King Arms upper receiver compatibility
 

Someone stepped on my TM M4 and that broke the receiver. I'd rather get just an upper receiver instead of a 240$ complete new receiver, as I already have a well working KA M4 (and not that much spare money, screw you gear addiction).

Considering that KA uppers alone are hard to find, I was wondering if there was any other make (that's easier to find, such as G&G) which would fit a KA lower with little to no mods?

Thanks!

Isn't the KA upper/lower the same as the G&P system?

I would think so.

so i just tried swapping the upper and lower on my king arms and my g&p, the king arms upper will not mate with a g&p lower but the the g&p upper will go on a king arms lower, but will be loose and the holes for the pin won't line up perfectly, off by about .5mm, so with shaving a little bit off a g&p upper might work.
