Monty, guest, from VA, United States, asked on February 27, 2018

Is this the same model issued in the Army? Looking to build an M4 clone but there are many different kinds of ACOGs out there.

A
Answered by Ski11B, member, from CA, United States, on March 02, 2018

Yes it is. It's the standard issue ACOG for the US Army. I used this exact model on my deployment to Afghanistan. Anything other than the description on the Trijicon website is the incorrect model: "TA31RCO-M150CP: Trijicon ACOG 4x32 BAC Rifle Combat Optic (RCO) Scope with Red Chevron Reticle for the US Army's M150 with Thumbscrew Mount"

Q
Sean, guest, from PA, United States, asked on March 28, 2021

Ive read this is for a 14.5"/16" AND 20" barrel by splitting the ballistics. Is that true? Or is it meant for M4? Are specs same as USMC TA31RCO-M4CP?

Expert Answer
A
Answered by Tom B, Gear Expert, from IL, United States, on August 30, 2021

The manufacturer's website give very specific details about all 47 models of the 4x32 ACOG. The M150 model you are referencing is indeed designed to be used with the M4. They both incorporate the USMC reticle. The only difference I can spot between the two models you are asking about is the inclusion of flip caps on the Army model. Trijicon also has a very useful compare model function on their site.

HOW MUCH TRITIUM IN EACH ACOG?

A
Answered by drew, guest, from TX, United States, on May 22, 2021

It lasts 10yrs relatively, once the tritium is dead send it back to trijicon and they will repair it at little to no cost
