New H&K G3 accessories from Spuhr AB

February is coming to an end. Spring is soon here, which means exhibition time in Europe and time to tell our TFB followers about some new interesting products and news.

(Enforce Tac on March 2-3 followed by IWA Outdoor Classics 2016 on March 4-7 in Nürnberg, Germany.)

The Swedish based company Spuhr will be releasing some interesting news for owners of the Heckler & Koch G3. The G3 was designed in the 1950s and is still in service in many countries. It is likely that instead of investing in completely new rifle systems, many countries will opt for modernization and upgrades of their current G3s.

The Swedish Armed Forces version of the H&K G3A3 is called “Ak 4” (Automatkarbin 4) and was manufactured between 1965 and 1985.

The Ak4 rifle is today used by the Swedish Home Guard, and around 5.000 Ak4s will be getting some or all of these upgrades from Spuhr.

Spuhr is probably most known for their ISMS (Ideal Scope Mount System), which is used by Special Forces around the World as well as demanding individuals.

Before you continue reading, please note that deliveries of these parts will start towards the end of 2016, no matter how loud you shout.


Prototype of Spuhr’s G3 stock

Spuhr’s latest creation is a G3 Stock with LOP (Length Of Pull) from 12,5″ to 15,75″ (32 – 40 cm).


The stock is optimized for optics, like an Aimpoint as pictured for instance, or open sights which are mounted higher than the stock ones.

There will be cheek supports in different heights, but the intention is not for it to work with the original open sights as they will be too low.


The G3 keeps its original recoil buffer tube etc. with this design.


Above, the Spuhr G3 forend in aluminium, with the Spuhr interface.

The Spuhr Interface is described as a light weight solution that enables the user to mount accessories with a perfect fit.

The interface consists of two threaded holes with dual conical parts that will hold any parts securely with repeatability. The direct mount has the advantage of being stronger and sturdier than if using a Picatinny interface in between, with benefits like lower profile and weight.

The Spuhr forend has the same weight as the original plastic one (around 300 grams), but obviously opens up a new world in terms of configurability if there is a need to add lamps, lasers, bipod, grips or sights depending on the mission.




Swedish Home Guard – Not an official morale patch, but you get the idea.


In the US, Spuhr can be found at Mile High Shooting Accessories.

There is a new 2016 catalog to download for those interested: here.

Again, please note that deliveries of these HK G3 upgrades will start towards the end of 2016.

  • Sianmink

    Not sure why they went with a proprietary attachment system, but aside from that, good looking stuff.

    • Dracon1201

      It’s so you have to keep sending them those dollah dollah bills everyone you want to do anything to the rifle.

    • G

      The proprietary attachment system is called the Spuhr interface:

    • Håkan Spuhr

      Because it’s the only interface system working on more than forends, and that is really secure and repetable….
      Plus that the customer wants it….

  • MechanizedSwede

    400 ak4’s will be fitted with both handguard and stock. And will be on trial as a dmr in the regular army. The rest of 5000 stocks will be issued to the homeguard without the handguard. The rifle that is being used right now as a dmr in the army is the AI AW with S&B 3-12 (also used by snipers). Now they are looking for a semi dmr. Why some thing new when you’ve got tens of thousands ak4’s waiting on being upgraded and used 😉

    • Swede

      Interesting. What optic will be used on these regular Army DMR’s?

      • MechanizedSwede

        Unknown at this point. Possibly the old hensoldt 4×24 optic. These have been retrofitted with new picatinny mounts just a few years ago (for use in the home guards). But one can hope for a more modern optic such as an Acog and such. Time will tell.

  • DIR911911 .

    “February is coming to an end.” . . . safe bet on march 3rd

  • Very cool info Erik.

  • Gjert Klakeg Mulen

    We should get these for our AG3s here in Norway, would be quite neat.

    • Harald Hansen

      The AG3 is all but phased out now, but they did run an upgrade project during the Afghanistan mission. The result was the AG3F2 (“Forbedring 2” or “Improvement 2”). A Google Image Search will show a lot of pictures of it.

      • Gjert Klakeg Mulen

        Yeah I know, but that was only an upgrade of some AG3F1s, which is basicly an G3A4, the one with the collapsible stock. And they weren’t so numerous compared to the standard AG3.

        • Harald Hansen

          The F1 still has the Norwegian modifications, though? Hole through the charging handle, serrated area on the bolt etc?

          • Gjert Klakeg Mulen

            Of course it has , I was just generalizing.

  • ostiariusalpha

    That stock is very… Swedish. That’s all I’m going to say.

    • Some Guy

      It promotes a progressive ideology based entirely on ‘muh feels’ and has the highest rape rate in Europe?

      I don’t understand what you’re getting at

    • Håkan Spuhr

      So, how would you like to see it?

      • ostiariusalpha

        Ha ha! There’s no reason it shouldn’t look utilitarian; it’s a tool, not a toy. At least it isn’t a Tavor, where the exterior was designed before the internals.

  • Darren Hruska

    Looks quite slick. I don’t know how I feel about not being able to effectively use stock iron sights, however. I think a stock with an adjustable cheek rest, similar to what the Mk. 17 has, would be about ideal. Nonetheless, I may check this out later this year.

    • Håkan Spuhr

      The issue with the G3 is The low sights that forces the uses Of an ultra long stock.
      I would Love to Have irons there, but they need to be considerably higher

  • Rnasser Rnasser

    As much as I like the G3, it doesn’t make sense to upgrade it with very expensive stuff and still not get the light weight, ergonomics, flexibility and functionality of a modern 308 rifle.
    The unique Spuhr interface is particularly silly.

    • MechanizedSwede

      If you are on a tight budget, i guess it makes sense. Spuhr furniture is cheaper then buying new 417’s/LMT’s or Scars. And if you have alot of G3’s in stock, then i only see benefits. Then again with the spuhr interface, i guess for a civilian its kind of a pain. But for goverment contract, its does not matter. Cause the swedish army aint going to buy cool mlok keymod accecories anyway.

    • Håkan Spuhr

      Spuhr interface is ONLY interface working on a scopemount, or or spotting scope or Have serious repetability….

      So no it aint silly just because you didnt understand it….

      • Rnasser Rnasser

        Now, what I don’t undertand is your english….
        Perhaps you can explain to us what advantages the proprietary Spuhr interface has over the piccatinny, mlok or keymod, and how it outweights the fact that no one else but you use it.
        The only thing in a handguard that needs a good return to zero is a laser pointer, and the G3 is not ideal for room clearing/CQB anyway.

        • Håkan Spuhr

          The advantage over picatinny is weight. Our forend naked weight the same as H&K G3 orignal plastic forend, that is 190 gram,
          That is very little, and I don’t think there is anyone else that is even close.

          When you use picatinny you maybe have on for the bipod and one for the flashlight.
          That is mayybe 2″ of picatinny for each device you want to hang there, a total of 4″ picatinny, instead of carry around maybe 36″ of picatinny and very heavy forend on an already very heavy gun.

          The advantage compared to other interfaces is repetability and security, it does not come loose.
          The complaints against some of the others around are growing pretty big.

          The advantage is also that we are using the same interface on our scopemounts (no other interface works on a scopemount) so instead of having one interface for our forends and another for our scopemounts and interfacerings for spottingscopes and other things we make.
          So it’s a more and better complete system than what anyone else offers.

          However If a big customer wants our forend with another interface and they have a sufficient order, we would likely make it. But in this case with this customer, they have ordered our superior interface.

          • Rnasser Rnasser

            As you well say, in the forend there is only a need for about 2″ or so of picatinny rail on the 3 and 9 clock position for laser and ligth up front, and perhaps at 6 also for bipod mount. Some people want a fore grip too. There are several ways to use only fixed sections of picatinny rail on the desired places in the forend and leave everything else light, simple and flexible.
            The optic (either a red dot sight or scope) is better mounted on top of the action, with a picatinny rail that is the international standard and has (if properly made) a very good return to zero and possibility of quick detach.
            The forend does not really need to cover the possibility of mounting anything in any position, as that flexibility is wasted in 90+% of cases. It needs to be light, uncluttered, eronomic and easy to use and grip in normal shooting positions, offer good ventilation and allow to mount some thermal covers if one so desires.
            Your mount looks very well designed and your reputation is excellent, but I question the need to use a unique proprietary system with complex machining when the above mentioned approach would work equally well.

          • Håkan Spuhr

            The optic will be mounted top of action.
            But lasers will likely be mounted on forend.
            Possible use of Inlinemounted NV can be mounted on forend to, thanks to the fact that there is mounting space all the way.

          • Håkan Spuhr

            As I wrote a couple of times before our interface is the ONLY that works on a scopemounts and it also works on forends, lowers, spottingscopes , 40mm mounts, aimpoint mounts etc.
            There is no other interface that can do this, not a single one!

          • Håkan Spuhr

            When using a foregrip, the foregrip is usually rather close to the action, while the picatinny for the bipod is usually at front.
            Then there is need of two picatinnys 6 o’clock.

            Again it just proves that equipment should NOT follow “we have always been dooing like this” but instead accomodate for future needs. As noone knows what the future need or future equipment will be.

            But if you really dislike or lightweight forend, I don’t really get the point, you don’t have to buy ours. You can buy any of the competitors forends and be really satisfied with a product that doesent stand out and that you understand?

          • Rnasser Rnasser

            Good luck selling your rail system to anyone other than your home country…

          • Håkan Spuhr

            As said, we can make our railsystem for less good interfaces to when there is volumecustomers asking for it, so it’s no issue

  • FarmerB

    Thanks for that – It’s certainly pretty easy to get accused in Sweden (ask Julian Assange), they define a very wide range of sexual assaults as rape, and they prosecute vigorously. Many other jurisdictions started to remove the “rape” word out of criminal law, but some activists like to go the other way for their own (political) purposes.

    • 6.5x55Swedish

      Easy to accuse, hard to convict.

      • FarmerB

        Maybe, but accusation can still completely ruin your life.
