30-06 was available. I believe Bushmaster bought the company that was making them. There's no reason you can't, just not much market I'm guessing. Magazines might be a bitch for anything past 10 rounds.

My guess is mainly interest. It get's cost prohibitive to shoot magnum calibers. Outside of people on this site, I don't know a lot of people buying AR10 variants for the same reason.

Yeah but hell, look at the guys spending big bucks for the .338 bolt actions then another $2000 to accurize and customize. At the end of the day all you're left with is a bolt action rifle. Then to shoot them you still send at least a Washington downrange everytime you pull the trigger, even if you're reloading. If I had the option of a quick follow up without operating a bolt I would damn sure take it. If you're getting all paranoid worrying about slinging brass and giving up your super secret squirrel sniper hide, give the upper a side charge handle and toggle off the gas port with a little valve. |

Cobb made a 30-06. The .308 platforms can also shoot a .338, .243, and .260 Remington. I'm holding out to actually see some data on the .30 AR because it is supposed to get .308 performance out of a .223 sized reciever.

Too much $ for the rifle IMO. I reload for my .338lm and still cringe at the thought of funding ammo for a semi in that caliber.
.338 Lapua Magnum AR Only 13lbs!  . Probably upwards of 17-19lbs one you put everything on it... If money were no object I would have one of these. Suppress the thing or get a good break and you could really do some serious damage with that thing.

Take something like that but for .270/.280/.30-06/.300 Win and work to bring it in at a price point somewhere around $1200. The biggest pain in the ass is going to be getting barrels made. |

This is a a little off your topic. With your example of 338lm, the round's main advantages are long range and accuracy. I'd rather have a bolt action rifle firing it for the accuracy advantage over a semi (even if only perceived) because too quick/ too many follow up shots negates the 338's advantage. I'm also a self admitted cheap skate who rarely even fires a full 30 round mag of 223. I'd never be able to enjoy rapid firing a 338 even if I had millions in the bank. |

Couple years back, somebody was making a lower with interchangeable mag wells for different length magazines. Attach the correct magwell for your chosen magazine and caliber, then attach upper, then you're GTG.

Why would you be interested in a .30-06 when .308 is only a couple hundred fps slower? It's not like .30-06 blows away the .308 in terms of performance. |

Above the 308/3006 range rounds, mag fed semi-auto goes out the window with belted rounds.
Besides at that point we are looking at a 15lb rifle, which is pushing it on the weight even by precision rifle standards. That said, a 33 lupa should be doable and I think work the effort. |

I don't think .30-06 beats .308 by a few hundred fps. I think the .308, being shortened and improved, is probably pretty close to being a ballistic equal to the 06. As for belted cartridges not working in a magazine, why wouldn't they? There have been magazine fed rifles chambered for belted cartridges since 1912 or so.

And likewise how the modern .308 has about the same performance as the .30-06 of old because of modern propellents. You can ALSO upgrade the performance of the .30-06 into the magnum realm using modern propellants also, because it has a bigger powder capacity than .308 It's not a one way street where you can only improve the performance of .308 with modern propellants and you can't do the same with .30-06 |
