Top 5 Best Red Dot Sights for TRR8 in 2025
1. Trijicon RMR Type 2 Adjustable LED
Description: The Trijicon RMR Type 2 is the gold standard when it comes to red dot optics. With a rugged design, crisp dot, and reliable performance under stress, it’s one of the most dependable sights I’ve tested.
Specifications:
- Dot size: 3.25 MOA
- Battery: CR2032, up to 4 years of battery life
- Housing: Forged aluminum
- Weight: 1.2 oz
Best Features:

- Shock-resistant construction
Pros:
- Ultra-durable build

- Excellent battery life
Cons:
- Pricey
- Requires adapter plate for TRR8 mounting
Personal Experience: The first time I mounted the RMR Type 2 on my TRR8, I knew I was handling a professional-grade optic. Despite needing an adapter plate (I used a dovetail mount from EGW), installation was simple. At the range, the dot was crystal clear even in full sunlight. The automatic brightness worked flawlessly as I moved between shaded areas and open sky. I’ve dropped this sight — unintentionally — and it held zero perfectly. It’s not cheap, but you absolutely get what you pay for.
Online Feedback: Most users rave about its reliability and ruggedness. Some note that the buttons can be a bit stiff, but that’s a minor trade-off for the performance you get.

The dot was clean, the reticle switch feature was genuinely useful, and the Shake Awake worked perfectly — waking up instantly when I picked up the gun. One time I left it in a bag for a week and the battery barely drained thanks to the solar panel. This is an excellent pick for those who want features without breaking the bank.
