I tried doing some searches (google, youtube, calguns, ar15) and didn't find what I was looking for. I hope I am posting this in the right place! I am fairly new to using and building AR platforms. I saw these:


I have a mega arms billet lower with timney drop in trigger, etc (lower is complete). This reminded me the Skar rifle, but if I purchased this upper and BCH with SIDE charging handle... will it still work with .223 lower I have and will I still need a rear CH???
Also, are there any pro/cons to a side charging handle vs the rear CH? ANY HELP IS MUCH APPRECIATED!
