I just got a Matech rear sight to replace the Magpul rear sight on my Sport. I haven't mounted it yet, but it seems like a really good back up sight. I like it because it has both elevation and windage adjustments. The adjustments move freely, yet not to easy where they would change by being bumped. They have a positive "click" at each stop. I know most don't believe you need elevation adjustment on a back up sight, but right now I have a cheap red dot. It isn't a matter of if my optic fails, but when! I also find myself shooting more with iron sights than optics on both my .22lr AR and my Sport. Once I have it mounted on my rifle, I will take some pics to post up and give a range report.

I purchased this from another forum member, oneyeopn. If you are interested in one of these, drop him a line. Good guy to deal with!

For those of you who have never dealt with the Matech, it is what the U.S. Military presently use for their BUIS. It only has one peep hole which is somewhere between the magpuls coarse sight hole and the fine one. For some reason it is actually easier to see through than the magpuls and will still co-witness with all your optics. It is the only BUIS with elevation adjustment and the Marine Corps still qualify with it to 500 meters.

That is the other thing I didn't like about the Magpul. When I look through the peep hole, it bugs me that the outside top edge is not round, but is kind of flat. When looking through peeps that are round, my eye naturally centers the post. The squareness of the Magpul throws that off for me and I have to concentrate on the inner circle, if that makes sense.
 
I learned something Yesterday, to sight in the sight, you put the lever pointed to the line and then sight it in @ 25 yards or meters, you are then sighted in for all the elevation adjustments.
 
I pulled an instruction sheet online and it says for the M4 sight in, align the sight to the 300 yd mark and sight in at 25 meters. For the M16A4, align the sight to the line on the elevation adjustment and sight in at 25 meters.

Thank you very much, this is good information to have...when I carried m16's they were A1's and the carrying handle didnt come off.
 
I sighted in on the 20yd line (my range doesn't have a 25 yd line...*** is up with that?!) using the 200 mark. Based on a thread on calguns.net I set zero at 20 yds about 1" low. When I moved to the 100 yd line I was pretty much on target and was able to keep the majority of my shots within a 6" circle. Considering that the 750 rounds I've put through My Sport are the only centerfire rifle rounds I've ever shot in my life, I'm pretty happy with where I am. What can I say, In USAF basic we qualified with 22LR converted M-16s. haha

All in all this is a great, solidly built sight and a bargain at the $40 oneyeopn is selling them for.
 
Just got my sight in from Oneyeopn and got to say thanks for the quick shipping! I was a little unsure about the Matech when I ordered it but for the value, couldn't pass it up. Now that I have it mounted, I'm VERY pleased with it. I hope to sight it in this week. It's a little dusty and has some fuzz but here's a quick look!

I just mounted mine this weekend...I didn't have the correct size torx bit, so my neighbor brought one home from his shop. No range time this weekend due to kid activities and weather. Hoping to get to the range to try it out. My range does not have a 25 yd. line that I can fire rifles on, so I am going to sight it in on the 100 yard range. With the sight set to the 300 mark, I should be hitting about 1.5 inches high at 100 when it is zeroed. And I will sight my red dot to being on at 50 yds.

The only drawback to this sight that I see is that the little nub that holds the sight down in the folded position will eventually wear. But for the price from Oneyeopn, these can't be beat.
 
Finally made it to the range and here is what I learned...

First, I need a range with a 25m line that will let me shoot rifles on it. My eyesight is not what it used to be. My plan of setting the Matech sight to the 300 setting and then sighting in to be 1.5" high looked good on paper, but failed in execution. The front sight was as wide as the colored areas on my targets. I used 6" and 8" colored circles and could hit the circles from 100 yards, but not what I would call a "group".

Since I couldn't seem to get a solid group at 100 yd, I was curious to see where it would hit at the 50 yd target. I left the setting on 300 and fired 5 shots. They were high, but they were grouped! So, I moved the Matech sight to the line marking and fired another 5 shots. Using the 6 o'clock hold sight picture, all 5 were in the 10 ring (2 inch circle). I was happy! So back out to 100 yds I went and again hit the circle but not a tight group.

A gentleman in the next lane had watched me do this and could see me getting frustrated, so he came over to offer me some advice.

1. It's a BUIS son, not a competitive target rifle sight!
2. It is calibrated for meters, not yards. While there is not much difference between 25 yards and 25 meters, it makes a huge difference at greater distances.
3. The Matech is designed and calibrated for using (I forgot what exactly he said) military fmj ammo, not the 62gr Silver Bear I am shooting. While it will still work, it will change the sight alignment.
4. And finally, Silver Bear is not going to group as well as other ammo. He didn't think there was anything wrong with keeping all 5 in a 6" circle at 100 yards.

Don't you love it when the guy shooting next to you is reasonable and reassuring?

With open sights at 100 yards it hard for me to tell if I'm holding at 6 o'clock, or moving up toward center mass. the black dots all get too fuzzy. haha.

I had the same issue. The front post was as wide as the target and I was as close to 6 o'clock as I could tell.

There was a guy a few lanes down shooting his AR at a B-25 silhouette. At first I thought that was a strange target to use, but now I understand why!
 
I just ordered one of these from Amazon...



I was reading where folks were having a much easier time using this with their BUIS as opposed to the standard front sight post. You do lose a bit of elevation adjustment since the sight only works in two of the four detent positions, but the crosshairs should make it easier to compensate.
 
Bill with the Matech, you should have all the elevation adjustment you need. One of the reasons for the Matech was the front sight post was a bugger to adjust for distance under combat situations.

p.s. I really like that front sight post, let me know how it works
 
I think I need a smaller aperture. I'll have to see if it's possible to fabricate an insert for it.
