Simple small slide mount red dot - SIG SAUER OPMOD ROMEO Zero Elite 1x24mm Reflex Red Dot Sight

I like the added steel OPMOD protective cover that does appear to add additional protection. I really, really like the circle dot reticle over the simple red dot. I think it's now time to consider certain polymers better than aluminum for these sights. Aluminum bends, polymers don't. The only "down" is that you must remove the sight to replace the battery.
