    Decent barrel. Would have preferred a Grendel II chamber.

  2. Rated 5 out of 5


    Great Barrel for the price. I usually use much more expensive Grendel Barrels and thought I would give one of these a shot. Built it up and off to the range. Sighted on 3rd round and on target. This will make a great Med Game Rifle at a very reasonable price. Ill order more as soon as they are back in stock.

    Impressive. I bought this barrel to build a lightweight rifle for hunting, I was previously using my 20″ heavy barrel 6.5 Grendel and it was too heavy and awkward to enjoy carrying through the woods. Much to my chagrin, this $100 barrel shoots exactly like my expensive competition barrel.

    I ran it through an abusive break in with no lube, and had no failures. (I bought the bolt carrier group from here also). When the barrel heated up after 24 rounds, there was less deviation than my fluted stainless steel heavy 20″. It groups wolf military special better than my other one, and shoots sub MOA with match.

    I highly recommend this barrel, I hope that you all keep making it, I might wear this one out…I would really like to see it in RF85.

    • Michael Johnson

      We are glad the product is working for you.
      please be on the lookout for this in RF85 in a few weeks.

    What magazine does it use?

  14. Rated 5 out of 5


    Are you sure this is type 1 Grendel? My bolt head (from Anderson and ordered in the same order) measures 0.136″ deep in the case head recess. Type 1 from everything I read is 0.125″ (same depth as a .223 bolt recess). I can chamber a round and it’s tight with your 0.136″ case head recess bolt which I believe means that this and your bolt are both Type 2 Grendel.

  15. Rated 5 out of 5


    Here’s where you’re getting confused: Grendel I and II have to do with different iterations of the chamber. There was a minor adjustment in the THROAT. However type 1 and type 2 bolts are a while different topic and hark back to the earliest adaptations of 7.62×39 to ARs. The less common .135 bolt face got called type 2. So in this barrel it is a Grendel 1 chamber which were required to use the. 135 (type 2) bolt under the trademark. Even now that the trademark has been released, .135 is the standard. Manufacturers would be pretty foolish deviate from that and not make it VERY clear. The safest solution is to buy bolt and barrel from the same manufacturer which it seems you have done.

    I bought this 16 in barrel and Anderson bolt together. I wasn’t sure about type 1 or 2 with these. I’ve shot 123, 120, 85gr, and some wolf steel case with 100 gr bullets. All shot flawless. No jams in any.
    My other Grendel is a 20 inch type 2 and cost 3 times more.

    I have one works great once broke in my chamber was a little tight using either type 1 or 2 bolt faces I polished the chamber a little feeds good now. People are getting confused on the type 1 and 2 chamber thing their bolt faces are actually a type 2 spec but the barrel chambers are type 1 which means you can use either type 1 (.125) “7.62×39) or 2 (.136) bolts.

    I ordered this bbl. A couple weeks ago along with b.c.g. was shipped same day, within hrs. of order, I got it next day, I live in state next door. Fit and finish is superb and headspace is good! Haven’t fired yet, so no accuracy results to report. This bbl. Wasn’t in stock when I decided to buy it either, but i checked on it frequently and it became available in a couple short weeks. Some folks shouldn’t blame others/anderson for their own lack of diligence, just saying!

    I find it odd I post a negative review to see it deleted. I purchased two of these barrels to go with Anderson’s associated BCG. Neither one would chamber factory rounds. On further review with a bore scope and a Grendel reamer which is in spec there is definite proof the reamer used to run some of these barrels was out of spec and have pictures to show it. Generally this is associated with a reamer being sharpened one too many times. I’m not sure who makes these barrels for Anderson ( I’m almost positive they do not make their own) but they are definitely an epic fail. Like many manufacturers in the industry quality control is going by the way side and it is an utter disappointment as I have had no issues with Anderson prior. Come on guys regardless of the fact that I have a grendel reamer I didn’t buy a drop in to have to fix it.

    • Michael Johnson

      what was the order number for the barrels and BCG?
      We would like to discuss further to see what the real issue is.

    Picked up the barrel about a month or 2 ago. I ordered a .136 bolt that I installed on a FA rated BCG and I have had zero issues. 6.5Grendel is .136 bolt I wish they would stop this type I or II junk. They should say SAAMI chamber instead that’s less confusing. If you use .125 it’s on a 7.62×39 or 264 LBC Thanks for the deal on the barrel Anderson mine runs lacquered steel and brass just fine.

    Great looking barrel out of the box. It is roll marked “1/8 6.5 Grendel” (I add that since it was circulating on some website that the barrel had no markings on it). Rifling looks great. My questions are, 1) it says that it is Grendel 1 chamber…is this the SAAMI spec chamber, or another chambering for the Grendel? And 2) what is the barrel steel? Some Anderson barrels are listed as 4150 or 4140, but this particular barrel is not designated as either.

    • Michael Johnson

      The steel is 4150 on the barrel

    Can we get an accurate picture, please?! My only issues so far with Anderson Mfg. is mostly because of the lack of good pictures for your parts, and consistent information in the descriptions across all the part types.

    I was given this barrel as a Christmas present. I installed in onto my Anderson upper and used the matching bolt carrier group from Anderson. My lower is also a Anderson. The gun looked great but would not function. My head spacing was to tight. I contacted Anderson and they swapped out my barrel for a new one. The new barrel works great. I’m still giving them a 5 star rating because of the service I received and the speed that they responded. Special thanks to Tim for all the help

    Just got back from range. My grendel build is sub moa at 50 and 100 yds using a vortex strike eagle scope and Hornady a max 123gr. Chambered rounds perfectly, no malfunctions. Anderson parts are awesome. One thing I noted was when I chambered a round and then removed it unfired, there was a small dimple on primer. Is that normal?

    I love this barrel. I used an Anderson upper and lower along with it and my friends with their 24″ $450 barrels stay ticked off at me when I routinely outshoot them. Really, 40 rounds through a one inch hole at 200 yards. I live to see their tears. Really does a fine job filling the freezer at deer season too. 3 does ranging from 85 to 190 yards. None went farther than 40 yards.
