Finally! I'm an AR owner now! And I have a question.....

[rondog]

Just bought a DPMS "mid-length" on Saturday, in beautiful condition. Seller said he'd only fired 92 rounds through it, and it looks like it. Looks brand spanking new. Has a scope mount/rail on top, and a Magpul(?) flip-up rear sight, came with the case and all paperwork, two stock 30-round mags, and four Magpul 30-round mags. $800 for the package.

It shoots great, but it's hitting quite high, and I can't figure out how to change the elevation on the rear sight. It has an obvious windage knob, but I can't for the life of me figure out how to adjust the elevation. At 100 yards it was hitting about 1-1/2 feet high.

The front sight post looks like it can be turned, but it's square and appears to require a special tool. There's also a tiny little button or pin, that looks like it depresses and unlocks the front sight for adjusting.

So, how do I do this? Is the front sight post the normal elevation adjustment on these? Do I need a special tool? Where do I get one?

I'm sure I'll eventually put a scope or other optics on it, but for now I just need to dial in the sights it has.

Thanks!

<EDIT> just added some photos. I haven't taken any yet, these are from the seller. I'll put up some better ones after I shoot some with my camera. I hate blurry photos, but gun porn is gun porn.

You can definately get a special tool for the front sight to make it easier to adjust, but you can also use the tip of a bullet or a nail. We always had a nail to use when I would go qualify, but that was with standard sights. The Magpul back up sights don't have vertical adjustment on the rear sight, or at least if my set does I sure don't see it. The A2 type rear sight does have vertical adjustment but it's for after you zero the weapon with the front sight vertical adjustment.

You can buy a special tool for it but I use the tip of a 5.56/.223 round to get er done. Counter clock wise to bring it up some.

FMJ tip works.

Yeah, what they said, I just the small screw driver tip on my Multi-Tool.

Don't we have a AR zeroing guide around here somewhere?

OK, I did try that, and could depress the button with a bullet tip, but how do you turn the post? Tried doing that with the bullet, didn't want to move. I see in that video a brief photo of a tool, guess I can order it from them?

Small bit of oil on the front post and let it sit for awhile. Should loosen it up enough to not be a complete pain.
