This airsoft gun by Raven is based on a famous pistol which was originally developed in the 1980s at the request of the Austrian counter terrorism unit EKO Cobra. They needed a selective fire pistol which was capable of full-auto fire in case they were in dire situations which required a high level of fire in a short period of time. This replica airsoft gun by Raven is a whole lot of pistol for a very small price, but this in no way means that they have skimped on quality! The pistol is constructed from metal and durable polymer and features compensator slots in the slide and outer barrel to give this airsoft pistol a really unique look! The pistol has a large fire selector on the left side of the slide enabling you to select between semi-auto and full-auto fire modes. The gun comes with spare parts just in case you have any issues in the future and also comes with optional back straps for the pistol so you can adapt it to your hand better.
