Let me make it clear; The M16A4 (Mainly issued to USMC) is mostly equipped with Trijicon TA31RCO ACOG optical sights. In close courter operations you can find M16A4’s with EOTech reflex sights (Many soldiers purchase with their own money) or the main carrying handle. One of the reasons why the M16A4 is mostly equipped with ACOG sights is, because the A4 is a longer range weapon and has a 20-inch barrel, meaning it’s more of a sharp shorter weapon compared to the M4 Carbine which is for close courter combat. Don’t get me wrong, this doesn’t mean the USMC doesn’t engage in close courter operations, what I mean is that the M16A4 is a more precise weapon compared the M4. Also on a side note, the ACOGs possess greater magnification compared to red dot/laser sights such as the M86 and EOTech which are more of a aimpoint. The M4 Carbine (Now being issued to the US Army, also used by the USMC) is mostly equipped with Aimpoint CompM2/M68 CCO or EOTech style sights. In particular occasions the M4 would also be seen with the ACOG type (TA01NSN which has Bullet Drop Compensator) optical sights; it all depends on the mission. You’ll also notice that most M4 Carbines equipped with the Aimpoint CompM2 have a backup flip-up sight in case the optical runs out of battery or gets damaged. But rifles fitted with the ACOG type sights usually don’t have any backup sights installed, this is because the ACOG series do not use batteries.
So in short:
USMC
ACOG> CompM2
US Army
ACOG< CompM2

The U.S. Marine Corps is actually planning on equipping
every rifle with optical sights in the near future.
