I intend to mount sights on a Huldra(Adams Arms) flat-top upper. Will front sight function properly mounted on the gas block?

Yes, if your gas block is lower profile. If it' s high profile, you can choose B00CW93B3K in Amazon.

It works for me. I have a gas block mount front sight as well in a co-witness setup.

to be right on a flat top AR you need a 1/2 inch riser 8 slot. Keep it right in front of your BUIS. Get it close to your eye. The small dot is wicked! Best red dot for the money! Youll be amazed

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.

I dont think so. This is for gas block height that is slightly lower than upper receiver rails.

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.

I use the same scope on my Adams Arms upper and it work s fine. I also put the same setup on my Colt AR and can co- witness the front post with no problem. Hope this hels you.

It should be okay. These were mainly made to put on railed gas blocks that are lower than the handguard rails. However, because the elevation is adjustable, they should work fine.

Although I have a riser, I didn't need it. Mine is mounted on the flat top rail on my M4. A2 front sight is not a problem; the reflex sight lines up just above the front sight post on mine.... no conflict using either sight. I did not use the riser; it actually interferred with my iron sight by blocking the A2 front post.

Should work fine-flip up is for low mount gas block, not "same plain", otherwise rear sight works with either.

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.

The sight you are looking at will only work on uppers with gas block. These are a tad taller since the gas block is slightly below the quad rail on a flat top m4. The front sight is also adjustable for elevation.

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!

It should fit just fine it only takes up about 3 rail slots, it would however, be a little bit on the bulky side if you were to mount it to the top of your gas block.

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.

I put them on the rail on my flat top and low profile gas block with no problems or modifications. It the picatinny rail is standard size it should fit.

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.
