- Battery life and replacements: Consider included battery counts and how easy it is to source replacements in the field.
- Reticle and sight type: For red dot sights, evaluate reticle options (4 MOA vs 2 MOA) and brightness levels; for bore sights, evaluate alignment accuracy and durability.
- Durability and construction: Brass or metal housings tend to offer better longevity in harsh range or field environments.
- Ease of use: Quick-insert bore sights and simple adjustment procedures save time during setup.
- Portability: Compact bore sight kits with protective cases are ideal for travel and field use.
When selecting a red dot or bore sight for .308 rifles, prioritize compatibility with your weapon’s chamber and rail system, expected shooting conditions, and how frequently you anticipate needing precise alignment before live-fire sessions.
