New: B&T APC9 SD – Suppressed carbine in 9×19 mm

APC9 SD links_resize

B&T from Switzerland is a relatively small but highly innovative company.

Their line of 9×19 mm SMGs and semi-automatic carbines is ever developing.

Yes, there is also a .45 APC but I presume the sales are very low.

When I visited the factory last year, only the very observant could what was in development and we were not allowed to take any pictures. The new APC9 is called APC9-SD (BT-36024). SD is short for the German term Schalldämpfer, Sound Silencer or Suppressor.

Full details aren’t know at the moment. Instead I will quote H&K’s website on their MP5 SD and highlight what’s of interest in the design:

“Despite its integrated silencer element, it has the same length and shape as an unsilenced submachine gun. Unlike most conventional silenced submachine guns, it fires standard ammunition types with the same effect. The use of special subsonic ammunition is not necessary. The integrated silencer element suppresses the muzzle flash extremely effectively, as a result of which the weapon is also excellent for night operations using low-light amplifiers.

This means you can take any 9×19 mm, not only a subsonic round, and the integrated suppressor will remove most of the sound and flash. Very Special Ops.

I’m pretty confident that the design of the APC9 SD barrel and suppressor and the MP5 SD are similar.

The carbine fires from a close bolt blow back system. Magazines are available in 15, 20, 25 and 30 rounds, all translucent and polymer. The primary sight is an Aimpoint Micro TL, with a very clever secondary iron sight with co-witness.

 

The APC9 product line. The new APC9-SD is in there as well:

The B&T APC9 “Suomi“, with fixed (pinned) suppressor and telescopic stock (non-standard).

For more information about the different stocks, check the previous TFB article.

Of course, all these stocks are available for the new SD version as well.

It would be interesting to see how the new APC9 SD would compare to the “Suomi” version?

      TFB: With Alex C’s departure and dudes with names and avatars like this, I am officially signing off! Not coming back. It’s been great.

        Hold on for a bit. I just reported him to Steve and I’m sure he’ll be history sooner rather than later.

        Wingnuts pop up from time to time. Especially around 9/11 which is crazypants Christmas.

        Wait, you love clickbait (the majority of the non-Alex C articles) but you have an issue with white nationalism?

        Honestly man, at least Hitler made the trains run on time. Writing at the “I’m pretty confident that the design of the APC9 SD barrel and suppressor and the MP5 SD are similar.” quality level doesn’t quite come up to that standard.

        • Nicks87

          Since when is Alex C so popular? There are plenty of other people showing off their gun collections on YouTube.

      • Cozmolyne

        It seems you guys have accidentally wondered out of your safe spaces. Schnee, Notorious, Minuteman: I welcome you to the real world, where people have different opinions that may rub you the wrong way. It’s scary, I know, but it’s time for you children to grow up and accept it.

        I was under the impression the gun community wasn’t experiencing the Vaginafication that men in other spheres of Western society were, but apparently I was wrong.

        • Schnee

          Really signing off for real this time. I’m sad about this because this was one of the sites that I frequented and it has been a good source for recreational reading about guns without all the normal “they are coming to take me away, ha ha” crazy stuff.

          Checked back in to find that we have a guy saying that at least the trains ran on time under hitler and someone saying that this is free speech and another to say I am a wuss for getting triggered like a snowflake millenial… I live in the real world. I like guns. I spend a lot of time and money collecting, fixing up, shooting, and thinking about guns. I used to come here for politics-free gun stuff. I didn’t get triggered or vaginified or whatever. I have a small amount of discretionary time in my day because I’m busy earning money in the free market in part to buy more cool guns. It’s not about free speech. It’s about the free market. Here’s the free market at work: I’d rather not spend my time having slappy fights online with people with IQs 3 sigmas below the mean. You create a forum where people do stuff like this, and I’ll just take my eyeballs elsewhere.

          And while we are being idiots, here are my political three cents: 1) I believe my gun rights are more likely to be taken away because of buttholes with screen names like White Nationalist and the reputation damage they do to gun owners everywhere. You are free to disagree. 2) I believe I am about as likely to end up in a gun fight with a neanderthal white supremacist who hates me and my religion as I am with a scary jack-booted agent of the new world order. That probability is just about zero. 3) All the open carriers could learn a thing or two from Israel’s nuclear policy (maybe we have them, maybe we don’t, but we aren’t talking about it and we are flaunting them). Most people who open carry are too dumb to understand that, and I think that makes society less safe. 4) And for the love of all that’s holy, will people stop making pistol caliber carbines that are straight blowback? Sheesh.

          Schnee out.

          • Cozmolyne

            Well you’ll find NO ONE was talking about politics or anything until you and your gal pals flipped over someone’s USERNAME. This website is not your personal blog nor is anyone obligated to take your delicate feelings into consideration.

            Don’t let the door hit you on the way out.

    • Minuteman

      You are an IDIOT for showing up here like that.

      • TheNotoriousIUD

        He probably shows up everywhere like that.

        • Minuteman

          Morons like that should be sentenced by a federal judge to get a vasectomy, the least.

          • HSR47

            So you’re opposed to basic first amendment protections?

            I’m one of the people that his ilk would have strung up from a tree or shoved into an oven when they had the opportunity.

            Still, restrictions on speech intended to silence such people are worse than the ill they claim to cure.

            As far as the specific restrictions on the content here (guns not politics), I feel it should be noted that, at least in this subthread, WN has actually been the only one really talking about guns.

          • Edeco

            I don’t think it’s a 1A issue as such, more like gentlemanly conduct. Apart from the name he seems to be keeping it cool. As for the name, I’m not a fan but someone’s chosen identity isn’t a burden to me, if he’s not using the place for a soapbox otherwise.

      • iksnilol

        Well, to be fair he’s at least being honest about it.

        That’s way better than those “I’m not racist but [insert racist comment]” type of people.

  • Nooky

    I wish my canton was suppressor friendly but it’s really really not.

  • LazyReader

    Exclamation point to accentuate the OK

  • Schnee

    When I saw those hex screws in the receiver just behind the barrel, I thought, “Wow, someone finally did something smart and bolted a steel MP5 trunnion into an extruded aluminum receiver!” Best of both worlds! Light! Delayed blowback! But then it said straight blowback and I said, “meh.” Really? A $3000 Cobray? Heavy bolts and blowback are cool in Uzis, but I expect better of the 21st Century and from the Swiss.

    • MPWS

      I agree, it is bit cheesy to do same thing over and over; that’s not exactly innovation. There are possibilities for delayed blowback other than HK type.

    • David

      There is a hydraulic buffer in the back if that makes you feel any better

  • Minuteman

    I like their GL-06 in particular. That thing is a marvel and can fire anything that fits its tube. 40mm grenades, Raytheon Pike. Perfectly laid out weapon system.
    Not a big fan of 9mm SMGs. I’d rather use 5.56 bullpups for that role.

  • thedonn007

    I’ll take two please.

  • Harry’s Holsters

    Aren’t they working on making their suppressors here in the USA? Could A B&T imported clone become a reality?

  • Vitor Roma

    Why we can’t comment on the Alex leaving topic? That’s evil, I learned so much with him. And please Alex, do a last video shooting your PSG1, pleeeaaase. =(

    • A bearded being from beyond ti

      I asked on the youtube channel when they’re gonna make a shooting video of that gun, i got a response saying that they had, but i can’t find any shooting video.

      Where is it?!?!??!

      • Jim N Jenna SK

        Same. Please I will do videos for free

  • Whatever

    I think I’m in love!!

  • A bearded being from beyond ti

    That VP9 is really cool.

  • J0shua

    I’m a bit confused by the HK statement, I thought subsonic ammo in 9mm (and .45) was just subsonic, not necessarily “special.” And wouldn’t using “regular” or supersonic 9mm still “pop” when the bullet breaks the sound barrier or does the design of the SD slow the “regular” ammo enough to bring the velocity from supersonic down to subsonic? And/or is the “pop” from a supersonic 9mm round through a suppressor just not that big of a deal as long as the muzzle blast is mitigated?

    • Alexandru Ianu

      I think it’s a ported barrel (like the MP5SD) – not the optimal solution since using heavy subsonic rounds, you’d me losing energy with no good reason.

      However subsonic ammunition is more expensive and it makes sense for some of the specific buyers that they’re targeting.

    • Anonymoose

      115gr 9mm at subsonic velocities is just .380. lol

      • J0shua

        So when HK refers to “special” they really mean “special” like James Bond saving the world with “special” 007 rounds. Awesome.
        Anyway, thanks for the responses guys.

      • JumpIf NotZero

        This is correct. Also, during development the B&T engineers had a feature to port the barrel or not with a switch. When I talked to them about it they said they removed that feature for the APC9 (it required their silencer to work correctly) during development. Its unlikely it’s in the SD model but possible.

  • Anonymoose

    An APC45SD wouldn’t need to syphon off propellant gases since it would already be subsonic. An APC300SD would be the Holy Grail, though…

  • YZAS

    Well, I was going to comment… but I decided to spend more time on my other interests, such as automobiles, so instead I’ll just leave instead. Bye

    • Edeco

      :'(

  • JSmath

    I’m probably one of extremely few, but I’d most like to see them make the MP9/TP9 in 7075 and send it over as a pistol (obviously not the model with the built-in VFG).

    Let the US market make the SBR kit; we’ll fix the trigger and the charging handle, too. 😉

  • Anonymoose

    Still no APC300SD. Maybe next year…

  • SPECTRE R&D

    Nice article. B&T magazines can be chipped or broken off at the feed lip fairly easily. I’ve seen it even occur from the weapon cycling – hope they look at a metal feed lip design in the future like the Sig Lancer design.
