The issue was I hadn't installed mine yet, so I installed it this morning - the issue is not due to a lack of downloads. There is an error in the Spring assisted in the typical sense is not the case here. In spite of this, it does appear well made, and I will keep mine, since I can easily flip it up myself, instead of having to fiddle with In order to deploy, the spring assists, and after it is deployed, the spring holds it in place.

There is no evidence that they do not work. In my case, I only use iron sights for backup and they are zeroed close to zero. The durability of these has not been tested enough for me to know whether they are truly durable. They work great! Update they have been updated. Make sure you do a good job.

As of yet, it seems to be great for the money. Mounted it on an AR9 and sent 300+ rounds down range without issue.

I received it very quickly and it fits perfectly. It has a slight play while up, but it holds 1 inch at 100 yards. I had a very positive experience with the product overall, and would definitely purchase.

I would purchase these again because they were great value for the money.

With the AR15 red dot integrated into the flip-up sight, it gives the perfect visual perspective.

Product of high quality.


It should be noted that these sights were very well made and functioned flawlessly. The sights were impressive considering how much I paid for them.
I really wanted to enjoy them. There was an issue with the rear sight locking down when the rear sight was disengaged for down. It would be ideal if the default peep aperture was the large opening instead of the small opening, as this would correct the inherent problem with these sights. The problem is that the sight will not lock and pop up correctly on the 15 upper picatinny rail. The sights would make a great gift if the defect is ever fixed. I regret to say that at the present time, I would not purchase them in their present design. Sorry to hear that! A very well made product (with an unfortunate.
