    Does this barrel actually need a gas block? Every other 9mm AR barrel I’ve seen doesn’t need one

    • Tim Poteet

      Hello Tim, no this barrel does not have holes for a gas block.

    The barrel came with no threads…. Now I see it on the pic but wish it wouldve had it in the description I would have paid more for factory threading….

    Barrell feels heavy and good quality I like that part..

    Glock mag compatible?

    • Michael Johnson

      this is just the barrel.
      the lower is what you will need to check to see if it can hold the Glock magazine.

    Is the description on this barrel correct? I am very interested in this but from the other questions I can’t be sure it fits my needs. Threaded barrel? Carbine gas system? Thank you for your time.

    this is a very nice barrel, finding the rest of the components for a 9mm AR, NOT so MUCH. Still can NOT get a flash suppressor, BCG, or the 9mm buffer extension to complete.
    3 Stars only because of lack of support for the above items.

    • Michael Johnson

      we are in the works with our 9mm as we speak.
      please keep in touch and look for this in the future

    I bought this barrel earlier this year when I built an AR-9. WOW! What a joy this thing is to shoot. The barrel went together perfectly, and is extremely accurate. Thank you for a great product at a great price.

    psa has everything you need 9mm lower ,bcg, mags,breaks, complete lowers for colt mags or glock. I really like the punisher lower. I have built three.Now for the punisher upper,then a RF85 upper, lower,bcg and barrel in 6.5 grendal.
    Now that my friends will be Fun. NO LUBE wow no more HOPPES #9 or BREAK FREE CLP.
    I can wait for it all to be in stock. Do not have a choice.When that grendel is back in stock i will get the RF85 upper and lower and the parts kit. Then 224 V. Thanks Anderson for your great parts. The Gun Factory,Unlimited
