    Great barrel, used it for a varmint AR build first trip to the range I averaged under .750 moa. Barrel looks good functions well and shoots great. I would recommend this to someone else for a long range or varmint AR.

    I really like this barrel!! Looks great and the machine work is excellent. I got another 300fps out of this barrel compared to a 16″ barrel and it’s an excellent shooter. It’s a great barrel – Exactly what I wanted. (-:

    Got this build together. Long wait for the 24″ to come in but glad I waited. Had a problem with getting the right gas block sent to me but with e-mails and a few phone calls the right one came for my build. This is a heavy barrel and you can feel it right away when you pick up the rifle. This is for long range target so I don’t plan on packing it far. Dead on and love the look of this build. May have to do the same but with the Wylde Barrel next time. If weight is an issue for you this may not be the barrel for you. I don’t mind and it is just what I wanted. My buddy wants me to set him up one with the same barrel so looks like I will be doing this again.

    Decided one day to pick up a batch of consecutive serial number lowers and make a 5.56/223 heavy barrel collection of AR’s. All 5 were built with a 24″ 11degree crown. I purchased this barrel from a local dealer and added it to a upper of which nothing else is Anderson so cant talk to their other parts. Once assembled and broke in with traditional Marksman break-in of 100 rounds the guns were fitted with optics, to the range we go. All were shot with factory ammo of 40gr and 55gr ballistic tip boat tail ammo @ high velocity. Benched up @ 100 yards once sited in I could easily shoot 30 round mags with groups that could easily be covered with a dime. Once cleaned again and taken serious I shot 2 10 round groups that my 338 bullet would not fit through the hole. Since I have reloaded for this barrel and have got 100 yard groups that are around the 27 caliber diameter hole. P.S. This is by far the least pricy of the uppers/barrels I put together. This is also the most accurate of the bunch. I plan to buy plenty more for commemorative build outs for fellow sportsman groups.

    Heavy, shinny, accurate. Likes all ammo, 35gr – 77gr no issues. Great purchase.
    Keep them coming Anderson. Please create a Bulk buy program.

    4 stars only because I have not shot it yet, I’m in the middle of a build and was curious if anyone could tell me what the base diameter is so I know what barrel nut and hand guard I can order

    I waited till I got about 100 rounds through this barrel. I am not impressed at all sand bag front and rear so there is zero movement shooting off a concrete bench.2 -3 inch grouping and closer to 3 inch at 100 yards. I have tried 2 different scopes and mounts. I have emailed Anderson about this about a week ago and I have not heard back. Order number 138981 [email protected]

    Tim from Anderson sent postage paid shipping both ways on the original 24″ barrel. He also sent out a newer replacement barrel which Im very grateful. The newer barrel shoots a lot better and it still not even broke in yet. Thanks Anderson for the quick response and helping a customer I will be building another Ar soon and will be dealing with Anderson Manufacturing again. Thanks John McCann

    Hi I’m very interested in purchasing this barrel for varmint hunting. And would like to change my 16 inch barrel out for the 24 must you load single rounds or will this function in semi auto because of the longer barrel
    Thanks Chuck
