    Glad it's made of steel

    I have my backup rears installed in front of my pistol optic, mostly because I like to beat against it if there's a jam, or I need to rack the slide one handed. Glad I found something made of steel, serrated, and suppressor height.

    GLOCK OPTIC HEIGHT REAR SIGHT

    Previously I used another major brand three dot optic height night sights for my Glock 19 Gen 5 MOS. I decided to switch on over to 10-8 for a couple reasons. First, I prefer the U notch versus the square notch on my other sights. Second, I also prefer not having the distraction of the tritium dots on the rear. The quality of these appear great, but I will just throw out there that they did require some fitting/filing. I want to pretend that I am some hardened gun-fitting expert, but sadly, that is not the case. I am a bit more used to just smashing things in with a hammer and calling it a day. I did have to use a file to get it to fit and I think the efforts were well rewarded. I feel like it is fit to my weapon, and also enjoy the top screw that holds it down which I have not seen on most other Glock sights. Plus, let's not discount that I walked away from the experience having learned something new, how to fit a part to your gun versus the smash it in with a hammer until it complies thing I mentioned earlier. One last note: I installed these on a Glock 19 Gen 5 MOS using a Trijicon RMR on a CHPWS plate. These definitely sit much lower than my previous sights offering more of a "lower 1/3" cowitness versus dead in the middle. I find this to be another positive but wanted to leave that note for everyone's awareness. Overall, very happy with this product and recommend it highly.

    Pretty much perfect…

    Not sure what else one could want in a RMR backup rear sight. Appears to be made well. The only thing I can even come up with as a not perfect is the amount of material on the “ tail” sight doesn’t fill the dove tail. Does come with a set screw but would like to see just a bit more material. Great lower 1/4-1/3rd cowitness on a MOS w/ RMR. Exactly what I was looking for at a good price point.

    Fit my Glock 43x

    I was worried it wouldn't fit my milled 43x slide. 100% co witness with my Holosun 507k and direct milled slide.

    Glock MOS sight

    Excellent quality sights. I always check here first to see if they make sights for my pistol before buying elsewhere. I’ve installed several 1911 sights, Glock sights and M&P sights from 10-8 performance. Always excellent quality you know what your getting and seem to require the same fitting which is welcome. No surprises when fitting the sights. Thanks for making an excellent product.

    Glock MOS rear sight

    Installed smoothly and works great with tall 10-8 front sight

    Rear sight

    Sight is very high quality. Fitment was very tight. I paired it with the black front and am very happy with them. They just stick up just enough to co witness with an RMR, no more than necessary. Will definitely purchase more 10-8 sights in the future.

    Glock Suppressor/Optic/MOS Rear Sight

    I have this sight installed on my Glock 40 (10mm Auto) with a RMR and they work great. Perfectly co-witness with the RMR and the sight picture is excellent.
