Back up iron sights for a Smith&Wesson M&P15 Carbine

You can get the cool pictures part by posting pictures of the S&W M&P 15 for the rest of us

I rock Troy, YMMV.

A.R.M.S. is probably as good as it gets.
They invented most of the rail stuff for the military.
Heck, they even invented the rail!

GG&G MAD BUIS


My LE 6920 wears one

Troy or ARMS. I wouldn't look at anything else.

For folding: Troy for fixed: Larue.

Both are very rugged and require a tool to change windage. When I need a BUIS I want to know it's still zeroed.

Running an optic dosen't require folding BUIS. BSW

My 20" in C7 copy form:

I've never seen anyone put a BUIS in front of an optical sight before.

Interesting..

My m&p 15 came with a Troy two aperture flip up. Very solid. I don't have any experience with the others, but the Troy has everything I look for in a BUIS.

I use this Troy folding BIUS. It has a nice, compact profile when folded and co-witnesses perfectly with the Eotech when deployed.

I've used the ARMS #40 and Troy on my personal rifles and much prefer the Troy for a flip rear sight. If you want elevation adjustment in a folding sight then your options are much more limited; but since I can't really acquire targets with irons past 300yds usually given my eyesight, I don't worry about it.

Troy rules the roost in my opinion.

I really like the ARMS #40 with an XS Sight Systems Same Plane Aperture.

I use my BUIS iron sights at least as much, if not more than my red dot, so I like good sights.

Well, S&W ships the Troy BIUS on their M&P15T. They are nice. No complaints on mine.

i got a cheap *bent* carry handle for free from a friend and cut it down for the BUIS. works great and there's a write up on it on arfcom.

I also use the Troy BUIS and recommend it.

We built, low profile, and simple. No elevation adjustment, and you need a round to adjust the windage, so there's nothing for you to accidentally screw up when you need it.

Wayne, can you show some close-ups of that front sight?

I have a YHM backup rear sight for my Busy and I really like it.

Here's a pic of my setup.....

Stay away from UTG, I have an M&P w/ a 16" barrell and bought UTG front and rear BUIS for it. I was unable to get my rifle to zero with the BUIS' so I zeroed with my EO Tech first, then tried to get my BUIS to match the dot of my holosight. The UTG's would not adjust low enough.

Has anyone else had an issue with BUIS on a flat top M-4 style AR? I have tried a few things and can not get BUIS that will zero. I know that when using a detachable carry handle w/ a 16" barrel the front sight apeture must be .004 taller than a normal apeture (this is according to Bushmaster) but even with flip up front and rear I can not get the front sight post low enough, (and yes I am following correct 25 M Zero procedure). The gas block rail and reciever rail are the same height, is there a special BUIS config I need?
