Optimized for the Sig Sauer M400 TREAD rifle but suited to the AR platform in general, the Sig Sauer Romeo5 1x20 Tread Red Dot Sight will get you on target quickly. It comes with low and 1.4" co-witness risers and features a 2-MOA red dot with eight illumination settings for daytime use and two low-light settings for night vision equipment.
The illumination circuit has a special Motion-Activated Illumination function (MOTAC) for powering up and down the reticle depending on the level of movement, which helps to extend the side-loading CR2032 battery's life to 40,000 hours in normal use.
The housing is IPX7-rated, watertight enough to withstand submersion to 3.3' with no damage.
