FN FS2000 Field Strip

The Belgian FN FS2000 is a very futuristic looking bullpup rifle that is sure to catch the eye of many folks at the range. Chambered in 5.56×45 and being very friendly to southpaws (forward ejecting with ambi controls), the gun offers a lot to the end user but has seen very little military adoption (Slovenia being it’s largest user).¬†In this episode of TFBTV, we take a look inside the FS2000.

– [Voiceover] Hey guys, it’s Alex C with TFBTV, and for today’s field-strip, we’re going to look at an FN FS2000.

The FS2000 is the civilian’s semi-automatic counterpart to the F2000, which is a select fire, assault rifle capable of full auto.

That would be really cool if this was a F2000, but unfortunately it is not.

That’s really one of the only big differences though, the other difference being that the barrel length is a bit different and the Flash Hider is pinned on.

So let’s go ahead and check the chamber, make sure that everything is empty, lift up the toilet seat, verify that there’s nothing in there, and it looks like we’re good to go.

So field-stripping starts with this little button here.

Go ahead and push it out, from this side, the right side of the gun.

And once you do that, you can begin to slide the upper and lower receivers apart from each other.

Also go ahead and pull the operating group out of there.

The bolt, bolt carrier and op rod.

Better move the piston.

You’ve got a switch here, with two gas settings.

Press this DTint down, rotate it clock-wise, and pull out.

To get the actual piston out, what I like to do is just grab a cleaning rod, a soldier would use a cleaning rod that he had in his kit, and poke it on out of there.

You can see the piston is almost identical if not completely identical to one found on a FN Scar.

This is what most people do to fully field-strip this gun, or well to field-strip this gun this is pretty much all that’s necessary, all that’s really recommended to do actually.

You can see it’s pretty simple, you can actually just wipe down everything, as long as you scrape off all the carbon fouling on the gas plug and the piston, clean the barrel, and wipe off the bolt, and bolt group and everything like that, you’d be good to go.

It’s an exceptionally well sealed gun.

Everything is very very tucked behind plastic, but as a bonus here, I’m actually going to disassemble the bolt group even though it’s kind of a pain on this gun.

You can see it’s got a plastic switch that serves to pull the, well after the cartridge is extracted, it pushes it up into the ejection shoot.

To remove the switch, pull down on this metal retaining piece right here, and it comes right off of there.

At this point, I wanna show you the FS2000’s interesting approach to anti pre-engagement.

You can see that lever located on the top that rides in a recess on the cam pin.

Once the bolt goes into battery, or starts going into battery, it lifts up that lever, and allows the bolt to move freely, or well not freely, but along the path that the rifle needs to go lock the bolt.

Very cool, very different than the OD’s Claw system.

Inspiring small arms designer’s, take note of this.

But to remove the firing pin, you can see that there’s a disk right, that I just showed located on top of the carrier, kinda towards the rear, under the lever.

Lift that up, and the firing pin will come out from the rear.

The spring is captive that’s on the firing pin.

After this, lift up the anti pre-engagement lever, rotate the cam pin, and pull it out.

It can be a little tricky if you have hands like mine.

After this done, you can go ahead and remove the bolt.

Now, there is a spring located inside the group.

I like to use the firing pin to just pull that out of the front.

And by the way, disassembling the bolt group to this extent is something I only do every 500 rounds or so, so I’ve only done it a few times.

Not something you really have to worry about that often.

But I just wanted to show you guys that it’s kinda cool how it works.

It pulls the cartridges out of the chamber, switches them up, and sends them forward, and ejects the cartridges forward.

A very cool design feature of the F2000 and FS2000.

A special thanks to the Venture Munitions guys.

We have done a shooting video on this.

Hope to see you next time.

    Great thumbnail image Alex. Made me giggle.

    • Wish I could take credit, but Steve makes the thumbnail images for our videos!
      I agree though, I chuckled when I saw it.

      • ostiariusalpha

        The only thing that would have made it more perfect would have been to play some Kenny Loggins and Michael McDonald quietly in the background.


  • gordon

    The FS2000 would have looked right at home with Barry Bostwick in Megaforce. Yeah, it’s that cool;-)

  • andrey kireev

    This almost became my first bullpup during 2012 panic

  • UCSPanther

    This rifle comes straight out of the Halo series…

    • The Brigadier

      You’re right Panther! its the carbine the Master Chief carries before he picks up one of the enemy’s energy rifles. I knew it looked familiar, but couldn’t place it.

  • Joseph Goins

    I want to get into the bullpup game, but I am too cautious.

    • gordon

      Try drinking. It has always worked for me:-)

  • noob

    Hnm. If you pulled the charging handle a few times and then had a bunch of complete unfired 5.56 fmj in the “poop chute” on a fn2000, could dropping thw weapon on its stock or muzzle cause a bullet tip to set off a primer in the poop chute and then start a chain reaction? Sort of like how only flex tips and round noses are recommended to be used in tubular magazines?

    • ostiariusalpha

      Not likely. The chute on F2000/FS2000 doesn’t press the ammo together under spring pressure as with a tubular magazine. It would interest to know how this “chute full of unfired cartridges” scenario would deal with the punch of the last case being forcefully loaded into the shoot from the rifle being fired; not so interested that I would test it out on my own gun though. The one real scary possibility with any ejection chute gun is having one or more bad primer strikes sitting in the chute and then inserting a hang fire behind them. Things would get really ugly at that point.

  • guest

    That has to be one of the most retarded guns ever designed. The similarities internally to an 80-90’s sewing machine are striking.

  • plingr2

    That lever mechanism is little complicated, but brilliant. I never saw something like that.

  • MrEllis

    I was hoping it made the “Transformers” noise at some point in the process.

  • The Brigadier

    The FN 2000 Yacht is a cool little rifle. I have not fired this gun yet, but I have fired one of the original PS90’s with the original larger cartridge. The French and the Belgian’s wanted the 90’s cartridge to be the same as their pistol. This was so the simpletons’ had to order only one size cartridge. The PS90 was the best SMG I have ever fired. Its stream of fire was so narrow you could put dozens of bullets through the same small hole in your target. Try that on full auto with a MP5 that is very accurate on single shot, but is spray and pray on full auto.
