whats a decent price for a .308 AR-15.

They seen to be going for 1100-1300 for DPMS and Bushmaster Have seen some DPMS for 1000 Only place I have seen any is on GB I have been after one for several months. And GB is the only place The other AR 's are going for 1400+
 
wal-mart has dpms lr 308 rifles for around 900.00 . I have a rock river 308 and it is a tack driver just be prepared to buy fn-fal magazines or rock rivers own polymer mags.
 
The .308 AR platform isn't standardized like the AR15 is, so you're looking at a range of rifles that are similar in design but partially or completely incompatible in their parts. So your ability to upgrade later is more limited, and you're basically buying a proprietary design that may have limited parts options, instead of a military-based design with dozens or 100's of parts options.

For $1k or less you're looking at the DPMS and not much else. It's actually a pretty good rifle as long as you don't expect "mil spec" type details (barrel steel, testing, etc.). Compare it to other semiautos that aren't derived from a military design and it's a good rifle and relatively modular.

Step up the price a little and you have options from Armalite, RRA, and S&W, with S&W being the newest by far. It may also be the best quality wise but that isn't proven yet. If you want to shoot tiny groups at a bench, DPMS and RRA have better affordable free floated options.

Go up towards $2200+ and you get some additional nice options like the Colt 901, LMT MWS, and Larue 7.62 rifles. I'm guessing this is outside of what you want to spend.
 
I have the Smith and Wesson M&P10 (308) and a Black Rain Ordinance 308. For the $ the smith is one great rifle. I have the smith set up as a mid range and the BRO set up as the long range. I have a feeling that the smith might actually be more accurate. I only have a 1-4 power on it and a 4-16 on the bro. I might swap the optics and see what one shoots better groups at 300 yards.
My vote for the price range is the M&P10.
 
I like the Armalite AR10A (the one that takes PMags) if it's my first rifle. Will run about $1300. Armalite uppers and lowers are high quality, 7075 Forged Aluminum. This rifle can always be upgraded later one part at a time. Aramalite upper to lower fit is super tight and there is no better combo of upper and lower out there.

The Armalite AR10B was my first 308-AR. All the parts of that original rifle is now replaced except the
1) upper
2) lower
3) BCG-group
4) buffer tube and spring
5) gas block
6) LPK minus the trigger.
7) 2 magazines

Keep in mind, these 7 parts will run you about $1000 alone, so that extra $300 you pay for a complete rifle to play with while you "build it up" will be quite a bargain!

Remington actually made a rifle in 30 Remington that is the size of a AR-15. DPMS made the rifle with Remington's name on it. It would launch the 308 caliber bullets in the 125 grain range around 2800 FPS. Getting kind of hard to find.
 
I've had the DPMS LR308(I think that was the model?) with a 20 or 24" bull barrel. It shot just under an inch (.9'ish) with factory ammo. If you get a DPMS, start saving for an aftermarket trigger. I think I had the JP Ent trigger in it, and that's when I got the groups under an inch. I don't know that you can get the rifle for under $1000 right now though. That's what I would look at in that price range. But if you could bump it up a little, the Armalite would likely be a better option. I've never had one of those, but hear good things.

Centerfire Ammunition - Rifle Ammunition - 30 Remington AR

Yeah, it basically flopped. The performance was only marginally more than a 6.5 Grendel or 6.8 SPC load, especially if you used apples to apples barrel lengths (the 30 Rem AR was based on a 24" barrel, while most 6.8 SPC ballistics you see are measured in a 16" barrel). But the case is super fat and loaded into magazines in a single stack, so very little magazine capacity, and of course it's hard to find the ammo since only Remington made it. You don't want one.
 
I think you could build one yourself for around $1200. I just built one using a Mega MATEN billet upper/lower, DPMS SASS .308 barrel and DPMS .308 complete BCG for $1,011 (just added up the receipts). Again, if you're not in a hurry, I think you could build it yourself for $1200 (including the LPK, stock, etc.).
