AR rear iron sight question

[Bigtanker]

Just finished my first build. It has a standard Milspec (I think) front sight/gas block. I need a rear iron sight for it. I don't want to spend a bunch of money on it as I plan on getting a quality red dot at the beginning of the year. Do I need a specific height rear sight? Another INGOer was gave me a rear pop up but it was too short. Also, what are some good lower cost options (<$60) for the sight.

I just picked up a used MaTech 600 meter iron sight from a fellow INGOer. It's good enough for the U.S. Army and it seems pretty idiot proof once you get it zeroed.

You can find them used for much less than this price if you look around.

MBUS. Cheap and effective for a back up sight. Just make sure you buy from a reputable dealer. Lots of fakes and counterfeits out there.

Thanks. I'll look into this one.

The matech is the first sight that came to mind. Keep in mind it's gov surplus now so you can find them new on ebay for $50-60 to your door. You can find them used and beat up for less. I have bought several from ebay, and have them on a few rifles. The military does pretty thorough testing on gear before sending it to the field, so I'm confident that it'll serve me well.

I use an aim sports dual aperture rear iron sight and i love it.

Primary Arms has Ruger BUIS pretty cheap. I have never tried them but it is Ruger.

Rual King stocks them for around $50 IIRC. I need to stop at Midwest Gun Exchange and see what they have.

I just put this on one my ar build for the reasons you listed above. Has done well so far.

Good to hear. That one was on my radar.

I had one of these, and it seriously broke on my first outing with it.

I would stay away from the bargain bin / airsoft stuff. The Matech rear is hard to beat, and the surplus prices on them are great. Depending on how hard you are on gear, the Battle Arms Development claw and screw replacement are a nice upgrade, and relatively inexpensive.

If you're treating your AR as non-lifepreserving gear, why have a BUIS at all?

I want to get a good quality red dot for it next spring, when my wallet can afford it. I have no rear sight right now. I just need something inexpensive to use for plinking until I get the optic.

Just get an MBUS then. They're plenty fine for what you want. They're more than robust enough, and if you break one, you would have broken a metal one or rendered it useless anyways.

Need something better? Get the MATech or a Troy.

I took a carry handle, cut it off and trimmed for a rear sight. Military adjustments are automatic for me. I doubt I'll ever have to use my sights BUT if my Aimpoint M3 ever pukes it'll be nice to be able to fall back on them. Super strong and weight isn't bad at all.

Serious question, why run a red dot at all if you're absolute cowitnessed with a non-folding rear? Seems counter intuitive to me.

I run MBUS. Works well enough for my needs.

So your saying you can shoot just as fast with irons and no RDS? I know I can't

Is what I got for my AR. Really similar to the one posted earlier.

The red dot is the obvious sight point. I don't even notice the sights. I keep the front sight down and the rear sight is positioned half way between the large and small holes. No interference at all. They don't even show in the red dot sight picture but are there if needed.
I'm old fashioned and only have about 95% faith in the electronics. This is my #1 go to rifle I will trust with my life.

I have something just like halfmileharry. On one at least.

YHM BUIS are on the other three. On has a gas block flip up from them and the other one has a regular pair.
