Any one have or used the ProMag Sights

[jaymce]

Looking through Cheaper than Dirt and noticed the ProMag flip sights. Any one used or using them. I know that the better sight (troy, CG&G, MI, etc) will be better in the long run but the sights and a barrel wrench are holding me back @ this point. I do not want to buy junk and am not afraid to spend what will ammount to an extra 150$ on sights but as the rifle will be scoped with a good scope I am just wondering if the cheaper sights would do, or weather I am just going to be unhappy.
Things that would determine unhappyness would be not returning to zero, comming loose at base, and noisy cheap construction.
Thanks in advance to all responses.

Are you referring to the item:
Mfr# ARR162 http://www.cheaperthandirt.com/ARR162-57067-1887.html

The one you're looking at (from Cheaper Than Dirt) looks almost identical to the Flip-Up Rear Sight With locking detent (AR0169R) shown in the picture and link below ... only $55.03 cheaper!

I've read the reviews and they seem happy enough with it.

I have a Rock River AR-15 that came with the A.R.M.S. #40 flip sight:

I'm happy with it so far.
