Details
Description
SIG Sauer ROMEO4T-PRO Red Dot Sight is the CR2032 member of the ROMEO4 professional line: a 1x20 mm rifle dot with four selectable reticles — a 2 MOA dot, the same dot with ballistic holds, a 65 MOA circle-dot, and the circle-dot with holds — so one optic covers speed, precision and holdover. MOTAC stretches the CR2032 to in excess of 50,000 hours, and it is tested to MIL-STD-810G and submersible to 20 m.

Product FAQs
Should I get the ROMEO4T-PRO or the ROMEO4XT-PRO?

What do the four reticles on the ROMEO4T-PRO give me?
The SOR44101 offers a plain 2 MOA dot for precision, a 65 MOA circle-dot for speed, and either of those with ballistic holds beneath. One optic therefore covers speed, precision and holdover.
