Is there a specific di-optic rear sight that mates with the gas block mounted front? Or, can I purchase the gas block front with any di-optic rear?

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.

Magpul doesn't recommend it. When I do mount a front sight to a gas block I use Midwest industries. They have a gas block height specific sight.

I do not use the rear site. it does co witness just fine. I'm thinking of using an eotech fr my front sites. over all... I'd recommend this site. works for my Kriss.

I have it set up with the traditional Glock rear sight and have no issues at all with it set up like that. Had it that way for a few years now and love it!

Don't know for sure. I bought both front and rear popup sights to mate with my Flat top upper and the"raised" gas block (to match the pop up rear sight on my new flat top upper). They aligned perfectly! I'm doing to do an upgrade soon to replace my Olympic A2 upper with a Flattop upper and although I've got a rear & front flip up set (I got FS & RS from Amazone for $22/ W free shipping. I think they're greart.) decide to keep my stock fixed mil spec FS. We'll see which option works better. question me in a month or so (Wish I couild jump on the "fun" stuff vs. 'day to day crap' right now, but can't.) I'll find out if the std Fixed FS aligns with the flattop popup RS W/I a few weeks. Remind me! Don't know for sure.

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.

It seems to depend on who answers the question. The sights I received are on the same plane and the front sight does not work with a low profile gas block. It seems that the order fulfillment companies are sending out each type randomly.

The sight should work perfectly with the A2 front sight. I have the same setup.

I mounted mine on my flat top, and to the handguard mount, not the gas block. I have not had any issues with sighting in or holding a zero.

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.

well also bought the mechanically fixed HiViz sights they work are are helpful. depending on if you have a rail or smooth barrel would decide the type but in either case the rail mount winds up being about 18" apart when targeted with a laser bore sighting tool. Its just slaps on but sighting is another store.

I wouldn't mount this to the gas block. The screws are probably too wide apart. This rail is typically used to tilt the scope down to increase the elevation adjustment. I don't know of any rails specifically designed to extend from a gas block.

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.

I have a DPMS Oracle. The front and rear picatinny rails are different heights. I had to buy a .750 raised gas block from Amazon to make it works. They will work if you do this and bring the front sight up to same level as the rear. Ivan N.

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!

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

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.
