Pair it up with our Magpul MBUS Front Flip Up Sight (ARR-851).

Made in the USA.

Reviewer: Dan
The day aperture seems small. Sure, the smaller they are, the more accurate you can be, but I had a hard time focusing due to the small size. The large size of the front post didn't help. I think if I replaced the front sight post, I might like it better. I have a KNS Precision Item # 2-KNSSIGHTPAK front sight on my AR and love it. Not sure if those would replace the front sight post or not. These sights I actually bought for a friend's B-Day. He likes them as back ups, which is what he uses them as, but wouldn't use them as primary. They aren't accurate beyond 100 yards. The front sight is too big and the back is too small. They were the standard carbine distance apart from each other. I'd buy again if I knew I could change out the front sight post. But I'd be more likely to buy a higher quality folding sight that costs more.

As for those complaining about the aperture being small, the smaller it is, the more precise it is. All in all, great and sturdy sight.

Reviewer: Alan
When I first got my hands on this sight, I thought it was a cheap piece of plastic, but to my surprise it is a stout peep. They should add in the directions that you can fold down the small hole sight for the large sight. I will buy again.

Got exactly what was advertised. Works great on my DPMS and was $60 cheaper than what my local gun shop wanted.
