FNH had their elusive SCAR PDW on display at SHOT Show 2015.

The PDW is based off of a SCAR 16S. However the upper receiver is slightly different. SCAR uppers usually have three holes at the front behind the sling loop. That is not the case here. As you can see there are no holes and the sling loop is not at the end of the rail but about 1 inch back from the front of the upper. The folding sights are a completely different design. Stock SCAR front sights are integrated into the gas system but the PDW has a rail mounted front sight. The rear sight is also a different design. The BDC is usually a knob but as you can see, in the following pictures below, it is more like a selector lever.  The handguard is flared at the front acting like a handstop. This one is 3D printed. It has internal rail mounts that slide over both side and bottom rails.




You can see the BDC lever as well as the polymer/rubber cheek pad. Underneath the pad is the stock release paddle. Similar to a HK MP5 you push the side of the paddle with your firing hand thumb and the stock and slide is unlocked. There are only three positions to the stock. Closed, middle, and fully extended.IMG_9496 IMG_9497


Just for curiosity sake I tested the Alpha Jacket to see if the SCAR PDW could fit.

    Damnit. I wanted one since they first showed it Many years ago.

  • James

    I can haz SBR?

  • FourString

    Wonder how long til we see these actually in the wild

  • Nice… Another gun Civilians will never be able to own. *yawn*

    • FourString

      Depends on where you live and how rich you are lol

      If they’re going to release any SCAR variant, I think they’d have better luck with the Mk. 20 SSR, since it actually does something different (7.62×51 DMR that’s not an AR-10 or based off a ’50s battle rifle). This thing just looks like an FN version of a super-compact AR with that one sliding stock thing.

      • Rabies

        they’re bringing that boat anchor too!

      • CommonSense23

        If FN is going to have any luck with the Mk20 they first got to get them to work well.

        • Raven

          I’ve heard people bring that up, what exactly is wrong with them? Regular SCAR 17s don’t have a reputation for unreliability, in theory the only change from a regular SCAR should be the barrel and the extended rail.

          • CommonSense23

            The MK17 has had a huge reliability problem, how it isn’t more widespread, I chalk it up to SOCOM not admitting they screwed up(how screwed up the evaluation process was) , and FNs and excellent support of dealing with it. Coupled with the fact that the 17 really didn’t replace anything excellent for some MK14s, the majority of people who have used them didn’t have anything to compare it to. At this point the 17 is a decent rifle, but is still outclassed by almost all its competitors.
            The MK20 though is absolutely a abortion still. Guns have large reliability problems, ranging from going full auto randomly, random shifting 5MOA or more, then shifting back, and going down hard with any debris in the action.

            Work for H&K much?

          • CommonSense23

            No just been issued a large number of SCARs and was responsible for the maintenance and fielding of hundreds. I personally am not a huge fan of the HK platforms cause I don’t like pistons in a AR. But while HKs do have their negatives it was never large scale reliability problems.

  • Squirreltakular

    Oh yes. Please be in .300 blk. Between this and that .300 blk Krink, I’m gonna have trouble picking a first SBR.

  • Dave

    You know, it’s ok. I can appreciate the cyberpunk aesthetic, and I get that a really short assault rifle might carry more firepower than a sub-machine gun.

    But in my opinion, there comes a point where logistics and the surrounding environment and what you plan on doing comes into play. Frankly, for all that cops and other people keep saying that you need a rifle for this and that, I’d end up going with a decent sub-gun. I keep seeing discussion on SBRs about the bullet, and will the bullet work as well with a 9 inch barrel as a 14.5 or whatever, and how much parasitic energy loss occurs when you fire a rifle bullet out of a short rifle barrel, and so on. The opposite seems to be true for a pistol bullet. The longer the barrel, the more energy 9mm generates. The longer the barrel, the more energy .45 ACP generates. Body armor that is rated against bullets fired from pistols, lose that rating when it goes against sub-guns. Effective cover turns into mere concealment. And you’ve got the benefit of sharing sub-gun ammo with the pistol of your choice. It simplifies logistics, tactics, and even strategy. In a bad situation, simple is good. If you want the benefits of an assault rifle, just use an assault rifle.

    He worried about fitting a PDW in his vest. The Matrix demonstrated that you can strap several subguns to your body underneath a trenchcoat, and it’ll be fine. They won’t show. This SCAR PDW? It looks like an expensive toy with little practical use.

    • CommonSense23

      What test have you seen that using a sub gun is going to allow you to penetrate level 3 soft armor.
      As for a PDW using 7 inch barrel and 5.56 you are talking around 2200 fps. The MP5 with a 9 inch barrel is in the 1300fps area. Still not enough to penetrate quality soft armor.
      And if you actually chambered a PDW in something smart like .300 you are actually getting pretty good ballistics all around.
      The sub gun firing pistol ammo had pretty much ran its course.

      • Mazryonh

        Velocity isn’t everything when it comes to armor penetration. Otherwise, the subsonic 9x39mm round developed by the Russians would fail at its task (subsonic armor penetration). The Russians also developed AP loadings of the classic 9mm pistol round as well, usable in both handguns and SMGs. Unfortunately it doesn’t look like anyone else has seriously looked into similar developments right now (making AP loadings of classic handgun rounds).

        • CommonSense23

          Velocity is kinda everything, it determines how much mass and surface area a projectile can have. Second where have you seen those Russian rounds tested by the way. I remember all ways hearing about how awesome all the Russian equipment is until I got hands on experience with it.

          • Mazryonh

            The 9x39mm Russian rounds have already been deployed rather widely and have seen action in places like Chechnya. And isn’t mass surface area already set by the bullet you pick, while velocity just determines its effective range and kinetic energy? Penetration/stopping power is more complex than that.

    • Mazryonh

      Since when do military personnel in the field wear anything like trenchcoats anymore? VIP protection might, but that wouldn’t look very professional. Besides, you only have the “energy gain from barrel length” thing halfway right. It’s subject to diminishing returns, and the projectile’s shape and mass matters as well. Furthermore, certain subsonic cartridges (like the Russian 9×39 round) are perfectly capable of penetrating most forms of ballistic armor.

      The Russians have developed something like what you’re looking for. Instead of making rounds like the 5.7x28mm, they’ve instead developed AP loadings of the 9mm Parabellum cartridge, usable in handguns and SMGs both. The platforms they use them in don’t normally have long barrels, though. Sadly there appears to be little interest in duplicating this kind of tech in the west, despite access to pistol calibers that might do even better in that department, like the 10mm Auto, despite the possible logistical benefits you describe.

        As for trenchcoats, it depends on certain special requirements of your deployment, that can have as much to do with diplomatic protocol as with tactics. I can not give you much detail since It remains classified, but during my stint as a PMC in certain african country, my team was deployed as a bodyguards of high ranking german official negotiating some delicate political matters. Due to our VIPs unique past and peculiar tastes, we all were outfitted with black leather long coats complete with very neat white, red and black armbands that served as quick identification signs. Locals were thrilled and our guest was so delighted that we all rewarded with special gold badges called “parteiabzeichens” or something like that. Sadly, mine was stolen when I wore it during my fourth grad sons ball games. Anyway, those longcoats proved very useful as one of my teammates was able to conceal the patrol mortar along with four white phosphorus bombs necessary for crowd control purposes. Of course we were also outfitted with small arms as highly customized full auto high point carbines and SW machine pistols and there were Dragon units hidden in the trunks of motorcade.

    Hopefully the charging handle is non-reciprocating like FN FNAC. I can’t imagine how often the charging handle got stuck by shooter thumb finger and cause it to malfunction in middle of high stress shooting scenario.

  • DIR911911 .

    anyone else notice the scar 17 in the new air force commercials?

  • Robert Davis

    Yes, at the show, FN confirmed a .300 Blackout version of this PDW will be coming.

  • Mazryonh

    Didn’t they release a CQC version of the SCAR-H rifle much earlier? Is this just the CQC version of the cancelled SCAR-L then?

  • noob

    3d printed handguard? is it robust enough to be a permanent part or is it just a demo prototype for a non-firing display gun?
