    What is a good BUIS for an 9mm AR pistol? I've been putting one together for PCC competition and have settled on a Holosun sight, but would also like BUIS for it.

    Unfortunately all of the BUIS that I've looked at seem to be designed for rifles. It seems to me that the site acquisition is not very quick because most of the sights are designed for 100 yard shooting and have small apertures 9mm AR condensed.jpg .

    Advice welcome. Thx.

    Ask Shawn @TSConver about that offset pistol sight he had on his 3-gun shotgun. Perfect for your application...


    Or something like this...

    All AR rear sights have a small and large aperture, to include the magpul MBUS.

    If that was my pistol i would roll with the MBUS front and rears. As to the zero, any zero under 75yds in a pcc caliber is fine, the fsp will have enough travel.

    One smooth option for you if you want non-popups are the HK clone sights.

    I really like the MBUS as well. Inexpensive and effective. PSA has them for around $50 on sale for both front and back quite often m.

    The A1 sight has dual small apertures on different planes, one for 200 and one for 300, no?

    A1 yes the centers are drilled differently. And the numbers equal the theory.

    All other A2 / flip ups have small and large apertures for uses that help to have larger apertures.

    And same size apertures. Both small. Was responding to this quote: "All AR rear sights have a small and large aperture, to include the magpul MBUS."

    That is incorrect. EDIT: Would also point out there are several sights that have only a single small aperture. Like, for example, the popular and well known KAC folding sights.

    Also, the centers are drilled differently on the A2 sights (and almost all other AR sights) as well. The Large aperture is intended for 200 yd zero, while the small aperture is intended for a 300 yard zero.

    To get same plane centers, you likely have to buy an aftermarket solution like the Blackhawk Same Plane Rear sight.

    John, that's an interesting option, since I am very familiar and comfortable with the HK sights. Thx. Scott

    Ok then enjoy your knowledge.

    Please just point out the incorrect information so we can all learn from your experience. I have all the sights sitting right here in front of me.

    Of all the dudes on the forum, I thought you could handle some straight talk.

    Check out the Diamond Head ISS. I like their setup.

    Interesting concept. I’ll have to sight through a set to see.

    I don’t want to get in the middle of this, but I always thought that the large vs small aperture was just about the available light. Learned something new today.
