I am looking to get an AR-15 DMR type rifle, and I'm hopping to get an idea of what other people have done, or would do.

What brand of AR-15?
Barrel length?
^Stainless steel or chrome lined?
Brake?
Bull barrel?
Optics?

Any thoughts appreciated.

I would get a LWRC M6A3 w/ 18" barrel. Either that or a KAC SR-15 Match.

$1800 retail (not counting ACOG), if you shop around you'll save some money. It's built around a WOA SS 1:7 20" SDMR barrel.

Build something around an 18" white oak barrel and a good trigger (geisselle or timney).

This (preferably Geissele) and a Young Manufacturing NM bolt carrier group = tack driver.

why white oak as opposed to a noveske, or something similar?

White Oak are great precision barrels. Like I said, I built mine off a WOA 20" 1:7 SDM-R barrel.

It kind of depends on what you plan to use it for. A military DMR (if I'm understanding this correctly; someone correct me if I'm wrong please) is made to be a rifle in a normal infantry squad/fireteam/etc that gives a little longer range. It is NOT a full precision rifle. It's used for man sized targets out to 600m or so (accurate, semi-auto fire organic to a group of infantry, just like a grenadier or MG).

In light of that, here's some rough suggestions for equipment:

Barrel: 18" or 20" 1:7 or 1:8 stainless steel. Should be fairly stiff/heavy profile, but probably not a full bull barrel. I like the WOA SDMR, as it has deep flutes that make it fairly lightweight with a heavy profile.
Trigger: Grab a good trigger. I'm using a Geiselle SSA-E, and am loving it. I can take slow, accurate shots, and I can also just slap through it for snap shots at closer ranges.
Stock: Something comfortable and repeatable. Whether that's a good collapsible stock with a cheek riser (say, a CTR with a Larue RISR), an A2 with a cheek rest, or a PRS. (I'm running a PRS)
Handguard: Go with what you'd like, but make sure it's a free float. I got my YHM Diamond for $125, and it's fairly light. Most people I know spend more on their rails than me, do what you want.
Bipod: You'll want something to rest the thing on. I've used Grippods, VLTOR Modpods, and Harris bipods on mine. My favorite is Larue's version of the Harris. They remove the chassis and replace it with a one piece chassis/QD mount. Ends up being light, low profile, and rock solid. It's $180, but you'd spend that much for a Harris + pod lock + good QD mount anyways. http://www.laruetactical.com/harris-bipod-9-13-lm-s-and-lt706-qd-swivel-mount-combo

As for optic, like I said....it depends entirely on what you want the rifle for. You looking at shooting steel man-sized targets out to 600y or so? Grab an ACOG. You want tighter groups/longer range? Get a magnified optic. In my case, my SDMR-inspired rifle was designed to complement my 20" AR10 precision rifle, so I went with a TA11F ACOG (3.5x with red chevron for better eye relief). The AR10 is getting a 20" Black Hole Weaponry polygonal rifled match grade barrel, same stock/trigger, Troy MRF308 13.8" rail, Kies adjustable gas block, and a Vortex Viper PST 6-24x50 FFP MRAD in a BOBRO precision scope mount.

Does that help?

Oh, and as corny as it may sound, Wikipedia is your friend in this case.

It's all you need for an SPR or whatever rifle. There are other options like Douglas 18" from Fulton, Bravocompanyusa 18", and Rainier Arms Ultra Match but they all perform about the same.

As far as other parts go that's up to you. Midwest, YHM, Troy they all work but the PRI and Daniel Defense are better overall. Just depends on what you want to spend.

Check these out. Guaranteed 1/2 MOA.

Also have a gander at their AR10 line. Decent guns. Of course you're paying more than if you were to build it, but you're also getting a pretty good guarantee. I have no personal experience with this seller, nor am I associated with them in any way. Just something I came across a while back.

If you want accuracy, do away the chrome lined. I prefer 16" LW50 stainless steel 1:8 twist heavy barrel with a good brake. If you want to tack drive it, get an 8x or 10x scope. LW50 is the next step up from 416R.

You can piece together a whole upper at rainier arms andd have them assemble it. A few members highly reviewed their ultra match barrels, but to save a few bucks, rainier themselves told that most shooters won't see the difference. Put it on one of their upper recievers, get a JP handguard, you'll stay below your budget.
