I like Diamondheads. Much like the Troy DOAs, let me dig up a review I wrote a while back.
My buis of choice have been Troys in the front, and their DOA in the back. I prefer the precision allowed by the diamond shaped peep, as it’s easier for me to reference if I have the front sight post dead center on the peep. I really like the long range setting which is a completely different setup. No peep sight rear aperture, instead they have two posts in the rear, curved inward. Like the ends of a caliper. All you have to do is center the front sight post in between the rear posts and put the front sight on target. I love that you get a very big sight picture with them. I don't like that if you are using the long distance setting, you must change it back to the peep setting before stowing the sight, otherwise the top of the diamond of the close setting rear aperture will come down on your upper receiver, scratching it, or gouging it, or maybe even bending the rear aperture if closed forcefully.
When checking the Diamondhead premium Diamond sights on the RUC, the first thing I checked was if it could be stowed safely on both the close and long range settings. I'm very happy to report that, yes they can. My initial impressions of the sights are pretty limited given the confines of the small showroom, but the close range setting is pretty similar to the DOAs. It actually seems to be a bit faster due to the shape of the flanges on either side of the front sight post, but I think I will be able to follow up in more detail at the range next weekend. They are nice and solid, and the unlocking button gives a nice positive click when depressed.
