Bought a airsoft gun from a Pawn shop a while back and have been using it for a bit. Works great and shoots like a dream, with a metal gearbox. but I have no idea what make it is. I had the thought that it might be a Dytac but haven't been able to lock anything down. Any input would be helpful. When I bought the gun it had a tan vertical grip and no sights. It says "Milsim Only" on the barrel, and a C AF on one side of the upper receiver. Also has a patent number on the stock, but i've come to learn that its just the style of stock, not gun.
Gun I thought it was: http://www.evike.com/products/42658/
The reason i'm not sure about this being my gun is that one says "Knight's Armament" and mine doesn't, mine says Milsim Only.
