I saw a good deal on a Matech rear peep sight, so I ordered it. I have an HK style front sight, and was thinking of replacing the HK drum-type rear sight with the Matech, as I like the HK front sight.

However, I have a feeling mixing and matching sights is not conducive to good aiming. 

And if this is just a horrible Idea, what type of front sight should I go with? My favorite is the flared barleycorn found on M14s, and the closest I've seen for an AR15 is a sight put out by Daniel Defense.

As long as the sights are the correct size I don't see what the issue would be. Your personal preference is another matter.

What do you mean by the correct size?

 

Sorry, most of my guns just have built-in sights, so I never had to consider anything pertaining to sight differences.

There are different heights for front sights. Gas block height, rail height, and Sig style heights* I think

I have Matechs on the rear of my AR and like it. But I also have the standard AR front sight. Bottom line is I the heights have to match somewhat. Otherwise there would not be enough room for elevation adjustment.

Oh, okay. I have a flat-top upper, with a railed gasblock that is the same height and dimensions as the rail on the top, so that's fine then?

As long as the sights are on the same plane you should be GTG.

Yes you should be OK. Just don't put any poly (magpul) front sights on that block.

Unless they are the new metal ones.

Nah, for now I'm planning on sticking with my knock-off HK style, until I get some cash for the Daniel Defense one that I like because it's almost exactly like an M14 sight, flared sight-wings and all.

 

Also, is it true that the further apart the front and rear sight, the better?

Then they wouldn't be poly

Yes. I like the DD ones as well.

You know you are really gonna confuse the shit outa him....

However, over priced, I like the new front metal one. Has a dial to adjust the el... No more tools, bullets or otherwise needed.

Haha, actually, the one thing I did know was to avoid the polymer magpul sights. Friend of mine whose opinion I really trust on these things claim they don't hold a zero very well.

 

I sort of like the Troy, but I'm in no rush. I'll have to see just how my HK-style front sight is, and then determine from there. But I love the rear peep front barleycorn style sights.

I've never replaced any HK sights. But, as was stated, they need to be the proper height to match your front site. And the difference that can screw you up may be very small, you might not be able to determine it yourself. If you get it wrong it's possible you will run out of elevation to get your POI to match POI at desired range. But more likely, you can get POI to match POA at your zero range but bullets will be very high or very low at other reasonable ranges.

I'm not sure about the hold zero problem. There are a couple reasons. One of which they tell you not to do with the plastic sights is put them on a gas block rail because they heat up and could warp the sights. Other issues is putting them on cheap forearm rail systems that are loose.

My peeve even though I have a set is the plastic is just cheap crap. The Troy Dioptics are nice but not cheap. But you get what you pay for.

Provide the front is a same plane front, yes.
