I guess a better way to ask this is "Is the location of the gas block mounted front sight the same as M4?
347443
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 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.

It depends on the hight of the gas block. There are different size sights based on the hight of your gas block.
347447
Yep! M16, A1, A2, M4, AR15, A15,are all similar and are generally in the same location. Some gas blocks have a bayonet tab and sling ring while others do not. Call a local gunsmith about your specific situation. The sight shown in the photo here is the one I purchased and it fit perfect on my picatinny top gas block.

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. NO. it is for an uneven gas block.

I have both, and the rear sight and the front face different directions because of the height of the gas block. The front will face the barrel, and the rear will face the charging handle. If I had it to do over again might have went troy or Magpul now has metal but they are very good Bus sights expensive but good!

the question is strangely worded. The sight is meant to fit on top of a gas block that is at the sane height as the rail on the upper receiver.

Yes, that is the gun I put it on. It works well, I keep it in a safe and check it monthly and the sights are always illuminated.

Yes. Bigger in diameter and brighter for that reason than other night sights. Front sight is taller than factory sights. I like mine very much

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

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.

Not necessarily but you probably won't know until after the install to see how it shoots. I put this one on because the original front sight post was too high and this fixed the problem.

Not too sure about this, it depends on what type of mount is on your M4.It aligns fine with my Aimpoint PRO in the factory mount, the center of the optic is around 1.5 inches above the top of the rail.Hope this helps.

Kind of depends on your rails. I'm not sure about this combination, but when they are wrong it is about 1/8" off on the height which is pretty obvious. My front sight mounted on the gas block which I think made it too high so I had to get a lower version. I think if your rails are the same height front and rear they work together. I don't have my rifle in front of me.

Absolutely. That's what I'm running right now. I have a railed gas block and the original and gen2 Mbus sights are not compatible as they are primarily polymer and will eventually melt on the railed block. The Pro series is all metal and is safe for use on the railed block. The gen2 Mbus rear I have lines up perfectly and saved me a good deal of money over buying the Pro rear. Note however that the Pro series are not "pop up" sights and must be flipped up manually. I'm currently running the gen2 mbus rear, the pro front, and both are co-witnessed with my Vortex Sparc II red dot. Very happy with the set up. Absolutely. That's what I'm running right now.

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.

It co-witnessed fine (absolute) with an F marked A2 front sight post (PSA upper) and Matech BUIS rear (should be same height at MBUS). It also co-witnessed with YHM flip up (gas block & sight) as well as with a MBUS front- both with Matech rear sights. Hope this helps. Good luck.

It works for me. I have a gas block mount front sight as well in a co-witness setup.

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!

Maybe you're looking at the E-mount version? Also, this appears to be the wrong photo. I own one and it doesn't look like the one in the M4/3 version of the photo.
