Planning to get front and rear Troy BUIS. Which style of front sight do you recommend - the M4 or HK styles?

M4 style

HK style

This is for my first AR build, and the rifle will be used for fun, light competition, and home/property defense if the need arises (unlikely, but not impossible give I live two miles from a major faultline in the Bay Area).

Thanks!

I find that the ring of the HK style sight "locks" the eye into the center of rear aperture much better and speeds pickup.  I've engaged man-sized silhouettes at 400yds using these sights and was easily able to score consistent hits using holdovers.  The AR type front was made to please the more traditional AR crowd.

I'm in Foster City.  Where U?

I just ordered the new diamond rear sight and the HK style front.  Why?  Just like the looks of the HK front better....it really is a personal preference.

The problem with the HK type protective ears is the same thing that makes it great for some ... with the semi-circle protective ear, your eye will natuarally align the rear apperture (circle) with the semi-circle protective ear of the front sight. It makes for a very fast sight aquisition ... when you engage targets at the correct distance for that setting.

You will start to have problems when you zero your rifle using the elevation adjustment of the front sight. When this happens, you will now find that your eye still tend to align the front semi-circle protective ears with the rear apperture and not the front sight post. It can be a PITA and confusing. This will however not be a problem if your rear BUIS also has an elevation adjustment and you use that instead of the front.

I have one of each. I prefer the HK style.

True enough, and I considered that when I got my first HK style sight, which was a PRI flip up gas block.  I've owned and built quite a few ARs, and never really had one that required a gross adjustment to the front post up or down.  The only one I did was my M16A1 in the Army, and someone probably used it as a pry bar at some point.
