This sight is brand new, and there really isn’t much input about it. It looks promising though and I just wanted to get this up on FJ so guys know that it exists.
I do like the fact that this rear sight has a notch, just like a pistol. I also like the horizontal serrations carved into it, and this falls in line with the sight that Larry Vickers likes called the Slantpro Straight 8 by Heinie. I have that sight on my Glock, and it is an outstanding rear sight aperture for pistols.
But like I said, I do not own this rear sight and I haven’t heard any feedback about this sight, except for one comment at the XS store website where you can buy this sight. On the CSAT website, they give a better description of how to use this new rear sight, so be sure to check that out as well.
Also, I wanted to give a heads up that CSAT is coming out with a new rifle based on the AR 15 platform and that this rear sight will probably be a standard feature of this rifle. It will be great to see the final product in the near future. –Head Jundi
