Guy's I have an Olyarms' K3B and would like to use a CMMG upper to make it a flattop.
My ? is if the Olyarms' part's would go together well with the CMMG upper?
I don't wanna drop $$$$ on an upper and not have it work properly.
I'm a year in on the AR, so still learning about them.
gotta admit since getting this one I have taking a liking to the lil "bugger"!
