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

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

I am using this product on my AR 556. With a rail gas block. It works very well any rear site apature will work but if you are going to be using a scope ever I would suggest the low profile black hawk flip up rear site.

If you bought one that is for gas block height then it will work fine. It will work with any AR15 rear sight.

This is the correct hight to be installed on a gas block and work with other rear sights. (some front sights are shorter, so they are made to be mounted on the top rail of the hand guard) I used this with a magpul flip up rear sight, but it should work with any rear sight you choose, as long as you mount it on a glass block.

This should fit if going on a gas block and not a rail. You can use just about any rear flip up site, I have a mid-west and mag pull.

If you have a flatop or low pro gas block you will be good to go. If you have a front fixed sight you will have sight picture issues. If you have a fixed front sight buy a low pro gas block and have the front sight switched out.

I would think it will work, the rail is the same. If it sits higher on the gas block you may have to shorten the sight pin if you are sighting in for longer ranges. I use a UTC red dot for close range and have my iron sights set for 100 yards.

It will work if your current front sight is staked in. It will not work if your front sight is in a dovetail.

I would say so. I think the 556s come with this sight anyway. But if you wanted a more reliable sight, I would go with something like an aimpoint. But if you are just plinking at the the range or dont have the budget, this sights works fine.

Yes, there are a number of different gas blocks available for the AR 15 style rifles. The most popular is the M16A2 post sight, that also incorporates a sling ring and bayonet lug. Just google photos of M16, M16A1 or M16A2s, Also, any gunsmith can swap out any style gas block.

I'm not sure Jack. Not sure how it will line up or how it will co witness, if at all. I wound remove the front sight all together but that is just my preference. My AR came with no sights because I wanted to put my own on.

I had my gun smith install both.He has a jig to drill the holes for the rear sight. Drilled and tapped. And the front sight was welded on. Let a pro do it on this one. It will work and look great.Regards.Helmut1*

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.

I had a bolt-on muzzle brake on mine. It clears just like a factory front sight. I noticed no change in the height of the front sight.

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.

I have a standard height/low profile gas block paired with a YHM flattop upper receiver and the alignment is perfect. I don't think you have anything to worry about if you go with Troy or MI sight pairs: there're the best! I really like the HK sights, very accurate n my AR. I purchases a lower cost return and am very glad I saved 20 bucks!

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!

I put this sight group on my S&W; 686-1. Worked out great. If your front sight is the same shape and size as the one pictured. It will fit with just a little filling on one corner of the sight. Add a drop of locktite to the clean oil free surfaces.

I have no idea. You might contact UTG and give them the make and model # of your front sight and the make and model # of your red dot sight and ask them if it would co-witness. Otherwise, just order the UTG 5-slot QD adapter, try it out with your red dot mounted on it, and if it doesn't co-witness with your front sight, send the UTG 5-slot adapter back for a refund.

As long as your gas block and upper receiver are on the same plane. If your gas block is a quarter inch lower you will need the sights specific for a lower gas block

I dont know but the sight fit right on with no trouble at all and it made a huge diffeance in the gun. I also bought the rear sight for it also and it fit right on also both worked excellent on the gun and was a huge improvement on the gun. If anyone wants to save a little then the front sight should be your first swap out.
