AR-15 Type Rotary Barrel Upper Receiver?
 

http://images2.wikia.nocookie.net/__.../Gatmalite.jpg

I found this image on the web. It's called GatMalite, the KAC's unknown prototype version of AR-15 upper receiver that uses rotary barrel like from webley semi-automatic revolver, which enables the rifle keep fires without overheating but still maintain low rate of fire for rotary barrel(650 rpm).

I also found that once this image and explanation was on the wikipedia, but it's been deleted for some unknown reason

I am thinking this is not the real weapon, but i am just curious whether this one is really fake or not

Does anybody know about this receiver conversion kit?

Well that image looks pretty fake.

Yeah, it's completely fake.

Well lets debunk it using breakdown logic. It's fitted with H&K 416 sights, that are mounted too high up on the weapon to aim properly, and also the sights are oversized. The barrels are taken from a Dillion-Aero M134 Minigun, the bipod is clearly photoshopped on and is a different color, the gun would weigh a ridiculous amount that would be impractical for usage, and lastly, why would this weapon be in any way practical? It's fitted with a 20 round magazine, which when fired from a rotarary weapon would empty it in literally a second. A beta-C 100 mag would be cleared in 6 seconds tops. This is a weapon with absolutely no practicallity in combat. Hell, even mall-ninjas wouldn't have any use for it, it only has ONE side rail.
