    Kinda feel like I'm coming out as a homo here, I've been making fun of these "machine-guns" for years, but I think I might enjoy one of these, in a bigger caliber. I'm told a .308 is called an AR-10, but I have no idea. I just wanna know if it's cheaper to buy one, (are they quality?), or build one (I get pretty particular, don't wanna break the bank.) I do want a bigger caliber, so don't mention a .223/5.56 whatever. I'd like a longer barrel with it, don't know how long they go. Anyway, I hope I didn't hurt any tender feelers here, I just find myself in an odd place here. I'm a hunter, not "tacticool". I've never played MW3, I don't even own an Xbox. So I'm not that guy or anything. Just ignorant.

    dont feel silly its fine. you are correct. the term ar 10 is equal to a .308 ar. same as with the smaller caliber though you will find differrent names for different companys. its a popular setup especially for hunters. most of the time they have a 22 or 24 inch barrel. i would assume its cheaper to build one. they are pretty much the same as a .223 just everything is larger in scale. i have not shot one. but may purchase one in the future. if you plan to buy one i think they start around 1300 for decent quality.

    here are a couple photos showing size difference.. ar 10 /ar 15

    Dpms and armalite are probably the top two in the AR-10 platforms that I know of. As for building one, good luck. With those two being the main two, it's hard to build one with no mil spec. I know the dpms is about 1200 with a heavy bull barrel. You said not to mention the 223/556 but you can buy a 223 lower and look into the 300 blackout by AAC. It's a 30 cal that can fit into a 223 lower. I believe it's a 7.62x35

    You are correct, a .308 would be an AR-10, not so much for caliber but because of the case length, 51mm I believe. An AR-15 maxes out at about 45mm. Some larger calibers like 7.62x39, .458 SOCOM and .50 Beowulf are available for the AR-15 platform.

    As the prior post stated, everything about the AR-10 is a bit bigger and a bit more expensive, starting with the lower. A run of the mill forged AR-15 lower can be found for $50 on sale at any of a dozen vendor sites, AR-10 lowers start at about $200. One other thing to keep in mind is that whereas all AR-15 parts are pretty much interchangeable, AR-10 parts must match either the DPMS or Armalite pattern.

    Anyways, welcome to the addictive hobby of AR building...check out the various post found throughout the forum.

    dont-dont be saying that around here too much. i do agree with you, but apparently if you say DPMS is good, the holier than thou AR lovers come out of the wood work and start mentioning companies youve never heard of that are better, but if youve never heard of them how do you know their good?

    sorry to get off track, never found anyone give props to DPMS like i do, but i second Shag's opinion. To back it up the NRA's rifle of the year in...2007? i think 2007, was the DPMS LR-10.

    Yeah I've heard of bushmaster making one but I am not a fan of bushmaster at all. That and I was looking into getting a dpms LR-308 in the near future. I had forgotten one brand actually and I apologize for it, Rock River Arms makes one as well. Never played with one but heard good things as well

    If you’re looking at an AR that would run a few thousand, you may save some money if you build it yourself. If you’re ok with something more reasonable, you won’t be saving that much by building yourself. At least that’s what I decided when I looked into it a while ago. Also be careful about the parts, apparently.308 parts aren’t all interchangeable like the .223s.

    Are you a BIG guy? I gotta say the Rock River & DPMS .308s I hefted are HEAVY. Really, the AR10s make the AR15s look like a Mattel toys. They’re not something I could see myself schlepping through the woods, but then I don’t hunt anyway.

    I'm big enough that packing guns all day doesn't bother me, but I have bolt guns for hunting. This is mostly a look what I have, try and hit things a long ways away gun.

    A .308 will definitely do it

    Left is ArmaLite AR10, right is LWRCI M6A2 (AR15). The AR15 weighs about 8lbs, unloaded with optics. The AR10 just over 11lbs, unloaded with optics.

    Just to give you a general reference.

    When compared to humping in to a stand with a 6-7 lb bolt action rifle, you definitely notice the AR10's extra weight. It is manageable though.

    I really like my DPMS LR308. Not frilly, not dust cover or forward assist, but goes bank and hits where I tell it to. I like the thought of a heavier round and energy from the .308 over the 5.56. If I didn't have all the ammo stocked for my AR15 I would probably get rid of it.

    You might want to look into the other calibers offered on the AR-15 platform.....and there are many. Your choice depends on what you plan on using the firearm for.

    For example, the 6.8 SPC - about 80% of the ballistic performance of the .308, deadly on deer out to 300 yards, etc.

    Treehugger beat me out on the 6.8 spc option. There are some very nice uppers out there that drop onto standard ar15 lowers. If you find a good deal on a full ar15 and then pick up a 6.8 upper you basically get 2 guns.

    POF are piston...and considerably more expensive. And as you say, good luck on the wait. After three months waiting, I stepped up a little more and went with LWRCI instead. They are a low profile gas system...same profile as a DI gun. You might consider them.

    A lot of guys like to build off of the MaTen receiver sets from Mega. They are nice but not to expensive.

    Rainier Arms sells barrels and of course Noveske make awesome barrels.

    I wouldn't touch a DPMS anything.

    Mj, why the neg on the DPMS? Are you referring to the 308 upper or the gun as a whole? I'm not a big DPMS fan at all but I'm just curious. I have a older, maybe mid-80's DPMS A2 20 inch bull that I free floated with a Leopold 3-9x on top of the handle and I'm sure I did other mods to it at the time and every now and then I'll pull it out just because and I've never had a serious complaint. Not what I'd use for a new build but not something I ever had an issue with it. Pretty damn accurate with standard ammo. Again, not knocking your opinion, just curious.
