Tanie Militaria got in stock the G&G CM16 Predator AEG that comes equipped with the ETU. Here is their take on this AEG... "The CM16 Predator carbine replica by G&G was made as part of the Combat Machine project , the aim of which is to provide high-quality replicas at a price that can be considered economical. Combat Machine replicas are characterized by the highest, characteristic for the G&G company, quality of workmanship and work culture as well as high quality of the materials used . The main factor that allows to reduce the price is the use of a body made of high-quality plastic instead of metal. It is also important that the body itself is made of glass - fiber reinforced plastic - just like the handguard or the stock, and almost all of the plastic elements. Made of metal and the outer barrel, stock guide, hooks, magazine casing and most of the small parts were made.

The replica is perfect for medium-range operations, due to the muzzle velocity of ~ 410 FPS. The used top RIS rail allows for the attachment of any optical sight device, while the telescopic stock, housing the battery, allows the replica to be adapted to the individual preferences of the user. The set includes a set of folding, mechanical flip-up sights .

In addition to the high-quality parts typical for G&G, GB has an innovative ETU (Electronic Trigger Unit) system installed  . The circuit completely replaces the contact block and complements the role of the MOSFET circuit. Thanks to the electronic operation of the trigger, the system has gained an excellent response to the trigger. Each time the trigger is pressed, the full GB work cycle is performed.

The ETU system has the ability to program fire modes. The user has basic access to the SAFE - SEMI - modes and a choice of FULL AUTO or a 3-shot series. Programming is very easy - just set the selector to the SEMI position and hold the trigger for about 10 seconds. After this procedure, the mode will change on the third setting of the selector."
