Well, I can see that this is intended to be a photo of the Magazines... recycling photos is one thing... but one of a Crossfire?!?! :barf:
I like the idea of a combo gun too. However the Crossfire solution looses the abilities of both gun concepts... You cant use it like a regular shotgun, and you cant use it as a regular .223. It is totally pointless. Its a Tactical Vomit that is less than the sum of its parts.
Now, you want a GOOD Crossfire idea?
Take that shotgun and put it on the bottom... this way you can do tactical reloads with a regular feed tube as God intended shotgunners to do. With out this your better off WITHOUT a shotgun.
Now, for the .223. or 9MM or whatever the heck you want... Put that on TOP of the shotgun. Take an AR type receiver and make it eject out the top. Then make a charging handle that works off the left side. Turn that sideways - 90* to the right and mate that to the shotgun's receiver. Presto! You have just made the CROSSFIRE 100% BETTER.
Further impovements?
You dont ask much do you?
Fine...
Instead of an AR layout for the .223, use an AK action modified as I described for the AR and leave it chambered for 7.62X39!
Wait - Better? Dang!
Okay fine... FAL then!
