It's about time - SIG SAUER Romeo4 Compact Red Dot Sight 1x20mm 2 MOA Reticle Low Profile With Torx Mounts Graphite Finish

I would say sig made up for releasing Sigtac back in the day by releasing these. Great site for the money and well built. Waterproof being a big plus (it did pass a test we put it through). Lens are top notch way better than expected. It's no aimpoint but will give the market the opportunity to come close to that quality with half the price. It is a really good option. I will even say better than the Trij mro. I was not impressed with the small magnification and red glare on the lens it had. It just threw me off. The Romeo 4 though you don't have to worry about that at all. Just get one and you will be happy with your purchase and feel safe if it is a go to weapon optic for you. By the way it holds zero after thousands of rounds even taking it off one rifle and putting on next!
