is this sight for mounting on a gas block?

yes, it has a very strong flip-type action. (it won't lose its sighting adjustment ability after a few shots.) I've shot thousands of rnds with no problem.
1385912
yes it will. It is all steel, it flips open or close without a lock button.its is not bad for a range day, but would recommend something different if using as a le or military.

Yes if you have the gas block with the rail top. Just be sure to cinch down the nut without over doing it.

If you have a rail height gas block then mount it there. I like to have the sights as far apart as possible - I get better MOA.

I believe it will work. My rifle also has a railed gasblock and it works fine in mine.

You are correct, the A3 Upper is higher than the gas block. I had to purchase a riser for the front gas block to 'level' the sights. However, I still recommend the sights, just know that you need the spacer.

Mine did. My gas block was lower than my rail, so obviously I had to order the taller version.

No. It mounts directly to your receiver by drill tap. The front sight is attached over the original bead sight by epoxy.

Yes any Troy rear sight will be level with your front gas block mounted sight. The block mounted sight is higher than your standard rail mount to make up for the distance between the gas block and rail. Hope this helps, btw these are excellent backups.

I dont think so. This is for gas block height that is slightly lower than upper receiver rails.

This sight is designed to be installed on a gas block that is lower than the upper receiver. If you want a sight that is on the same plane (same rail) as the carry handle, go with UTG MNT-754, low profile sight (unless you do not think UTG is good enough).

I put them on the rail on my flat top and low profile gas block with no problems or modifications. It the picatinny rail is standard size it should fit.

Yes..this front sight is mounted on my gas block, and together equals the same height as a standard m-4 front sight. NOTE: The rail on my gas block is lower than the rail on the receiver, that is why I needed this standard front sight. {they do make a short front sight for full length rails} hope this helps. joe

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.

These do work very well for a flat top. I wouldn't mount it directly on the gas block. It's designed to be mounted on a picatinny rail system.

No I don't think so because the hight offset between the rail and the gas block.Call Troy and they can hook you up with the correct info. I would still get them off Amazon if you can, better deals!

It should be okay. These were mainly made to put on railed gas blocks that are lower than the handguard rails. However, because the elevation is adjustable, they should work fine.

I don't think so. The rear sight is designed to mount directly on the receiver after being drilled and tapped. The front is designed to be mounted over the factory bead sight.
