I plan on ordering an AR that comes with a railed gas block to attach a front sight.  I usually us a pair of MBUS but being plastic, the front sight will melt if the barrel gets hot enough.

What are some brands/models to look at for a metal front BUIS?

Thanks

I have a set of Midwest Industries metal, flip-up sights that have served me well. I would recommend them.

First ask self if need BUIS.

If yes, does the gas block rail sit parallel to the receiver rail or lower?

Any proven cases where this has happened? Or just more Intenet lore?

I have MBUS on my 7.5" SBR. Never a hint of them melting, even after several mag du ps.

Could've sworn years ago when I put my rifle together with an AA piston kit that I researched and found that Magpul "didn't recommend" it. But, again, that was years ago and could've been BS.

For his purposes, he's probably right.

For me, there are different considerations.
1) My budget is limited, so I don't have best-of-all-possible optics on my rifle.
2) One of my reasons for having a rifle is SHTF - during which I may have no resupply, and irons are better than nothing if my optic gets damaged (or the battery is dead when I take it out of the case)
3) I am not a soldier, and I don't have lots of gadgets on my rifle. I have sights and a sling. I haven't got another use for the rail space

What he said. MOST of us won't be putting $1500 ACOGs and other top-of-the-line optics on our rifles, so an extra $100 on top of a less expensive optic should be seen as a "you need to do it" by all the gear queers here. If I'm using a less quality optic on my rifle, shouldn't I have something to back it up with?

Not that I diaagree, but please explain how a gas block railed sight is better then one sitting on a high quality free float hand guard?

Ive had both a and prefer the hand guard mount over the gas block. Less wight, longer sight radius.

That gets back to is your gas block the same height as the rail?

If not, like the gas block in this pic, an MBUS wont work.

The gas block height is important. Some are not even with the receiver Picatinny rail.

In the pics I'm seeing it looks about .25-.5 inches lower than the upper's rail.

How do I make a front sight work?  What are my options without replacing the forend?

You need a gas block height front sight which will cost $$$. Just replace the whole thing with a YHM folding front sight/gas block or don't buy a retarded rifle in the first place.

Already bought the rifle.  It seems pretty well liked for what it is so not sure retarded is how most would describe it.

EDIT: I see a bunch of options for folding and non-folding "gas block height" front sights.  Most are cheaper than the Mbus pro front sight.  This doesn't seem to be a huge issue or am I missing something?

Thanks
