  • Great red dot
Color: Flat Dark Earth
I've had this red dot for a little while now, and it has held up great! The window is big, so it makes it easy to find the dot, and the design of this is very nice - it's a perfect match on my P320 AXG Scorpion (it mounts directly on it without an adapter plate too). My only small complaint would be the rigidness, the aluminium of the red dot house itself seems a bit weak or soft, so it easily get marks on it, but I didn't put the steel shroud on it, but will probably spray paint it FDE to match the red dot/pistol and put in on in the near future. But overall, a great red dot. Definitely get this one over Holosun! ... show more

  • Great SIG quality and functionality, as always
Color: Flat Dark Earth
Great optics from SIG that complement the M17 very well. Large window, bright dot perfectly visible in broad daylight, battery access from the top, i.e. no need to remove the RDS to change the battery, properly sized mounting hardware and adequate torque values clearly stated in the manual and to top it off an optional steel shroud comes in the package (installing it is a must IMHO). As all SIG Optics, this has an infinite life warranty, with the S/N apparent on the RDS body, i.e. once again no need to take everything apart to get any info. Only very minor annoyance is the elevation and windage dials have very small notches. Yes, the RDS comes with a SIG tool to adjust the dials, but it's not a very practical tool and would rather use a screwdriver (which will require a very small screw driver). ... show more

  • These are wonderful and underrated
Color: Black
This top quality. I’ve got about every brand redeye you can think of. These are as good as all the top brands. Holoson, Leopold and sig are the three best. You will not be disappointed. Be careful of your footprint, and make sure that it fits your gun. I run this on my P320 and 8P226. Both work flawlessly. ... show more

  • Good Product but Battery Life Is Short
Color: Flat Dark Earth
I really liked this red dot. It took some doing, but it installed perfectly on my Sig M17. The accuracy was great once it was dialed in, and it was fun to shoot with. The problem was the battery life. I went through 2 batteries fairly quickly and soon realized that I couldn't aim accurately when this was installed and the red dot was not working. In an emergency, if the battery was dead, my accuracy would be limited. So unfortunately I have removed it. It does what it says it would and does it well, so I did not return it. I just can't rely on it for emergencies like I had hoped. ... show more

  • Couldn't ask for anthing else in a sight.
Color: Flat Dark Earth
This red dot is everything you could want and need. The zeroing process was effortless and simple, put about 500 rounds through my M18 with this sight attached and it holds the zero without having to make any adjustments. The motion sensor is also on point and activates as soon as I pick it up, although I'll have to see how the battery holds up after a couple of months of use but so far so good. My only complaint is the shroud that comes with it doesn't make pressing the brightness adjuster easy and is pretty much just a waste of time installing if you want operating this sight an easy experience. I also got the desert color, and the shroud doesn't color match it in that color for the shroud comes in black. All in all, this sight is as advertised and would recommend this to anyone that is in the market for a great optic. ... show more

  • perfect for my m17
Color: Flat Dark Earth
easy to install, bright as hell on the brightest setting. Love the look of it fit and finish is as expected with matching brands. i will say the FDE is not an exact match to my m17 but its within a couple shades of each other and looks great sitting on it.
