Will the sights line up with a gas block that is lower than the receiver rail?

No. You do not have enough run out on the front sight, front & rear have to be very close to level,at differnt ranges this hight will realy come to bare.
1289895
Absolutely not! I bought a pair and my gas block is approximately 3/16" lower than than the receiver rail and, after trying all adjustments possible, I could not even come close to getting any type of accuracy alignment I then tried user a 1/2" riser on the gas block and the same problem arose due to the front now being higher! The gas block and receiver rail MUST be virtually 100% identical in height!

That depends on how much lower it is. The front sight is adjustable for elevation, but there are limits.As these are 45 degree sights, A lower gas block will effect wind age as well. There is much more adjustment available there, so they should work.
1289897
These have some adjust ability but if your gas block is much lower than the receiver rail I do not think they will line up to give you a good sight.

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

I wanted to mount front sight on gas block rail too, tried it, but mine sits lower than the top rail so alignment was a problem. Checked it with laser bore and way off. I have collapsible back up sight at the end of my top rail so that space is spoken for.So I mounted mine on the top rail right behind the front back up sight, rail even with the rear sight. The rear and front are fairly close together. I'm limited on rear sight location due to scope so I'm about 6" from peep hole to pin on the top rail, but they line up pretty good with laser sight. I would use for 50 yds or less. Still need to sight in with ammo but it's 4th in priority.

as log as the gas block rail ad the upper rail are in the same plane it should work

My gas block is the same height as the forward rail so these work great. If your gas block is lower not sure if they will.

Yeah, you should be fine. Ghost ring sights are a little higher, but there was plenty of clearance.

Sorry for the slow response, had to look up your gun. It should fit fine on the lower rail. It can be set-up to collapse to the rear or forward.

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.

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.

You should be able to keep and use the front sight. The Samson rail tucks in under the lip of the gas block.
1485425
it should be fine. it's not completely tall enough, but with a scope the worst you might get is a slight blurring of the sight at the bottom of it. most likely you will not see it. I eventually removed the front sight block and but a gas block with a short rail section on, I wanted offset sights so I could tilt the rifle and use iron sights if the shot was to close.

Won't be a problem at all since you can remove one side of the mount on the sight. Remove the side and place the sight where you want on the rail then tighten back down.

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!!

Yes, but it will leave a small corner of the saddle protruding above the frame of the receiver near the safety. This can be filed off to match, but it was not significant for me to bother with. The shells hide the small protrusion, anyway.
271488
no, it won't. However, my clone was built without a rear sight and i removed the front sight and replaced it with a low-profile gas block in order to use a longer forearm rail system. didn't need the iron sights as this scope has them built in above the optics. zoom in on the pic and you can see them. these sights are way better, in my opinion, to the iron sights that are usually found on ar's.

Yes. Exactly perfect for the F A2 front sight post. Picatinny railed gas blocks are not the same height though and you would have to use something else. It also works on Free float rails.

Yeah it should. Mine was a stock sight post/gas block and the mount worked like a champ.
