There are two heights for this sight -- "normal" height and "extended" height. The normal height is used where the front gas block is in the same plane as the rear rail on the upper receiver on the rifle. The extended height is used when the gas block is lower (about 1/4") than the rear rail.

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.

I really don't know for sure since this is the first set of sights I've purchased and installed for my standard M&P.; You should be able to find out quickly with a little bit of research on the matter.

I'm not sure, I bought a green dot but it didnt fit, make sure the rail for the red dot is the same length as the measurements of the rail on the smith & Wesson.

Probably. I put mine on a M&P; 15-22. I used a 1/2" riser as well to clear the factory sights.

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

The height of the sight from the top of the rail/gas block is 1 9/16". This low profile sight is great if your gas block (mine) or front rail is the same height as your upper receiver. If your gas block is lower then you need the normal height sight. I hope this was helpful.

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.

It will fit but the front sight will have to go at the end of the receiver rail not the gas block rail. I have as a stag number three and the sights are perfect for me.

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!

Works great on my S&W; M&P; 15 w/ same plane gas block. dont know exact height but I paired it with UTG Model 4/16 Complete Match-grade Rear Sightand it seems to be a great match. As stated in one of the comments on posting for this sight, rear sight is significantly to the left side when sighting in, not sure why but thats how it is. and the post needs to be pretty far down into the front sight to get the correct position. Love this setup!

I would get the Diamondhead front sight hi base gas block for using on the gas block rail. I it is made for the gas block rail.

If you have a Gas block on the same plane as your receiver rail, this sight will not work. Its for a gas block that sits lower than your receiver rail.

This sight is designed to work with the standard "A Frame" Sight. So long as your front sight matches that height, you should have no problems. BE CAREFUL when selecting front sights, as there are two separate standards, one that fits a gas block, and one that fits a straight top rail.

Just so you know the A2 Front Sight has been discontinued. Not a big deal as it is a great Front sight and will last for a very long time. To answer your question. I don not have a DPMS Oracle to compare the sight allignment. What I can say is that all the sights that fit the AR have a standard height. With that being said as long as your gas block is the same level as the upper it should fit fine. The rear sight you are asking about does have some elevation adjustment and more than likely can be adjusted if there were slight differences. Not a definitive answer but I think you will be OK.

It will fit and all you need is the sight and included pin along with a punch. If you put it on correctly it should be perfectly zeroed already. Also be careful with the pin it is easy to bend and mar up.

Yes, it fit mine. The only issue was that I have a reshaped bolt handle so I had to grind away some of the material to make the notch deeper. Works fine. Only other issue is that you really need to get your face into the stock to properly see the sights, but once there it works fine, and seems to have reduce recoil some.
