Is the sight height-adjustable? My gas block sits about 1/4" lower than my rail, so I'm not sure if I need a gas-block type.

The front post is adjustable for elevation but I don't know if you can get enough compensation for the difference. The best bet is to take it to the range and start at 25 yards. You may need a taller front sight.

Not adjustable to the extent you need it. I would look for a different height sight or you can get a profile riser mount (UTG sells one for about 8 bucks, and you can get them in different heights). Hope this helps -

It's adjustable, but only for elevation, I doubt 1/4". I bought this for a friend so don't have in front of me to check for sure?

I use this sight on a mini 14. The blade is adjustable for height. The sight sits on a picatinny rail mounted on the rifles barrel, this sight is the high sight. I believe they sell a lower type sight that accounts for the front a rear rails on a AR-15 being of equal height. My rails are not of equal height, my front rail diffenitly sits lower than the rear. They both match, I used a laser bore sight to adjust them with.

Its designed for lower profile gas blocks. It will stand too tall on a rail height block.

It does, but you will need to lower the post as low as possible before sighting in. Works best with offset gas block rail

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.

@jjnew It is too tall, and that ticked me off too. Instead of returning it I chose to get a 1" riser for my rear sight aperture to accommodate for idiodic sizing. Hope this helps.

The gas block is way to short to attach this to. The riser rail is approximately 6 inches long where it attaches to the rifle.

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.

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!

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.

The sight sits kinda high above your rail, so yes, you should be fine. Mine has a flat front gas book and so front sights would not be an issue for me. It may be visible if you have a raised front gas block, but should not obstruct your crosshairs.

I have mine attached to the gas block, It depends if you have weaver/pic rail on it

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 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.

No. Keep it on the rail, don't put it on the gas block if the gas block rail is lower. Your sights won't line up like they should if you do.

From the top of the rail to the top of the sight post is 1-5/16". It is adjustable. I use mine with the UTG flip up tactical rear sight. Mike's answer is also helpful. It took me 3 set's to find the right one.

This is four a normal gas block height.. ie one that is slightly lower than your other rails.

Richard, I own a DPMS L308 and the gas block rail sits about a half inch lower than the rail on the upper receiver. I remedied this by purchasing a riser rail from here on Amazon. Search for the UTG Low Profile Riser Mount with 3 slots by UTG: UTG Low-Profile Compact Riser Mount, 0.5" High, 3 Slots This should fix the problem if the gas block Picatinny sits lower than your upper receiver rail. It did on mine. Because the front sight was too low. My shots were hitting about 4-5 feet too high at 100 yards. This fixed the issue.
