Where does the front sight mount on an AR with the Gas block rail? On the gas block or behind it up on the rail even with the rear sight? Thank you.

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 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.

You can mount it either place but mounting on the gas block will require you to raise the front sight post to account for the difference between gas block and acc. rail height. Mine is mounted on the rail.

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.

Hey Jeff, Not sure what exact gas block Stag Arms is using. But, I can tell you that I had to shim this front sight on mine. I have a Red X upper, received it about 6 months ago. I was a little disappointed that I had to shim the sight to get a snug tight fit. But, it works like a champ now.

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.

I couldn't honestly tell you if it will clear a "triangle gas block" cause all I can think of as a triangle gas block is the front sight and gas block in one. If that's what you have I again couldn't speak to the compatibility of this scope mount with a actual front sight seeing as I have a flat top. I would how ever recommend a 45 degree off set scope mount if you have a front sight, and add a rear sight and your red-eye to engage down range as most any distance. If I hadn't gotten the flat top that would have been my set up of choice. Happy trails and may your bullets always go bang.

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.

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.

It can go to top rail some guns .and ar have a riser on them it does fit on top flat rail but for me to see good through it .I had to raise the rail 1 inch but we'll worth it for the price and cool looking

I'm not sure what you're talking about here, but these sights have nothing to do with the gas block. These sights mount on the top or side rail and locate the "sight" at a 45 deg. angle thereby clearing the scope.

What "just me" said is true, but you would need or want a long picatinny/weaver rail. These sights, the rear, typically mount on the back of an AR flat top and the front on the gas block,they have to be on the same plane, you have the same distance between them as stock iron sights, usually with a scope in between. Mounting them any closer could possibly pose sighting in and accuracy problems.

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.

On my AR I do not have Iron sights but you can see through under the riser though I do not think there is enough room to see Iron sites, Sorry Bob

I have it set up on my AR and it has it's short comings. I would prefer the sights to be alittle higher. If you're not running back up iron sights then it works great.

Most likely BACK to the top of the Pic-rail. These sights are INCREDIBLE! I have mine on my Olympic Arms OA-93. Top-of-the-line accessory for a top-of-the-line firearm!Enjoy yours!

i haave a "henry" rifle ( in .22 rimfire ) that was pre drilled on top but it came with iron sights . i bought a rail with a 3/8"dovetail onit . problem was it had slots milled perpudicular on top . i purchased the accushot clamps you ask about , but the answer is yes it does . but i had to sift it forward or to the rear so the cross clamp bolts are located towards the bottom and i had to sift it so the bolts fit in the slots (slots are every 1/2" or so no troubles with eye relief . they are solid and i love them . i hope this helps .

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.

Your AR will need to have a rail already to mount this. Honestly though the eye relief on it is so short it'll bang you in the eye every time you fire. Also since it lacks a reticle you have to mount it behind a red dot sight of some kind.
