Even if you have a high-quality optic or scope on your rifle, it is important to have a set of back up iron sights (BUIS) mounted to your receiver and rail just in case your optic fails. The Diamondhead Hole Shot integrated sighting system is designed to attach to your picatinny rail on either your AR-15, AR-10, or another similar weapon system. These revolutionary flip-up sights are low-profile so they will not be in the way when folded and not in use. They have no button to unlock and are simply held in position by friction so they can be deployed extremely fast for CQC situations. The rear aperture is designed for quick target acquisition at close ranges and is easy to sight in by using the proprietary windage adjustment screw. This pair of iron sights are a great option when using in conjunction with red dot sights and other optics.

  • Low-profile flip up sights
  • Quick deployment without button locks
  • Features Diamondhead patented diamond shaped apertures
  • Durable picatinny mount
  • Windage and elevation adjustable
  • Small and large aperture
  • Front and rear sight included

For twice the price of other REPUTABLE companies sights, youd think they could machine the front sight correctly. Awesome sight picture but I wouldn't put these on an airsoft much less "military" rifles.

Installed these sights on a Diamondhead VRS handguard in 2 minutes, Great sights, perfect for CQB application, zeroed in 3 shots, Best sights on the market! Fast shipping by Primary Arms again! Great Company to deal with! Will be ordering more from PA

Might be better than the original

I really liked the Diamondhead design- easy to acquire and line up- but I think the rear loop may even be better! These sights have detents to open and close; there is no button lock, but they engage firmly in the upright position. These are quality sights and Iā€™m very pleased with them thus far!

Excellent sights.

These are great, the sight picture is awesome and the fit and finish are very good. They seem a bit lower profile than the standard aluminum ones too. These are probably my favorite BUIS right now, and I've tried more than a few.
<br>Not sure what the two very vague 1 star reviews are talking about, but my set is very nice quality.

Good; not Great!

Quality is there and is what to be expected with Diamondhead. These are good sights, but not great. For a good sale price, I would recommend them, but otherwise they are just extensively overpriced sights! Very easy to go up and down; probably go back down too easily (I think so). In my opinion, There are much better options on the market for your money. I got a great deal on these and will continue to use them because they do their job well, but I wish the front sight adjusted more easily and I wish they required more pressure to fold back down. I personally don't think I will purchase any more sights that require the tool to adjust the front.
