    Threaded? Not a rewiew, can’t find a comment or questions section for this, I would like to order this, but will Anderson thread it for me for an additional fee, or will I have to find an outsider to thread it for me?

    • sorry no Sir

    is the barrel treated with rf85?

    • Yes Sir

    This is an awesome upper. with a 6-18 power scope 500 yards is easy. it’s very accurate, and the fact that it weighs so much helps reduce what little recoil it has so you can watch your shot hit the target. The only thing that would have made it better is that I wish it was threaded so I could throw a suppressor on it.

    Since everyone else is asking questions here.
    Does this come assembled?.

    • yes it does

  5. 4 out of 5

    Will this work with a lower that does not have RF85 ? Does it still retain the quality of an RF85 Rifle or is it somewhat diminished ?

    • yes this upper will work just fine with a regular lower.

    i noticed in all the videos that there isn’t smoke blowing out of the ejection port like on most non-piston ar’s. does the RF85 have something to do with this? also you ever plan on a thinner 20′ barrel rf85 upper?

    • The RF85 does help keep things cooler when shooting since you have less friction.

  7. 5 out of 5

    Is there a sling swivel stud or a rail to mount a bipod?

    • There is holes to mount a rail on the bottom of the ext forearm.

  8. 4 out of 5

    Is the BCG treated with RF85?

    • Yes the BCG is treated along with upper, charging handle, barrel, and flash hider

    Hi a few questions. is the barrel floated? Your statement of “Gun-Barrel-Certified” is that for only what it is made of (IE “4150 Chrome Moly Steel with M4 barrel extension”) or is there some other meaning such as 1moa certified? When will this be available once more? Thank you

    • Yes it’s free floated, with proper break in and the correct ammo you should see 1″moa or better

    just a question, it says chambered in 556 nato/ .223, but looking at ammo 556 nato says it creates higher pressure than .223 and should not be used so which is this upper?

    • yes you should be fine

  14. 5 out of 5

    what is this upper chambered for 556 nato or .223 rem.

    • 5.56 nato

  15. 5 out of 5

    ON THIS 20 IN COULD IT BE OFFERED WITH TREADED BARREL AND THE AWESOME ANDERSON
    FLASH HIDER….I BOUGHT A 300 UPPER FOR FATHERS DAY PUT ON A REGULAR ANDERSON S
    LOWER MY 16 TEEN YEAR OLD GIRL LOVES THE NO CLEANING PART LOL

    • as of right now this barrel in not threaded

  16. 5 out of 5

    Can you make one with a 16 inch barrel?

  17. 5 out of 5

    This is not a review. Is this California compliant? or will i have to get it threaded for muzzle break?

    • This is a complete Upper receiver, yes it’s CA compliant because it’s not considered a weapon. Please refer to your state laws before placing on a lower receiver. Anderson Manufacturing does not give legal advice. Thank you

    Love how accurate it is and the weight isn’t bad, but the extended hand guard only has picatiny rail on top…..can I buy the rail and screws from Anderson so i can mount other stuff? The screw holes are smaller than normal rail screws

  19. 3 out of 5

    Is the price correct ?
    $805 Is a whole lot of money for just a complete rf-85 upper as described.

    • Yes the price is correct.
      we will take a look at this and see if something was miscalculated

    I have owned this upper for a few months now and absolutely love it. As stated by Tom, it shoots better than 1 MOA. With a 62 grain M855 bullet, I have rounds penetrating the same hole at 100, a dime at 200, and within a quarter at 300m. Obviously, this is a BULL barrel guys!!! If you want a threaded barrel, look at the dozen others on the site. BTW, You can buy screws and an EXT rail to mount along the other sides of the forearm/handguards to answer a previous question. The weight of this barrel is exceptional for precision shooting-just make sure you have a bipod and the necessary hardware. I have aTrijicon Accupoint scope to match it nicely also. This barrel deserves something twice the price after all.
