Definitely recommended

High Quality 04/07/2017

These lay very low when they are not raised. They are very high quality and machined to very tight tolerances. So tight, the buttons to pop them up are pretty stiff at first. Mine needed to be lubed up and pressed a bunch of times. After that they started to loosen up quite a bit. That's my only complaint, that the buttons needed to be broken in a bit.

Slightly recommend

Rear sight isue 28/12/2015

The only thing I don't like about these sights it that the rear sight changes point of impact each time it flips up. There seems to be play in the assembly and trying to shoot 200 yard targets isn't working out well. It's a shame, it seems to be great except for that.

Definitely recommended

Nice sights 15/10/2010

I mounted these sights on an Adams Arms 5.45X39 upper. For the price, they are nice sites. They are not quite as refined as the Troy Ind., but nor are they as expensive.

Unlike the Magpul MBUS sights, they cannot be accidentally deployed. With a little lube and working the release mechanisms, they smooth out, but you will not have to worry about them popping open on you like Magpuls do if you touch them lightly.

These also lock in the UP position. All in all, nice sight that lay flat.

FYI, the rear sight has to be folded with the large aperture deployed - it won't fold down in the small aperture is at the ready. No big deal. I've always thought that if you have to deploy BUIS in hurry, you're going to want the large aperture anyway. If you have time to use the small aperture, you have time to flip it into place.
