I am trying to figure out what do do for a rear iron. Should I get an elevation adustable, or a Fixed such as a Troy. Also, does changing the aperature on a Troy or DD change the zero like it does on an A2 sight. Thanks.

I have both the Troy and the LMT (which is an A2 sight without the carry handle), really can't say I prefer one over the other as their both nice units. I just IBZ them and forget about em'. I don't know about the second part of your question but as to which one you should get...I guess if you were used to the A2 sight the LMT would be a good way to go but either would serve you well.

1. I prefer the fixed elevation for the rear, just adjust the front sight for elevation, and the rear for windage.
2. Changing the aperature from the "Big" to "Little" or vice versa DOES change the POI. (I just found this out recently.)

Ive been look just as you have SAW
Are you going to add an optic then folding sights are proably want you want to go with, Im going with the Troy folding sights and an Aimpoint on my rifle.

I am a fan of Troy folding sights. I would go with simple as sf3pox1 said earlier- rear-windage, front elevation. A.R.M.S has some folding polymer sights I would like to try out-I think they are 71L (model).
If you're looking for a non-folding sight, the Midwest Industries rear has served me pretty well so far.
For folding, I would go with Troy if you can swing it.
WRT the MagPul sights, I'm not sure how I feel about my BUIS being made out of plastic. BUIS are an all-else-has-failed option. Personally, I'd like to know they're GTG...and not be worried about if they warped, got knocked out of zero, etc.

only if you have a railed gas block. magpul advises against mounting their front sight onto a gas block. I have used a magpul front sight on a gas block before, but just for plinking at the range and it was fine. I would imagine during a class or competition with a high round count you might encounter some melting issues. I have since moved onto a set of Midwest industries flip ups.

haha that sucks, that's why I switched over to non polymer backup sights and the magpuls are now on the wife's sr22. a quick search yielded nothing. when I have more time I'll look for a picture.
I have a front folding alloy sight at the moment DD I think. Looking for something to tuck under optic. I dropped the dollar on the optic, need to invest more in the rear sight as well. Thanks guys, now I get to spend more money. Dang-it

Consider this: would you ever mount an optic in plastic rings or a plastic mount?

And we are ashamed to admit that.
1. Their products are junk.
2. Any reasonable human being has boycotted ARMS because of their bad attitude, and sue happy mentallity twords other firearm industry partners.

Not to mention the owner donated to coakley's re-elction campaign.

Maybe you work for ARMS or something, or just live in West Bridgewater?

I am sorry if my anti-ARMS views upset you, but that Company makes me upset with the shit they've pulled, mostly because they are fighting against fellow firearm community partners. It is pety and dumb.

I am not upset, and I do not work in the industry, and do not live anywhere near west bridgewater.
The research I will do. I just assumed where most everyone copies their mounts and stuff that they made nice stuff. Could be wrong. The suing I will find out in during he research. Could you point me in the right direction? Thanks

Here is a link to the ARFCOM where Magpul (DrDrake) says, JUST DON'T DO IT, THEY WILL MELT. This is in regard to the plastic sights on a gas block. Then they argue with him!

The reason a number of back-up sights for AR's don't recommend sight placement on gas blocks have to to with front sight post height. Many are designed for placement on rail height. The gas block height sight posts are higher by more than a quarter inch. Which is at the upper limit of height adjustment for the rail height post. You'll run in to the same problem using the gas mount height and placing them on a rail. You may be able to adjust range between an A2 adjustable rear along with adjusting the front sight for range. If you are heating your gas block to a high enough temp while shooting an AR, your accuracy with any average profile barrel while super heating deteriorates. A Heavy profile will limit this only a little. Short of firing a Final Protective Fire in the military. I see little benefit to letting lead fly with little accuracy or training benefit. Shooting drills for double tapping, failure drills, multi target engagement and shoot and scoot should not be super heating your weapon. As to what A2 sight. It would depend on what primary optic you choose. Whether you want to co-witness through the A2 sight. Or you want them down and out of sight. By definition, an A2 rear sight has a height adjustment wheel for elevation adjustment. You won't find a lay-down with a thumb wheel. There are other methods out there for rear sight elevation adjustment and the market is changing all the time. Some are easy to adjust, some are spring loaded to pop-up. Some are Steel, Aluminum, and polymer. On the Aluminum and polymer sights, most actually use military spec front sight post. As it's cheaper than making a new tooling. The sight housings are not normally prone to warping. Any of them can be damaged from a hard hit or drop. Look around at the range, talk to other shooters. Get some hands on on a few. Then, based on your needs and pocket book, choose some. I personally prefer get some hands on, before buying. Like many things. Not everything appeals nor works for everyone. Whatever you choose, just keep in mind, easy of use, reliability and use in all weather and light conditions.
