    I have this barrel on my AM-15 upper/lower from Anderson and it fits perfect. No problem reaching out 300 yards so far. It’s a little heavy, but seems to be very durable. 300 rounds 5.56 55gr Winchester and zero buildup in barrel. You will be very happy with this.

    Received my barrel. You stated that rf85 parts are marked rf85 my upper receiver is marked rf85 the only marking on the barrel is AM.
    Just wondering

    Bought the complete upper 5.56 16″ 1:8 twist mil spec barrel. What follows is to all but addresses the jbgardner review, from July 7th 2015, take note. My barrel is marked with, 5.56 NATO 1:8 twist. The lit. states all metal parts on RF85 guns, are treated with RF85, as I understand. The only places marked with this are,…the Upper and Lower with both on the left side just behind the bolt hold back/release paddle. Had I know about them before I started my build I would have just bought the fully completed rifle, still,.. building one with all their parts gave me great insight into the function and taught me how to repair, should it be needed. Note: As you should be able to tell by now, I am not with Anderson but a happy customer that’s glade I found this company before I got started building the upper portion of my rifle build. Also note at shot show 2015, Mr. Anderson said and someone correct me If I’m wrong, the Bolt carrier group runs with 93% less friction and the barrel runs twice as lone as a standard chrome lined mil spec barrel as well as something about it lasting for about 14,000 rounds. He also said, to my understanding, they are the largest manufacture of Lowers in the United States. I believe that includes RF85 treated and the regular lowers, full and 80% finished, so,…. Yah,… Five Stars! count them *****

    I purchased this RF85 barrel for the RF85 upper receiver I purchased earlier. I purchased them separately for funding reasons and assembled my own RF85 complete upper using Anderson’s handguard, gas tube, block and flash hider. As I stated in an earlier review of the RF85 upper receiver; if you’re still running a ‘wet’ gun… you’re livin’ in the stone age! 🙂

    Do you have AR-15 5.56 RF85 in 18in?

    • No Sir 5.56

    Would it hurt the barrel if I oiled it and cleaned it with say Remington Oil? I would use a dry rag afterwards to leave a light coating.

    • No Sir it will not hurt the treatment

  8. 5 out of 5

    Is this barrel any less accurate than a normal barrel. And what is the lifespan of this barrel? Thanks.

    • Non RF85 treated barrels last 7-8k thousand rounds, RF85 treated barrel last 13-14K thousand rounds. These barrels are just as accurate non treated barrels

    More of a question than a review: On this barrel set for a carbine length gas system, Can you run a mid length gas tube with the same 0.750 gas block to lower your recoil with the aid of a heavier buffer?

    • No Sir

    Awesome product super fast shipping, ordered a bcm handrail from another company with 2 day air shipping the same day and time and my upper receiver and this barrel came before my handrail thanks guys at Anderson. I will be doing more business with Anderson manufacturing. I also have a Aramalite rifle it’s nice but I wish I would of knew about Anderson sooner I prolly would of bought one of these rifles instead can’t beat the price and quality of these guys. Thanks again

    • Great to hear about the shipping.
