How to Choose the Right Red Dot Sight for the Ruger SFAR 308
Here are some key considerations to make the best choice:
- Durability: The SFAR's recoil demands a tough optic. Prioritize sights with military-grade builds or shockproof ratings.
- Reticle Type: Choose a reticle suited for your shooting style. Dot-only for precision, or ring-dot for fast acquisition.
- Battery Life: If you want a "set and forget" optic, go for models with at least 30,000+ hours of runtime.
- Mounting Compatibility: Most red dots here fit directly to Picatinny rails. Always verify mount height for co-witnessing with backup irons.
- Weight: A heavier sight can affect balance. Go lighter if you're planning long hunting trips.
