Here's a closer look at the Bel Tec Airsoft Sentry Gun that was on display at the RedWolf Airsoft booth during the IWA & Outdoor Classics 2014. Taken by Airsoft Keks, there were two of these on display. Useful for fixed defence in airsoft games and should be a tough one to get through even at night as it has IR vision and you can control it remotely.
