AR-15 Flip-up sights

[Jadecristal]

I have a Bushmaster M4gery. I removed the upper carry handle, and put an EOTech on, but would still like flip-up iron sights. Does it *matter* which ones I get? If so, or if not, what's recommended?

there's a good sticky thread on arfcom reviewing, comparing, and contrasting all the BUIS options. dig it

one word TROY

Troy for folding BUIS, Larue for fixed.

Just remember that these flip sights are called BUIS - Back Up Iron Sights. You wouldn't use these for precision use, but mainly as a back up to your primary optic. That said, most of the BUIS rear sights (ie: Troy, ARMS) do not have elevation adjustments and only windage adjustments. If you have a fixed A2 front sight, you won't be able to adjust for elevation if you get a Troy or ARMS.

But if you have a low profile gas block, you can get the Troy flip up BUIS front which does have elevation adjustments...

I ended up getting that Rock River arms rail mount that covers the whole rail and raises the EOTech up a little. The fixed sights are pretty good and have full adjustments. Only downside is it obscures the lower portion of the EOTech view. Flip up sights might give you a more open look. Mine works good though.

I just bought some front and rear flip-up Mangonel sights from DPMS for my DPMS flat top just in case for some reason my scope goes haywire....haven't put them on yet, but have heard they are really good..

A BUIS made by ARMS, Troy, LaRue, etc, are all going to require an extra height front sight.

 

[Bartholomew Roberts]

They may require a higher front sight post due to the different sight geometry. Some people have a problem, some don't. A normal height front sight post will be adjusted until it is almost out of the front sight base if it does work.
