Sig Sauer Romeo3XL 1x35 Rifle Reflex Sight - Operators Manual

What mounting plates work with the Romeo3XL on pistol slides?
The Romeo3XL uses a C-More footprint but requires specific adapter plates for pistol compatibility.

Why does my windage adjustment spin freely without clicking?
Contact the SIG warranty service immediately, as this indicates a failure of the internal mechanism requiring professional repair.

How do I properly zero this rifle's red dot sight?
Start at 25 yards, adjust brightness to the lowest visible setting, and use elevation/windage turrets at 1 MOA per click.

What's the actual battery life with MOTAC technology enabled?
Expect 20,000-25,000 hours of mixed usage; MOTAC extends the device's life by automatically powering down when it is stationary.

Does the tactical red dot optics warranty start from the purchase date?
No, SIG's 5-year electronic warranty begins from the manufacturing date, not the purchase date. Please verify this before making a purchase.

Can I mount this on AR-15 rifles with standard Picatinny rails?
Yes, includes low-profile M1913 mount for direct rifle red dot sight installation on standard rails.
