Trijicon RCR Red Dot Sight FAQs
What is an enclosed Red Dot Sight, and why is it good?
An enclosed Red Dot Sight covers the laser inside a tough metal box. Because the Trijicon RCR covers the internal components, it can withstand the harshest environments. This design protects the glass from bad weather, making it a highly reliable Red Dot Sight for duty pistol use.
Do I need extra adapter plates to put this on my gun?
No, you do not. The Trijicon RCR mount compatibility is very simple. It uses the exact same RMR bolt pattern as older sights. You do not need to buy or use any additional plates to mount it. It fits directly onto standard cuts, making it an excellent enclosed red dot for Glock and other popular handguns.
What is the battery life of the Trijicon RCR?
The Trijicon RCR delivers up to 6 years of continuous operation on a single top-loading CR2032 battery when maintained at brightness setting 5. The top-loading battery deck allows operators to quickly swap power sources in the field without dismounting the optic or losing their established zero.
Can I still use my iron sights with this optic?
Yes, you can. The Trijicon RCR has the exact same deck height as the RMR. This allows for easy use with your regular RMR-compatible iron sights, so they will still line up perfectly when you look through the glass.
