This is a concept rifle I put together for something to do. It's a single shot configuration, and each round is roughly the size of a can of pop (a pointy can of pop.) The gun would probably take off your shoulder with the recoil it would put out, but there's plenty of room under the barrel for a recoil countermeasure.
Everything in the gun is made by me (including the scope, and the graphics.) Any questions please feel free to drop me a line on my internet mail box majig. Post code; theexpertdude@gmail.com
