Might get a red dot or a small 3x scope in the future though, I'm not sure yet. First priority is for the panic to die down so I get my hands on more mags and .223.

That must be some gun companies marketing because the M16A3 is a fully automatic M16A4 ordered in small numbers by the US Marines.What makes an A3 an A3 is that it has a sear that allows fully automatic fire over an A4s three round burst.In the military the upper of an A3 and A4 are exactly the same.
The A3 you are talking about has to be some firearms manufactures name for an upper receiver that has picatinny rails.I am curious though why have an upper that allows for the direct mounting of sights but not not some other site other than the carrying handle mounted one?Seems kind of a moot point.I would buy an optic and get the full benefit of the upper from the start myself and if I could not afford them all in one go I would buy a rear sight that mounts on the upper first that way I have a back up iron site available for immediate use should the optic fail once I was able to purchase one and a usable weapon with iron sites in the mean time.
