Questions & Answers
Can I use this on a 16in 762x39 using 123 grain Tula usually, for supersonic holds Expert Answer

The Trijicon 4x32 BAC ACOG Rifle Scope could be used for that rifle and ammo, however, the BDC reticle holdovers will not be as accurate since they are designed for 300BLK. These models will be closer than the 5.56 or .308 reticles though.

Will this work with a 10 inch barrel on 300 blackout ? Expert Answer

Yes, the Trijicon 4x32 BAC ACOG Rifle Scope will work for your 10" 300 Blackout rifle. This reticle was specifically optimized for 300 Blackout with a 16" barrel. Since you have a 10" barrel, the holdovers will not translate perfectly.

Great ACOG to use by Ryan Tarczynski, Gear Expert, November 23, 2020
While I was in the service I used this Trijicon while in the active duty. These were great to use to help improving shooting, since you can see clear as day when your shooting a far range target. Even while shooting paper targets can easily tell if y...

Helpful Positive Review Great Scope But Decided to Return It by monaskon, October 23, 2015
This is a great scope. Target acquisition is fast, the left/right bullet drop horizonatal has marks are easy to understand, and 4X is fine for what is essentially a short to medium range cartrige. But, sadly, I decided to return it. The reason is tha...

Helpful Positive Review ACOG for 300 Blackout by RM, April 12, 2016
As with all ACOG scopes, excellent and easy to use - but the specific set up for 300 Blackout is excellent. Easily allows switching between super and sub sonic ammo without any changes to scope settings.

Product Info for Trijicon 4x32 BAC ACOG Rifle Scope

This 4x32 BAC ACOG scope provides a dual-illuminated reticle using fiber optics and tritium for a bright aiming point in any light condition. The 300 blackout reticle with merged aiming points has been optimized for simplicity and efficiency. It allows the user to instantly switch between supersonic and subsonic ammunition without having to re-zero the optic. The supersonic BDC (out to 600 yds.) has been merged with the subsonic BDC (out to 200 yds.) to provide one set of aiming points for both types of ammunition. The reticle drops are based on an average of commonly available off-the-shelf subsonic and supersonic ammunition from a 16" barrel. This BDC reticle is not limited to one or two specific bullets: a majority of commonly available ammunition will fall within the 2 MOA diamond aiming points. The 2 MOA diamonds offer a balance of speed and versatility based on the unique performance of the 300 Blackout caliber. The drops in MOA for each aiming point are provided for users who wish to develop their own handloads for use on firearms with a barrel of 16" or shorter, or for those who wish to deviate from the recommended zero distances.image
