I have the Troy front/rear iron sights on my midlength AR. I feel the front post doesn't lend itself as well to precision shooting from 0 to 100 yards as the front post on the Troy is pretty thick and wide. What are your thoughts on the KNS front sight posts and which would you recommend? They offer crosshair version and also square and round post versions. I also like the V-notch & inverted V version.

Hmm. Perhaps changing the diameter of the rear sight peephole in combination with a thinner front sight post can help.

Unless the KNS front sight upper portion can rotate separate from the stud (which I doubt) you do lose some elevation adjustment on your front sight. Normal posts can be adjusted 4 clicks per rotation, but with these you can run only two settings (front & back) and miss two elevation settings.

I bought one for my DSA FAL. I modified an Israeli rear sight to use a fairly fine Lyman peep rear - basically tapped & threaded the existing peep to take the Lyman - and thought the KNS would provide a finer picture. I have a Rem 40X and Winchester 75 with all the goofy Parker Hale & Redfield peep stuff you can attach, my eyes hover around 20/15 so I thought this would be a nice set up.

It would be better if that upper vertical cross hair were not present. Turning it without marring the finish was a challenge and the darn thing canted to the right a bit, which just drove me nuts so I removed it.

I've seen a lot of reviews on this sight and most have been positive. I have read some problems though that some sights might have a problem with getting it to hit zero. Some people have stated they always shoot low or high no matter how much they try to move the elevation. My guess is some front sight posts (mostly a1's from what I have read) may have problems with this sight. Some other things that people have noticed is it's not steel, but is made of brass; though they have not really found this to be a major problem. Overall though, it has received pretty good reviews. I'm thinking of trying one of these myself, but for now I'm looking for other stuff.

I've got one on my shorty. I bought it because it intrigued me, but I quickly learned to like it a lot. It's really easy to align the crosshairs in the rear peep, as opposed to centering the post.

I bought the crosshair because I thought it would be neat and unique on my rifle. Truth betold, I hate using irons and prefer optics so I never really used it. But I wanted to highlight what BWiese said:

Bill is 100% right. You will lose some ability to adjust the front sight.

Soon I will be selling all my extra stuff. Things I bought that didn't work for whatever reason. The KNS sight was just one of them. It's useless at 500-600 yds. It blocks out the whole bulls eye.

I had the crosshair sight on my AR and loved it.....I used to shoot the ar at steel 400-500 yards all tghe time and had no problems
