awesome polymer BUIS. fit and finish is excellent. securely attached to my rifle. nitebrite is awesome and they were such a good deal. do not pass these up!
Great Price for a Great Product!
Building my first AR. Looking to maximize performance and value. These sights met my needs perfectly! Great fit on rail to serve as my backup sights. Got them on sale for about $60.00 for a full set (front and rear).

Great sight. Install was fast and secure, deploys quickly. sighting system works well at a various of ranges. As always PSA shipped quick.
Great for CQB - not so much for varmints?
by CHESTER LOTT
Has a roomy rear aperture and a specific shape to front site. Be very sure to look at the sight picture on the packaging because it is different from other sights. Place the front diamond in the rear. Simple. However the site post is big. So these are great for a 9mm carbine or any under 100 yard carbine/sbr. The sight picture is easily learnable and rapid to acquire with minimal training or even with "senior eyes". Solidly made.

Have never tried diamond sites before, makes for a good sight picture. I have these on a 10.5 9mm AR15 pistol build. As usual fast shipping and excellent service from PA, your emails are like crack!
Really nice concept and I like it
I have a set of magpul mbus and have been happy with those... I really like these diamondhead sights.. Acquisition is really easy with these compared to normal irons. Will get more when they come back up on sale for future builds.

Back up sights
by John Millirons
I like the sight, but only gave them 4 star for the following. The release buttons on both sights are very stiff you must put a lot of pressure to he them to release, and the controls are not lefty friendly. Other then those cons the sight are very nice. I love there glow in the dark options. Take just couple seconds to charge. PS awesome shipping from Primary Arms.
Good addition to my AR
by Bob Hewitt
I needed backup sights and found these on sale at Primary Arms.They are easy to install.Both sights are high enough that I can use them through an EOTech 512.
Primary Arms is the bees knees
by Daniel S.
I recently ordered a bunch of parts to finish off my first AR build. Primary Arms sent me all of my products within 3 or 4 days of ordering. I even asked for some stickers to "decorate" my gun case and they sent a variety to help lol. Definitely recommend to everyone I know. Awesome company.

I ordered these and the shipping was super fast. Very good quality item and very bright inserts. Great sights I like them better then the magpul ones. Primary arms is great!
Excellent Backup Sights!!
by Kin Bellew
I was going to order the more expensive version of these sights that were iron ones but went with the polymer ones instead that were half the price. Glad I did. Diamondhead sights are the best as far as I'm concerned. I love how they pop up at the push of a button and how you can just push them back down and they lock in place with a click. I also love how you can adjust the front sight. You don't need a special tool to rotate the sight post up or down. Instead they have a little rotating knob under the sight post to make your adjustment. I love these sights! I love the diamond shaped peep holes. It makes it easy to line up the front sight. Primary Arms is always a great place for me to shop and I keep them on my favorites list. Their service is great and shipping is fast.
Better than expected
by corey derryberry
I was weary to get these but was impressed at how nice they are. The illuminated sights are a bonus and take a "charge" quickly and last 30 minutes or so before needing recharged. Great sights for the money.
I love Primary Arms
by Lazaro Berrio
I've been a customer for a few months now, placed several orders and they were all shipped fast. Just recently I bought two PA scopes and I totally love their quality. I had to call in to ask a question about my order and was helped promptly and truthfully by a gentleman name Jim. I will definitely be a customer for life.
by Brandon Murphy
good value. Excellent front counter staff.
Nice price, got them on sale.
Everything is Awsome!!
by Andrew Caspar
OK first of all, always check this site. Sweet deals always pop up.As for the Diamondhead sights, these are well built solid flip BU(p)S. These blow Magpuls BUIS away. I should have bought more at the sale price, but I will wait till they do. Thank you PA you rock. Soon to spend $900 on optics and mounts soon :)
