Thinking of buying a 204 upper from rock river. Can anyone tell me how well they shoot, cycle, ect. My understanding is that thy use regular 223 mags, will my 5 round 223 mags still hold 5 rounds of 204?

Thanks

Mike

A quick google search brought up this link on varminter.com they say the 204 diminsions are the same as the .223, as far as magazine fit is concerned.
And a quick look in my Hornady reloading handbook...
.223 diminsions 2.260" oal, .378" diameter
.204 2.245" oal, .378" diameter
