I was wondering if anyone has put these on an AR. I recently aquired an M4 style carbine and it is my first AR style rifle so I'm pretty unfamiliar with it. I think the guy who built it used some pretty decent quality parts, but he neglected to put on a set of fixed sights and instead just had a scope which was mounted on a raised rail, which I didn't care for and am going to use on something else. Anyway, my question is are these MBUS sights any good? I will eventually put a dot on this thing, and would like for it to cowitness, but due to the fact that it has a heavy barrel with no front sight post I need to mount the front sight either on the gas block (which might cause heat problems?) or at the front of the handrail.

Here is a link and some poor quality pics. Any advice will be appreciated.

I have the Magpul rear flip up sights and really like them. I have heard good things about Troy flip ups also but they are just a bit more $$$. Some sights offer price cuts/deals if you buy both at the same time. What kind of AR is that? I could not really tell what the symbol was on the lower.

I am rocking rear MBUS, under my scope. I had a fixed Daniel Defense rear before which was much more sturdy but for the price, magpul has made an excellent site.

To answer Kaiser's question, the lower is an older Lauer with the SML prefix, so it's an LMT. The upper and the adjustable buttstock are Model 1. I have been perusing Model 1's website and found some other options for sights. I might even end up putting a sight post on the barrel. Has anyone around here done that?

I have some on my MSAR.

I like them. They're pretty solid, don't cost an arm and a leg... they hold zero alright.

But they're called BUIS for a reason. They're def. not meant to be one's primary sighting instruments.

The Magpul front sight (which is made from polymer) can not be used on the front gas block because the heat will cause it to melt. I went with a Mid West Industries folding front gas block sight. (made of aluminum) Works great!

Troy BUIS all the way.

Arent these flip up sights made out of plastic?

Arent these flip up sights made out of plastic?

Yes and no.

They're pretty much made out of the same weapons grade plastic as Glock grips and such.

I have used the rear one for a backup to my aimpoint. I like it. However unless you are going to use a red dot or some site like that I would recommend getting a fixed BUIS instead of one that flips up and down.

Forget the mbus and go Troy it's worth it. They are tougher and Work better.

Just picked up my new CMMG AR and put the rear on it, couldn't get the matching front because of my gas block but I like it a lot. Definitely feels just like the polymer on a Glock.
