So I can vicariously live through those of you that aren't broke college students.

Here's another newbie question, what's the pros/cons of the stainless barrels? I saw that as well a little earlier, seemed like a pretty good deal.

The type of steel is far less important than the dimensional quality of the barrel and the care the barrelmaker took to stress-relieve the barrel.
You will hear all of sorts of anecdotal stories about stainless steel lasting less than chrome-plated chrome moly steel and about the tremedous superiority of 4150 steel alloy over 4140.
The reality is this. A barrel "dies" when its throat is so eroded that it starts ripping at the bullet jacket enough to reduce the accuracy unfit for your needs. You have to decide how much accuracy loss you can endure before the rifle isn't suitable for your uses. While stainless steel used in barrels (typically alloy 416) is not as resistant to flame cutting as bare 4140 or 4150, it will still go at least 10K rounds before the accuracy declines to where it won't meet military acceptance standards (4 MOA IIRC). In precision uses, like NRA Highpower, a stainless barrel is shot out at around 3500 to 5000 rounds, but you are talking about a barrel that won't hold 1 MOA at 600 yards. Such a barrel still has tons of life left in it for other uses. So "shot out" is a moving target and it depends on the purpose of the rifle.
The hard chrome plating in some barrels' bores and chambers does extend life by virtute of its higher hardness and resistance to flame erosion (important in the throat) coupled with chromes high oxidation (corrosion) resistance.
As for having to have 4150 chrome vanadium steel in your barrel instead of the more common 4140 chrome molybdenum alloy, it matters if you are going to be doing a lot of full auto or just want to pretend you are cool because you have a "milspec" barrel.
Otherwise, it makes not one hill of beans of difference.

Is there a board member currently putting together ARs for purchase?

How accurate can you expect to shoot with a base AR with iron sites standing at 25 yards?

Puryear, Bender, txyaloo, tx4guns and anyone else that builds a ton of ARs - picking up parts for my .300 blackout SBR build and looking for a premium barrel. I'm a buy once/cry once (within reason), but Satern/Liberty don't seem to have 300 blackout SBR barrels in 8-9 inch, which is the length I want.
Saw another thread where the AAC and Noveske barrels were getting a ton of love. Found this 8.5 inch noveske barrel, but it comes with a low profile gas block. Noveske 8.5 inch w gas block
I was going to go with an adjustable gas block on the rifle so I can tune it if needed, as I'll shoot supers and subs, both with and without my suppressor. Can I remove the stock Noveske gas block that comes with this barrel and replace w an adjustable bas block if I need to? Will start out shooting factory ammo, as I have zero time for reloading.
Other recommendations on premium 300BO SBR barrels?
Thanks, I'll hang up and listen.
I think you may have just violated California law by posting on this thread.BenderRodriguez said:kberma2009 said:

You can build one, we can help.
I'm in California for a week so my responses are going to be limited to what I can type in a phone for now.
I helped my MIL's boyfriend build one with an Odin Works barrel that came with an adjustable gas block, and he has been very happy with its performance.dr_boogs said:Bump for the morning crowd.dr_boogs said:

Thanks everyone for the feedback. Putting a Wilson Combat on my 6.8 SPC thanks to a barrel swap from EyeGuy. I checked Wilson as well for the 300 blk barrels for SBRs and couldn't find an 8-9 inch. Ranier was a good thought, forgot to mention them in my thread. All of their entry, mid-level, and premium barrels in 300 blk are listed as out of stock on their website. Found a decent price on the 9 inch AAC barrel, so may go with that one.35chililights said:
I'm happy with my Wilson combat barrel. I could have sworn they made a smaller size than turbine I have at 11.3", but I can't seem to find it.
I think you'd be happy with any of the barrels. You might check out rainier arms. That was one place I was searching before I settled on the Wilson barrel.
