Love the sight

excellent sights, for the price
back up rear sights are very pricey. however, if you're in a pinch like I am, these Magpul sights are pretty good. They sit pretty snug on my Colt upper. I haven't tried it out myself, but I've been told that these sights retain zero after being dropped on. Take it for what it's worth, but for a price point like this, you really have nothing to lose with these Magpul rear sights.

Back up sights
Quality piece of essential equipment. Great shopping and prompt order shipping.

Awesome sights
These worked really well, easy to install & easy to zero. Good as back up sights if my EoTech goes out.
-
good enough
A little bulkier than Troy's or similar iron sights but also half the price. Switching between the two apertures is also a little more difficult than iron sights because they snap together. Gets the job done.

Great as primary or secondary irons on a budget
So you have a shiny new rifle. Now you need sights. That EOTech is great until the batteries die. Backup sights are a must. These are great. Plastic. Made in the USA. And spring operated. When I put them on my rifle and shot it for the first time I didn't even need to adjust elevation or windage. Your mileage may vary. It's important to note that the rear piece can be adjusted for a larger sight picture. This comes in handy with CQB, low light and general crappy eye sight. SKD shipped fast and cheap. Thank you Magpul and thank you SKD.

Great sights
I have Magpul BUIS on all of my ARs. I have used other BUIS's by troy, midwest and dpms and these hold the same standard of those while being both lighter and MUCH CHEAPER!

very solid
Was better than i thought it was going to be, fits great. Peep hole is very clear and works well with both eyes open. Co-witnesses perfectly with my dot site. To sum it up, worth the money! Perfect buis!
