I know everyone says that peep sights are the way to go - but I can't hit the broad side of a barn with them. 30+ years of shooting tangent sights, and I can shoot accurately out to 400 meters. Peep sights? I might be able to hit a clay 50% of the time at 25yards. On a good day. If I'm lucky.

And don't give me any advice on how to shoot peep sights - I can assure you I've heard/tried every technique out there over the years. My eyes just don't work that way.

I'm tempted to take a dremel to the top half of my rear sight, but would prefer something a bit more purpose built. Google has me going in circles.
 
Couple options . One is the notched A2 rear leaf . You can always machine the knotch to V

You can always take the Diamond head rear buis and machine off the top half to make your tangent V notch you want

Your front sight should have enough adjustment since you will be using the bottom of the V , vs the Diamond as a ghost ring

They are well build. I was given one . I promptly gave it away cause the weird shape just didn't work for me

Thanks.

Any chance you know if I can swap in that notch sight (option #1) for the factory apertures that come with Magpul MBUIS?
 
Keep in mind that if you are looking for a tangent style rear sight, it will really work best if it is positioned much closer to the front sight than a standard peep rear sight. Depending on how your AR is set up this may leave you with a sight radius as short as 6-8 inches. Not ideal.

......and simply because i can't resist, if you can cut off the top half of a peep and it works for you then you should spend a little more time with the peeps cause you are almost there. You are, in essence, using it like a peep already.

Disagree with that. I shoot a lot of tangent sight rifles, old vintage WWII era stuff. The longer the sight radius, the better.

Peeps just don't work with my eyes, never have. I know all the "tricks" (focus on the post, not the hole, etc etc), and put a fair bit of time trying to be able to shoot them well, and just can't. Something isn't registering with my eyes.

An old K98K sight, which is despised by many for being a difficult sight to master, I can shoot with ease. Different strokes for different folks.

What 8 Ball is saying is that in order for the notch in the rear sight to be focusable by your eyes it'll have to be significantly further forward than the traditional rear sight or else the notch will not be visible. Given that an AR's front sight (especially one with a carbine-length gas system) is not that far forward it will unavoidably give a short sight radius. Not that it hasn't been done on other rifles, like a short-barrel vz58:

What about something like the "See All" sight that Questar's selling...it seems halfway between an iron sight and an optic.

Ok, I see what you mean now... Yes, you would end up with a shorter sight radius, now that I think about it, and how you would have to make it work.

As for optics, I already have a 1-6x variable on order (and already have a good quality QD scope mount for it)... The thing about the BUIS is that they'll be just that, back up iron sights, not the primary sights.

Still, I'd like to be able to shoot well with them.

Thanks for the suggestions all, I'll figure something out.
 
I have a horrible hate for peep too, my eyes can't seem.to focus on them. I was browsing on an air soft site to order a steel underfolder AK stock and saw they had aluminum rear tangent sites for a pic rail. Not sure of the quality but for 30$ they might be worth a try.

Don't forget the high front sight height on an AR requires an equally high rear sight. It's likely a sight intended for AKs--even airsoft ones--will be far too low for an ARs front sight.

As for not focussing on aperture or peep sights, you're not supposed to (or be even physically capable of). They're supposed to provide an almost subliminal circle to centre the front post in, not a crystal-clear image.

I know you specifically said no shooting advice, but I'd recommend you stick it out and learn to shoot a peep accurately. This may help, and if it doesn't, it at the very least describes one of the mechanisms by which peep sights are more mechanically accurate than notch and post/tangent sights:

After trying off an on for over 30 years, there comes a time to throw in the towel.
