1:8 twist options
I'm looking to put a new barrel on my AR and really want a 1:8 twist.
So far, I've only found two options: Faxon Firearms AR barrel or Sionics Weapon Systems.
The Faxon barrel is Nitride/QPQ finished, which I know little about, but can be had for $180 shipped at Aimsurplus.com http://faxonfirearms.com/16-govt-soc...ngth-4150-qpq/
The Sionics barrel is chrome lined, but is $249 plus shipping http://sionicsweaponsystems.com/stor...gas-block.html
The barrel would be used on my hunting rig and I would want sub MOA groups with my Sierra 65 GK hand loads. Of course, smaller groups would be awesome.
Am I over looking any other barrels?

Haven't used them personally but faxon should be GTG. Another option would be Black Hole Weaponry. They can make the barrel to your exact specs. A 1/8 should get you those results from what I've seem but I can't say first hand.

Lilja has the M4 Patrolman in 1/8 but it's a carbine gas. It's been a great bbl though on the heavy side. On the good side it's got a 223 Wylde chamber so you can shoot 5.56 pressure ammo.

Rainier's Medcon bbls are very nice. I used this one in my most recent build though I haven't tested it for accuracy yet. It's 1/8 with polygonal rifling. Actually I believe Rainier offers several bbl options in 1/8.

1:8 tends to be more popular with .223 Wylde chambered match barrels.
Most of the Ballistic Advantage Premium series are 1:8 - check out their Hanson line: http://ballisticadvantage.com/shop/b..._twist_rate=32
Also consider AR Performance: http://www.ar15performance.com/barrels
ARP is primarily known within the 6.8SPC community. My 16" ARP 6.8 SCOUT will shoot sub-MOA at 100 yards with factory Federal XM68GD.

If you don't want stainless then, yes, you are pretty limited. The AR Performance barrel is what I use for hunting, so I have no qualms recommending his barrels.
One other option is Criterion. I don't have first hand experience with Criterion Barrels, but they have an excellent reputation: http://www.brownells.com/rifle-parts...prod54733.aspx
I prefer nitride/melonite over chrome lined, though. Superior barrel life and potential for SS accuracy.
All that said, I'd think you'd be perfectly fine with 1:7 if you are shooting that heavy of a bullet.

Ahh. Ok. Brownells has AR stuff on sale still.

Tons of options in 1:8.....just look around a little more. Rainer (Select, Match and Ultramatch), Lilja, Ballistic Advantage, Faxon, ARP have already been mentioned. I'll add Odin Works, Northtech Defense, Wilson Combat, Battle Arms Development, BCM, Mega, Seekins, Proof Research, Satern (for Brownells), Green Mountain, Spikes Lothar/Walther, Anderson, AR Stoner, WMD.
I'm a huge fan of this twist even though I'm seldom shooting 200+ yard distances where the difference between 1:8 and 1:7 becomes more meaningful.

The probability of you shooing out a stainless barrel on a hunting rig is next to zero.
The volume is generally modest to start with and the low rate of fire plays to longer life. Unless your hand loads run at dangerous pressures, I suspect a good stainless barrel would outlast your ability to use it in this duty.
