...if the group buy doesn't work out I'm going to be looking for a barrel. Specifically a 16" midlength, no-ban config., 4150 steel, 1:9 twist, and preferably something that is not HBar, but not pencil thin either. Are the RRA barrels listed at ADCO 4150 steel or 4140?

Who else carries barrels in this conficguration?

ETA: 4150 is the lowest requirement on the list, but if I can get it I will.

ETA#2: I'd also like to know if the ADCO barrels are chambered for 5.56. Thanks!

Adco sells Rock River Arms barrels. They are 1/9 twist, 4140 steel, available with or without chrome lining and they are not .223 chambered. I can't remember if they are a true 5.56mm or if they have the hybrid Wylde chamber but I know they'll work just fine with 5.56mm.

Thanks, I didn't really think the steel mattered that much, I just figured if I could get 4150 I would, but 4140 is just fine.

Those are the ones I think I was looking at on your website. I think I also saw your EE ad. I may be placing an order with you soon in the group buy doesn't get off the ground by the end of the month!

I don't think you'll regret it...



And I was told when I bought it that is has a true 5.56mm chamber? That's one of the two main downsides to it, no 1/7 twist and no barrel markings but neither are really major issues when you get down to it. 4150 steel would be nice too but again, not a deal breaker.

RRA and Armalite are about it for regular production barrels.
