Frequently asked questions

Can I switch between red and green reticles on the RT4S01?

Yes. The multi-reticle system lets you select red or green depending on ambient light. Green cuts through bright daylight better for some shooters, while red performs well in low light and indoor settings.

What does unlimited eye relief mean for this reflex sight?

Unlimited eye relief means you can position your head naturally behind the sight without losing the sight picture—no rigid eye-box constraint. This is valuable on rifles where recoil or shooting position varies.

What is an FFL transfer in California?

An FFL transfer is when a federally-licensed dealer like TacticCAL receives a firearm shipped from another seller and processes California's required DROS paperwork to legally transfer it to you. Find gun store Hayward at TacticCAL.
