    Does this have M4 feed ramps? Will it run both super and sub without a suppressor, or is your carbine gas barrel a better choice? I’m looking for a barrel to mount on my Anderson upper I recently purchased. Thanks!

    • Tom Steffner

      Yes it has M4 feed ramps, you need an adjustable gas block to run super and sub. We think the pistol length performs better.

    Great barrel. Ran everything from hornady A-Max to the 245gr Missouri bullet cast rounds. Nice work

    I want to build a 300 blackout using this barrel. I see from posts that I should use the .750 gas block. Have read that I might need to use an adjustable gas block. Any thoughts??? PS I really like using Anderson Parts. Always fit, always work, always reasonable prices. Keep up the good work.

    built rifle with this pistol length gas port and an adjustable gas block. Fires both super- and sub-sonic ammo just fine with a standard BCG and buffer setup. Accuracy is right on.

    This barrel sucks! Best group achievable is 3″ from a rest at 50 yards. After burning 500 rounds trying to get this barrel to shoot I’m done. Contacted Anderson by email and after answering multiple questions I haven’t heard a word. Appearent their warranty is not worth a crap.

      Please let us know who you were dealing with.
      We have not had this issue before on the barrels.
      What was the order # so we can look it up?

    Awesome barrel. Can’t beat the quality at double the price. I see the same complaints on most mfgs. and most mfgs. don’t offer offer this price. You bought a great barrel at a cheap price. If someone isn’t happy with it, then something is wrong. Anderson will help. If its the barrel, they will resolve it. If its not, they will help you resolve the problem. Be patient and you will be satisfied. Don’t jump to conclusions unless you know your shit. This is a great buy so don’t screw it up for everyone.

    Purchased the 16″ Hbar barrel w the pistol gas system. Shot like a champ w a standard gas block, very happy w Anderson’s customer service. Was shooting 150 gr American eagle and loaded my own 147 gr projectiles using 296 powder.

    Exellent barrel at a great price point. My go to load is the Barnes 110 Tac-Tx bullet on top of H110, CCI 400 primer, Federal Mil case, COAL 2.250. This load hovers slightly over 1/2″ at 100 yards for five shot groups.

    • Michael Johnson

      Keep shooting

    ” you need an adjustable gas block to run super and sub. We think the pistol length performs better.”

    Do you think pistol length gas on a 16″ barrel still works better when attaching a suppressor?

    I’ve also heard that both super un-suppressed and subsonic suppressed loads can function without adjustable gas. Do you find this to be true? However, the AAC rep I talked to years ago also said that only 1680 powder works very well for the subsonic loads.

    • Michael Johnson

      we offer a carbine gas and pistol gas set up for the 16 inch 300 blackout. We have no issues with carbine length for 16”

      when it comes to the shorter lengths the pistol gas works better

    I want to build a 300 Blackout dissipator with a pistol length gas tube and an A2 sight at rifle length. What is the outside barrel diameter at the normal carbine or rifle gas port location?

    • Michael Johnson

      .750 is the diameter

    Just built a .300 blk using this barrel and mostly other Anderson manufacturing components and it is great. Took it out to break it in the other day and everything was great. Gun is extremely accurate and fun to shoot.

    I did a build with this .300 Blackout 16 inch, pistol length barrel and it went very smoothly. The quality is excellent and I am getting 3/4 inch groups with no feeding issues. Great product and a great price! Now if my tax stamp will come in I’ll be set…
