Will this work on the gas blocks that are lower than the rail on the upper reciever?

No. Keep it on the rail, don't put it on the gas block if the gas block rail is lower. Your sights won't line up like they should if you do.

I'm not sure there is enough information to answer question because it will depend on the height of the rear sight and its rail. This is a short front sight. It would work if mounted on a high gas block rail with a high rear sight. I'm using it on a flat top with a free floating 10" handguard and a detachable carry handle, where I have a flat rail from the bolt actuator handle to the front of the handguard. If the gas block is lower than the rail over the upper receiver, this front sight will probably be too low, causing the strike to be too high.

No, This is is purposely taller to work for the lower gas blocks. If your gas block is level with the top rail, then you need the one that is not gas block height. This same manufacturer makes both. You do need metal sights for the gas block since plastic ones will melt. And these are metal, So just get the standard height sight. You will be ready to shoot.

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.

It depends on the hight of the gas block. There are different size sights based on the hight of your gas block.

Yes it will fit tightly to the gas block rail. I put this on my Stag Model 2 Gas Block. This version is for the rail height gas block.

I mounted one on an older model mini--I am not familiar with the gas block design on the newer 'tactical' model. Sounds like a 'accu-strut' question, sorry.

if the gas block is the same height you can used any kind if the front is lower you will need this one and any back will work

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 should fit just fine it only takes up about 3 rail slots, it would however, be a little bit on the bulky side if you were to mount it to the top of your gas block.

Yeah it should. Mine was a stock sight post/gas block and the mount worked like a champ.

It will not. The rail changes the dimensions on the lower receiver too drastically.

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!

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.

No, gas this sight is meant for a low profile gas block. You need a stanard height front sight.

It depends on the length of the gun but their the same specs. Most gas blocks are different in the way they are mounted some are "welded" some have set screws. But all can be changed for an A2 style or a low profile gas block. I hope this helps.

This one is designed for a gas block that is same height as a quad rail would be. If your gas block is rail height then yes it will work. The more common one that UTG has is for lower profile gas blocks. When you know for sure just order the correct one, you should be fine. Either one is designed to work with standard rear sight.
