No need to gather aftermarket parts and fit them, this rifle comes pre-fitted with the highest quality parts already fitted.

Internally the weapon was built by KWA, using their ERG Recoil System, which not only features heavy hitting recoil but also has a functional Empty Stop Fire system which means that the weapon will stop firing when the magazine is empty. The weapon also features an adjustable Hop-Up system for range and accuracy and is adjustable by a large radial system rather than the traditional gear system which makes it easier to fine tune the amount of hop you require. The weapon is also rear wired to allow battery to be stored in the Stock. The weapon also features an ambidextrous fire select making it easier to change fire mode when transitioning between shoulder in CQB environments.

The front of the weapon features the 10'' PTS Centurion Arms C4 Four Point 20mm RIS / Ras Railed Handguard which is constructed entirely from heavy duty alloys making it tough and durable. Thanks to the choice of 20mm RIS / RAS it also means that you have access to a wide range of aftermarket parts and accessories which can be attached to the Top, Bottom, Left and Right of the handguard. This means you have the potential to create a huge array of weapon setups, and fine tune your loadout to match the scenario you will be playing.

This rifle is perfect for those Airsoft Players who are looking for a rifle which is not only highly realistic, but already comes pre-fitted with all the best PTS Syndicate parts available on the market today. If you're a fan of recoil, but not a fan of gas, then this rifle is for you. Keep on playing for longer without having to stop to re-gas your mags every half hour!

The externals of the replica are metal where they would be on the real world gun. This includes things like the outer barrel, handguard, and receiver. If a real world gun has polymer parts then the gun will still be marked as full metal externals, examples of this would be an M4, where the Stock and Pistol grip are always made from Polymer.
