Geonox Airsoft got to test the Vorsk Hi-Capa 5.1 Gas Blowback Pistol in this video review... "In this video we take a look at the Vorsk Hi-Capa 5.1. Vorsk has not only built something beautiful here that is nice to look at from the outside. The outer barrel, which is located under the sled, also looks very nice. As the name suggests, it is a Hi-Capa design. That means our long mag and our drum mag fit in here and feed too. The special thing about the Vorsk is that you have a thread at the front and a thread adapter with you. You don't have to worry about which red dot sight fits here and how to mount it. The Vorsk comes straight out of the box with a red dot sight. Many thanks to Sniper Airsoft Supply, who made the Airsoft available to me."
