As the title reads, what combo for front and rear open sights do you prefer? I don't mean what brand but shape(round, square, bead, aperture) and size. Also for what range in distance do you use this combo for and for what length gun(carbine, mid-length, or rifle)?

On my main home defense Colt LE6920 16" carbine gas I prefer just the factory standard square front sight post and I'm using a large aperture of my Knight's Armament 300m folding rear sight, I use this carbine point blank (furthest wall indoors) up to rarely 300 yards outdoors, mostly under 100 yds.

I have another Colt 16" carbine I use as backup with same factory front sight post fixed front sight but it have a large diamond shape rear aperture of my Troy DOA folding rear sight, I just prefer to use this sight combo for indoors and very short range low light conditions, outdoors on bright sunlight there's too much light going through the aperture that I have a hard time seeing the aperture.

My precision 16" midlength gas carbine 6721 also have a standard factory square front sight post on fixed sight base and I'm using a same plane round aperture (large aperture at 0 to 200 yds and small aperture up to 600 yds) Troy folding rear sight.

With my only 20" A2 rifle gas with USGI M16A2 Colt upper half its just the factory square front post sights and fixed A2 carry handle upper receiver, I use the large aperture 0 to 200 yds, the small aperture sight could be elevated up to 800 meters but I don't shoot that far, I sometimes shoot it at only 600 yds.

When I was shooting competition rifles in the late 80s I'm using smaller than factory round match front sight post and smaller target aperture with finer elevation adjustment rear sight on my Colt AR-15A2 Sporter HBAR 20" rifle.

I took off the rear sight the came with my SOCOM and replaced it with a KAC Micro 200-600 rear sight, and the aperture that comes on the KAC is perfect for my astigmatic eyes. I can actually shoot a tight group at 100 off hand with it.

XS Same Plane rear, XS white stripe front.

This, on several carbines; on a 5.56, a 9mm and a .22. Realistically, short of a revolution, you're not apt to need sights regulated to 300 yards. The 'same plane' sights give you options of greater speed or greater precision at practical shooting distances, and the white stripe front can be picked out of a broken background much more effectively.

I have the XS Sights 3/32" White Stripe with tritium insert front sight on both of my AR's. I use them with both NM A2 rear appertures. I keep my house gun set on the large apperture. For range time I shoot the house gun no farther than 50 yards and My LE6920 out to 200 yards and then use my EOTech XPS2.

There's a lot to be said for the reliability and simplicity of irons, and never a question about batteries. Maybe it's a comfort thing as well for those of us who trained on them in the dim mists of time in the 20th Century....

I like the standard rear aperture size, and I turn down the front sight post in a drill with a file to around .040. I use this set up on a 20" barrel rifle and have used this set up out to 600 yards effectivly. I use a 300 yard zero, and I move the front sight tower out to the very end of the barrel behind the comp to get the most sight radius possible. It looks like this.
