I happened across my bro M4 Guru installing one of XS Sights new Paul Howe designed CQB apertures today. Luckily, I came in as he was finishing up, rather than starting the job, which meant I got to do all of the playing with none of the waiting. That makes for a good day.
What Howe came up with is a "pistol" sight notch above a more typical round hole aperture. Since the two are on the same...uh...blade, I guess...of the rear sight, transitioning between the two is crazy super fast, with just a slight movement. I tried to find a good pic of it, but couldn't. Figgers, M4G has brand new stuff before everybody else again. :)
This is the only pic I could find. I comes from the patent that Howe applied for, which is where the link in the title leads to. By all means, check it out, because it goes much more in depth than I intend to...or can, really. lol
Where the sight that XS makes differs from the illustration is that the "upper" notch is horizontally serrated, which cuts glare. The upper notch is for CQB distance shooting, while the more traditional peep aperture is for
shooting at distances out to about 25 meters.
According to M4G (who knows, believe me), Howe is very much anti-optic. The guys I've met who've seen him shoot or trained with him say that he's an amazing shooter and prefers open sights. After messing around with M4G's new sight for a short while, I'm very much intrigued, and I think I'm gonna have to seek one of these out and see if I can't slap it in my Troy Battlesight. This thing is slick! Well done, Paul Howe and XS Sights.
