Is this for gas block or top rail?

I have mine attached to the gas block, It depends if you have weaver/pic rail on it

I have it on my gas block, the elevation adjustment would not drop enough for the uphill range I use outside of town. It seemed okay on the rail for more level firing and closer shots. Hope this is some help.

Either on it fits as long as it's a standard size weaver rail you have on your gun top rail or gas block with weaver rail

You could but it would over hang by a lot, this is about 5 inches long total(if memory servers me right), and the clamping area is maybe 3 and a half inches of that. Again not sure why you would mount a 20MOA rail to a gas block, but that is your call.

It clamps onto the barrel and strut using two screws. The strut attaches to the existing gas block using a set screw.

NO. it is for an uneven gas block. This MI front iron sight comes in two models. One is for gas block height and the other is for upper receiver height. If your gas block is the same height as your upper receiver this one will not work, it will be too high. check out midwest industries web site and you will see the difference. The one you will need is #MI-LFFR Low Profile Flip Front Sight, locking For use with railed hand guards or gas blocks the same height as upper receiver. When folded, super low profile is only .437" off top of rail. Or any other one as long as it does NOT say for gas block height.

This should work on most AR configurations. However, when I switched to the Adams Arms Piston setup, their gas block rides higher than stock ARs. So, as long as you are not running a piston gas block which is larger and taller than standard, this should work.

It only takes up 2 flats and 1 slot. If you're gas block is lower than your rail you may want to mount it further toward the buttstock end. It will be stepped down otherwise and you may have trouble zeroing. The idea being both front and rear sight mounted parallel to each other.

Yes. Exactly perfect for the F A2 front sight post. Picatinny railed gas blocks are not the same height though and you would have to use something else. It also works on Free float rails.

The front sight is secured on the picatiny rail. Its not good on the railed gas block as it gets to hot if you have a full length quadrail it is the perfect sight.

I believe this is for a gas block. I also purchased the MI rear folding sight as well. Both work great together!

I mounted mine on my flat top, and to the handguard mount, not the gas block. I have not had any issues with sighting in or holding a zero.

No, but you can put a riser on the gas block. Yankee Hill makes a riser for that specific purpose.

I used it for a rail mount. I believe you have to use the high profile for a gas block.

as log as the gas block rail ad the upper rail are in the same plane it should work

You can mount it either place but mounting on the gas block will require you to raise the front sight post to account for the difference between gas block and acc. rail height. Mine is mounted on the rail.

You're right. It's designed for a low profile gas block sight. I mounted mine on a UTG quad rail gas block and it's perfect height.

Absolutely not! I bought a pair and my gas block is approximately 3/16" lower than than the receiver rail and, after trying all adjustments possible, I could not even come close to getting any type of accuracy alignment I then tried user a 1/2" riser on the gas block and the same problem arose due to the front now being higher! The gas block and receiver rail MUST be virtually 100% identical in height!

Im sorry. I forgot to mention that this sight is intended for low profile gas blocks such as the type on the model 3 stag arms. The low profile blocks can be recognized by the gas block rail surface will be lower than the sight rail surface on the upper of your ar.
