Why choose when you can just take five guns?
We have all been there. You're not sure what gun to use or carry. It might be for a hunt or a trip to the range.
The video below has a solution to your problem.
If you are curious the five guns are: Derya MK-10, an 870 Wingmaster, Marlin 1895, UTS-15, and finally an IWI TAR-21. I'm not sure how you really aim this contraption but I don't really think you need to. I'm trying to figure out how all the guns are attached to one another I'm hoping they are connected somehow by brackets and in the pictures it does appear that way. Or duct tape, that's not safe but it works.
I can't blame him for changing his stance. 50 pounds loaded and he sounded like it started to hurt after a while. I would probably want to find a different way to support that weight as well. I can't imagine it has much recoil so at least that's nice.
