Customer Ratings & Reviews
good and sturdy AR-15 sights
Good pair of AR-15 sights, my only complaint is the front sights release button is a bit sticky so when you put the sight down, it doesn't stay down sometimes
Polymer Back-Up Sights
These Flip-up AR-15 sights compare very favorably to the Magpul MBUS, but at a lower price point. The mounting screws are made of a weaker material; be careful when tightening them. The front sight post has a spring-loaded detent, unlike the MBUS' manually-inserted roll pin. The precision ghost ring flips down (leaving the general-purpose ring in its place) when the rear sight is raised, which I consider a feature rather than a flaw.
Great Flup up AR-15 sights and service
I checked everywhere and got my best deal on the arms 71l here. I received my ARMS AR-15 sight set and found the front sight would not rise to its full extension. Appeared to be an issue with the spring. I contacted the sender, and they sent me a new one with a return envelope in a couple of days... no hassle, no questions other than what's wrong with it. They fit my flattop perfectly and align immediately when the rifle is shouldered. The rear sight adjusts with positive clicks and has two different apertures. The only reason I didn't give a five is I believe if it's adjustable, the adjustment tool should come with it (the front sight in this case).
flip up buis
This AR-15 sight system was straightforward to install and an excellent product for the price compared to MagPul. The adjustments were easy to make on my flat rail AR. They are my back up sight to my Aimpoint Pro red dot. I keep the front sight up to use in conjunction with my red dot. That way, I'm set for a close-quarters encounter on a long distance one.
