stock Colt LE6920 M4 Rear sight?
What is the stock rear sight model that I need to order for this gun? I know it is made by magpul…
they call it a MBUS… But they have a metal one and a polymer one, I just want to get the right one that just comes stock with the rifle, which mine does not have…
also, where is the best place to get a carry handle?
thanks guys!

The polymer one is the one that comes stock on the rifles I believe(that is what came on mine), but by all acounts I have read the steel ones are better. I'd like to try one of the steel ones with elevation adjustment but am going to buy an optic first I think.
