is this sight for a rail mount or a gas block mount?

Hey Richard, it should mount on any picatinny or weaver style rail. I am using it on a UTG low profile 4 rail gas block. What are you wanting to put it on?

I used it for a rail mount. I believe you have to use the high profile for a gas block.

It's for a rail mount. That's what I have, at least. I know your issue, though. Some are advertised as gas or rail and end up being the opposite. But this one is a rail mount as well as being a very sturdy one, too. With that said, it's still better to save your money and get something like Magpul Flip-ups. This one will work but Magpuls are very high quality and will last a long time. Get this item for a quick change out. If you get Magpuls, don't get the PTS stuff, just the strait up Magpuls that run about $80 to $100 for a set, it's money well spent :)

It's a dovetail style rail. The laser sight I bought is a NcStar Red Laser Sight with Weaver Mount.

yes...I have a DPMS as well, and that is why I got these. I am assuming that the gas block is also lower that the handguard and/or standard rail. These are very functional and work well with optics installed, quite decent.

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.

The front sight is secured on the picatiny rail. Its not good on the railed gas block as it gets to hot if you have a full length quadrail it is the perfect 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!

Depends on the height of the mount. This is roughly the same height as a standard gas block front sight

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.

Any front sight will work fine. I use the stock M4 gas block/front sight. I can look through my red-dot and sight righjt through it. If the red dot gets broken, I can pop it off and use the Matech and stock front sight. Works great.

I dont remember the height, but it works great for rail mounting and WILL NOT work if you want to put it on a low pro gas block.

No, these sights work best with monolithic style top rails that are the same height, or where the pic-rail on the gas block is flush with the forearm rail or at the same elevation as the upper receiver rail. If your pic-rail gas block is lower than your receiver, it will likely be too low to adjust the elevation high enough.

The instructions I kept didn't indicate the type of rail/compatibility, but I think they are Standard Dovetail. I removed the rails from my pistol because I don't have an added sight/torch. I think the pistol looks better and is lighter obviously. Sorry I couldn't help more.

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.

It was designed for the gas block rail that sets lower in height than the standard height rail found on any AR15's upper receiver. Assists in providing the proper height to your front sight picture for proper alignment with your rear sight. Extremely useful for standard DPMS upper receivers with a gas block rail that is not of the same height as the receiver's rail. Worked out very well for me. Hope that helped.

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 only takes up 2 flats and 1 slot. If you're gas block is lower than your rail you may want to mount it further toward the buttstock end. It will be stepped down otherwise and you may have trouble zeroing. The idea being both front and rear sight mounted parallel to each other.

For the rail you only need about 1 1/8 inch. So if you are attaching to a low pro gas block need will need it exposed, when folded the measurement is 2 inch total unobstructed. By the way, I love these sights!!
