The ACOG/RDS combo is a favorite for our 5.56 rifles. It works well for short- to medium-range engagements, offering plenty of speed up close and magnification for longer shots without needing to operate a throw lever like you would on a traditional LPVO. This TA31/Trijicon RCR combo comes assembled and ready to go out of the box, offering a durable and convenient optic setup that just needs mounting and zeroing.
If NV capability is important to you, we recommend the LED model (TA02) that offers a front-mount location. This combo is still a great option for an ACOG/RDS combo outside of the Night Vision use case.
WHAT’S INCLUDED
- Trijicon ACOG 4×32 (TA31)
- Trijicon RCR 3.25 MOA
- Thumbscrew Flattop Adapter (TA51)
- LensPen (TA56)
SPECS
ACOG FEATURES
- High-quality glass and multi-coated lenses maximize light-gathering capabilities and a clear field of view with zero distortion
- Able to withstand recoil from a .22LR to a .50BMG and everything in between
- Performs in extreme cold and heat with dry-nitrogen-filled housing that mitigates fogging
- Easily passes U.S. Military drop test requirements
- Minimal moving parts, creating a nearly indestructible sighting system
- Exceptional waterproof performance that exceeds military standards
- Forged from rugged 7075-T6 aircraft aluminum
RCR FEATURES
- The unique mounting system allows the optic to mount using the existing RMR bolt pattern.
- Same deck height as an RMR.
- 7075-T6 forged aluminum housing.
- Powered by a top-loaded CR2032 battery.
- Offers the same housing shape as the RMR now in a closed emitter version. It still diverts the force of an impact away from the lens, greatly increasing drop survivability and one-handed slide manipulation.
- Ruggedized battery contacts and electronics ensure performance and survivability.
- Wide-band light transmission ensures minimal change in target area color.
Made in the USA.
