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.
