This high end AEG from ASG is modeled after the CZ 805 BREN assault rifle which has been in use by the Czech armed forces since 2010. The airsoft version features a full metal aluminum alloy top receiver and a reinforced polymer lower with official CZ trademarks. A monolithic top rail runs along the entire top of the rifle allowing plenty of space for mounting optics. Front and rear flip up sights are included with the rifle. The sights can be removed if necessary. The length of the stock is adjustable to fit the user's preferences. It can also be folded over and comes complete with an adjustable height cheek rest. The gun has several ambidextrous features including the fire selector, sling mounts, mag release, and charging handle. There are a total of four mounting points for one or two point slings.
Separating the receivers for maintenance is very easy on the CZ 805 BREN. Simply remove two pins and they slide apart. Removal of the stock allows easy access to the quick change spring system and access to the battery compartment. The quick change system makes it easy to change out the spring to raise or lower the FPS of the AEG without having to disasemble the gearbox (additional springs sold separately). The high quality gearbox is full metal with a ball bearing spring guide. The gun is LiPO ready out of the box. The gun comes with a high capacity flash magazine and is compatible with most M4 type magazines.
