[Big 3 East] Wolf Ammo Is Bringing Us A Type 91 Upper

Wolf Performance Ammunition is bringing in Type 91 uppers and completing them with US made barrels. The Type 91 is the standard issue service rifle for the Taiwanese Army. It is gas piston operated but lacks a forward assist and brass deflector.

According to Steve of Wolf Ammo, the upper will retail for $599 with a carry handle rear sight. They are calling it the WolfA1. I think it should be called the Wolf91 since it is a Type 91.

Notice the lack of side serrations because there is no forward assist.

The gas piston is easily removable with a half twist of the retaining bolt in the side of the gas block.



I got to test fire the WolfA1 upper and while it works well, I was curious if it is full auto capable. Steve did not know if it was, so I asked Palmetto State (who were next to us on the shooting line) if they had a full auto lower. They did and were kind enough to lend it to us to test the Wolf A1. It is full auto capable. I like being able to assist in the testing if something is full auto or not. It is for science yes, science.



Besides the Type 91 upper, Wolf is making a 6.5 Grendel upper and it will retail for $400. Yes it is full auto compatible as well. Although it is not as fun as shooting the Type 91 upper.

Wolf is also going to sell .300 BLK primed cases and they should cost around $0.16 per casing. They have successfully been able to sell 6.5 Grendel as low as $6 a box. And they are going to be bringing in a .303 British round that is a bimetal copper/steel cased.

I am looking forward to the Type 91 as I want to make a semi auto replica of the Taiwanese issued service rifle.

  • john huscio

    Looks amazing

  • TM

    Wooo! .303!!!

    • John


      If this fires actually fires .303 British, then Wolf should IMMEDIATELY enter this into India’s rifle tender. Seriously.

      • Henry Servatt

        I don’t think this meant the rifle does .303 B, just that Wolf is bringing in reasonably price .303 ammo. I could be wrong, tho, so don’t take my word.

  • William Johnson

    Looks interesting, if it proves popular someone with a CNC will add rail or m-lok compatible handguards.

    If they bring in cheap .303, my Enfield may get a range day.

    • Twilight sparkle

      People don’t tend to buy uppers like this to change the hand guards like that.

  • thedonn007

    It is too bad the recoil system is not self contained in the upper. It would allow for a folding stock on an AR-15 lower. I am interested in the 6.5 Grendel upper and $0.30 per round 6.5 Grendel ammo.

    • Joshua

      The ZM LR-300 was like that.

      • noob

        hmm i remember that there was a little c clip in the ZM which if you lost it in the dirt, you’d need to replace it before you can reassemble it.

    • BrandonAKsALot

      I’m considering buying one of these for this exact purpose. The carrier should be able to be cut down and have a spring jammed in there somewhere. Just have to figure out where.

      • thedonn007

        Yea, I don’t think it is going to work like that.

        • roguetechie

          Well… Ummm… Yeah it kinda works almost exactly like that.

          There’s M231 which has a butt cap that has a polyurethane buffer that’s donut shaped to make space for the guide rod down the center and the 3 nested springs each having reversed coil direction to prevent binding, a striker that can actuate the firing pin on bolt lockup, buffer tube surrounding and containing these parts when gun is “cocked”, an altered bolt carrier especially the rear half which must allow the striker free access to firing pin.

          There’s also the very interesting fcg that makes the 231 open bolt full auto only.

        • BrandonAKsALot

          It’s been done. A lot.

        • DeathFromTheShadows

          I suggest you look at the Remington line that started with the Model 740… and contains the 742, 7400 and so on. and lets not forget the Mini14, Mini30, and naturally the Garand, the M1 Carbine, and a whole slew of WWII era gas operated rifles and then there is the SKS and the AKs

      • roguetechie


        That will get you a very short buffer tube at best, yes I’m sure DPMS carbon 15 and several others have done exactly this.

        Please don’t molesticate a cool and coveted item to duplicate what you can buy in a huge variety of configuration and fit outs for about the price of this upper.

        Now if you want full buffer less a la extar exp556 Sig mcx para ttr zm-300 and multiple other designs that are commercially available, It’s totally possible to convert it any number of ways.

    • Just say’n

      Classic Arms has the Wolf Grendel uppers in stock.

      • thedonn007

        Well, this is interesting, “These fine quality uppers are manufactured by Anderson specifically for Wolf Performance Arms in 6.5 Grendel”

  • alex waits

    I like it.

  • ReadyorNot

    6.5 Grendel upper for $400? Yeah I might be interested myself!

    The sound of fully automatic fire is like a symphony orchestra.

    • iksnilol


  • derpmaster

    This looks awesome. This very well could be my next AR.

    • Twilight sparkle

      I was thinking about doing a semi-retro build and I think this will fit that bill just right.

  • chuckldotes

    Is the piston adjustable?

  • borekfk
  • Doom

    I have heard that the steel cased wolf .303 is hard to extract. It would also be a shame to have a certain woman elected to a certain office and have all these nice imports banned.

    • jcitizen

      I’ve shot a lot of it in the Bren LMG – no failure to extract – in fact no failure of any kind. That said, I can’t predict what it will do in this kind of upper.

      • Doom

        BREN may have a better extractor? I was just seeing it with Lee Enfield rifles.

  • gunsandrockets

    That is very cool! I’ve always been intrigued by the Type 91.

  • Frank Grimes

    Gas piston AND made in some kind of China?


    • DW

      Taiwan is NOT China

      • argh

        so much different, having lived a couple of years in Taiwan and now living in China I’m still recalling from the unexpected culture shock. Its like saying America is some sort of Europe- sure a large part of the ethnic make up is from there but most other things are different

      • Frank Grimes

        And Canadian bacon isn’t just a slice of ham, right?

        • DW

          United States is some kind of England
          Austria is some kind of Germany

      • FWIW: They used to call themselves the Republic of China, as opposed to the mainland: People’s Republic of China.

  • ??

    How much Wolf could a Wolf upper shoot, if a Wolf upper could shoot Wolf?? No seriously, how many mean rounds between failure??

    • roguetechie

      Honestly I’ve got one frankenAR parts bin cleanup gun with rifle length gas 18 inch chrome lined bbl, no name M16 bcg, SI 7 position buffer tube, duostock with DIY “camel-toe” “pedicure”, lucid hd7, mismatched upper and lower, rifle length free float tube, and probably 5+ brands of parts throughout LPK and upper… Some of the parts have been used in other stuff, some new and mixed at random when the wife was feeling ” helpful ” one day and dumped 12 or so carefully sharpie labeled zip lock bags of parts into a single unlabeled quart bag.

      This gun has fired >2000 rounds of wolf military classic and WPA polyformance 55&62 grain steel case without incident or cleaning.

      It groups very respectably for even a mid range AR not built from random leftover parts.

      Now I know from multiple experiments that firing even 2 mags of steel case from a freshly cleaned rifle, then trying to fire brass case will choke even a $1500 AR pretty much without fail.

      Steel case works just as well brass in AR’s. It also has no real effect on parts life.

      The “common knowledge” regarding steel case and AR’s is bs, and

        I wasn’t trying to say Wolf doesn’t run. I was just interested to see maybe a torture test with their ammo and this upper they are offering

        • roguetechie

          I know you weren’t trying to say wolf doesn’t run. What I was saying though is that both their lacquered steel case (military classic line) and their polymer coated steel case (WPA polycoat) will most definitely work very well in the T91 upper.

          Especially since the T91 upper is a purpose built military grade piston upper that has been refined over two generations of production models and a few decades of time.

          Because of this factor alone, I’d say that Wolf probably doesn’t see any need to spend the time and money to do that sort of marketing. Personally, I think that asking for them to do something like that to “prove” their product is good to potential customers when we’re talking about a $500 piston upper of any kind is somewhat unreasonable.

          That goes doubly so for these T91 uppers which represent decades of testing and evolution that no other piston AR variant can claim.

          • ??

            Good point

      • The Brigadier

        Yes my former did things like that all the time. That is why she and I are no longer together. Good luck in your continued marriage.

  • fleetwrench

    Hammer forged barrel is it chrome lined or nitride?.

  • mig1nc

    Wonder if they have any plans to import the ROC military RAS that’s shown the wikipedia page.

  • Radioactive Pope

    This just made my day! The T91 is one of my grail foreign guns that I assumed would never be sold here, along with the Japanese Type 89, Swedish AK5, and HK MP7. I really hope they don’t mess things up, and that the barrel is chrome lined or nitrided.

  • Harry’s Holsters

    I’m ready for steel cased 300 Black!

    The upper looks like a cool option for the money. For $800 you have a non AR MSR that should be reliable.

  • TangledThorns

    Seems like a good affordable piston upper. Any idea how much it weighs and if we’ll see a shortened barrel?

  • George Phillips

    Are they selling this in California? I really like it.

  • DW

    Well yeah, I was sarcastic about the first point, got your attention. To say Taiwan is China IS akin to saying USA is England, but worse.
    You don’t like USA being called “some sort of England”? Taiwanese don’t like to be called “some kind of China” either.

    • Frank Grimes

      I don’t care about the sensitive little feelings of the enemies of the United States.

      The antigunners don’t like it when it’s pointed out that background checks are just a method establish gun confiscation, doesn’t change the fact that it is.

  • AHill

    Man I need to get IRG to bring some of these to Soviet Canuckistan. To the forums to make my voice heard as a consumer! Huzzah capitalism!

  • glenn cheney

    Holy crap, my .264 LBC barrels cost almost as much as a 6.5 Wolf upper…”rights to Piston, shall not be Impenged.”

  • glenn cheney

    Uncle Vladimir delivers again.

  • whamprod

    OK…… I WANT one of these uppers, and I want it bad.

  • Slim934

    So…..WHEN are they planning to bring these bad boys over?

  • Tom

    We voted for Brexit we are trying our best.

    • Frank Grimes

      Brexit or no Brexit, you still let them take your guns…

      • Dan

        And you continue to let the U.S. infringe on your freedoms. Voting is not a valid tactic because it isn’t working. So settle down there spanky.

        • Frank Grimes

          I’ve never allowed anyone to infringe on my Rights.

          Good try though, little man.

    • RA

      Agree. Great start in taking back your country! I hope you can reverse the decline and takeover.

  • BrandonAKsALot

    Thanks for the tip. I’m going to look into it. I’m not a die hard piston or DI guy. Both have their uses and advantages, so I wouldn’t be opposed to keeping an original gas system for an AR. Personally, I’ve just never seen the point of having a piston on an AR and still having a buffer tube. I guess to each his own.

  • The Brigadier

    Advantages and disadvantages for mating this upper with US barrels?

  • Kiran Buenafe

    Wolf, make 6.8 SPC ammo too!

  • first last

    If only they could build it so we could eliminate the buffer tube / receiver extension and install a folding stock.
    Basically, just give me a sig556 upper that is built to slap on my ar15 receiver lol

  • ReadyorNot

    “Wolf is making a 6.5 Grendel upper and it will retail for $400.”

    Is this upper in the same style as the Type 91 too? Any more info?

    • Nicholas C

      No, it is a regular upper.
