The rear sight can't get tightened on my AR-15. Tried all slots w/o luck. What's up with it?

Lube the threads and work it a little. Mine was the same and it tightened right up. Works fine now.

Maybe you got a lemon. Mine was tightened the way it should be and was secured by loctite. But mine arrived with visible toolmarks.

Check out the pin underneath the sight and also check to make sure you are aligning in properly (which I'm sure you have). There are only two other options after that if it does not work: 1.) Try to get a new rear sight or 2.) Maybe...just maybe, the picatinny rail you have is not compatible with the sight. Although if that were true then you would probably also be having trouble with the front sight. Good luck...

Didn't work for me either. Sitting on the shelf doing nothing ... a monument to a crappy product and the seller won't answer any emails.

Personally did not have any problem you might want to return it for another.

Is it possible that the allen screw has been over tightened? That is the only thing I can think of that would result in your situation. If this is the case you can either try to use thread tape or a piece of string soaked in lock-tite to provide some "Traction" for the bolt threads. A slightly larger size bolt may also work in the already stripped threads. Good luck!

No idea, I did have to crank on mine pretty hard to get them fit snug but they did eventually tighten, forgot about that.

I think I'd send it back, must be out of wack from the factory...I installed a set on my KSG and they both fit perfectuly

I installed a set on my KSG...flawless install..really easy...I'd send back, must be a bad unit from the factory

I did not get my sight on perfectly straight. I have yet to get it to the range to see if it is good enough. My last sight had the same issue, so I'm not inclined to blame the sight. You might want to have a gunsmith stick it on for you. You might have better luck if you have a gun vice. I was afraid to use a vice myself. Well, that's my story.

Hi Victor. That is an excellent question, but I'm not 100% sure. As far as I know, the Troy Rear and Front sights should line up correctly, but I'm not sure about your rail setup. I would take a picture of your AR and send it to Troy, they are very helpful and can tell you if this Rear sight will work or not.

I own a Colt M4 carbine and I have the M2 front sight. It's factory and I don't want to mess with it. I have a Trijicon and a Bushnell sight, and ordered the UTG-1" adapter rail because the front sight was too high and the ACOG sight was not working. The 1" seems to do the trick for both sights, but I have not been to the range yet. That will tell the story, but I'm sure the problem was solved with the adapter.

My ar has a smaller red dot on it. I also have a foregrip. Had to remove it to get the rifle to fit, still a tight fit.

I have used to put on/remove Ar-15 barrels and have had no such issues. Return it if possible. If not try the ones at Harbor Freight that are the same thing for half as much and even less if you download a 20% off coupon. Right now they are on SALE: http://www.harborfreight.com/3-8-eighth-inch-drive-click-type-torque-wrench-807.html?ccdenc=eyJjb2RlIjoiMzk2NzQ0MzIiLCJza3UiOiI4MDciLCJpcyI6IjExLjk5IiwicHJvZHVjdF9pZCI6%0D%0AIjMxIn0%3D%0D%0A

I never attached the sights because i was missing some of the screws. Despite not using the sight, ive been shooting pretty well. I'm sorry i couldn't be of much help!

Your scope or in my case reddot does the tightening, this piece is just sandwiches in. Got mine on a 22 leveraction and the kids have been shooting it alot squirral hunting and at the range with no problems.

Sorry i also has to return my back for a refund because it doesnt fix on my ar-15 picatinny mount. They send me a difference ring mounting scope then the one in the picture.

Sorry I am so long answering this. I do not see how this is possible... not unless the front sight is also rail mounted, elevation equipped, and the correct height to match the rear unit in question.This sight is specifically designed for the AR-15/M-4 platform and IS NOT ELEVATION ADJUSTABLE. There are so many better options than this... keep on looking.

I think there might be a small gap where it tightens so getting a mount that tightens on both sides of the barrel might fit better. I hope this helps!

There is a small gap at the rear of my frame where the grips meet the gun. If it's wrong grip send it back and go to gun shop to try some on.

I put the Strike fire on my AR-10 and went out of adjustment within a 100 rounds and cant get it back on. I think it shook itself apart on the inside. need to send back

Josh, I would be concerned about the portion of the stock at the top rear. It looks like possibly a sling attachment. the recoil pad fits snugly around the end of the stock and that may force the fit.

Try adjusting the sight all the way in the opposite direction to see if there's anything caught in the threads that are exposed. If not, inspect the threads, they might be defective or dinged up. If so, return and replace. Don't give up on it if you got a bum one, mines been rock solid!

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.

It's not as easy as if you had an actual ar15 front sight block but it will work. You will need a big hammer and a steady hand. Also remember its a tapered pin so be sure to check which side is smaller and knock it out from that side. Also putting a piece of 2x4 under the receiver will help steady the gun.
