FN FNC Field Strip

The FN FNC is the standard service rifle of Belgium, and the gun that Al Pacino once used to shoot Tom Sizemore with in the face. This piston operated, rotating bolt weapon is an example of how the AK’s piston and bolt arrangement can be paired excellently with ergonomics preferred by Western nations.

– [Voiceover] Hey guys, it’s Alex C. with TFBTV and for today’s field strip, we’re going to be taking a look at an FN FNC, which is actually my favorite assault rifle of all time and yes, this is an assault rifle.

It is a select fire, it does fire an intermediate caliber, blah blah blah blah blah.

But really, it’s a terrific rifle.

I mean, these are very accurate, very well made guns.

They have a milled lower and a stamped upper, which is kind of unusual.

They’ve been adopted by the Belgian military, the Swed’s as the AK five and Indonesia.

So, they are somewhat prolific around the world, not as prolific as like an AK or an M-16, but still a very well-selling rifle in the grand scheme of things.

The first thing you’re gonna notice is it has two takedown pins that are similar to an M-16’s.

So, go ahead and pop out that rear one and pivot the upper away from the lower.

Now, you could field strip the gun basically for cleaning without taking the upper off, but it is easier to go ahead and pop out the front pin and just separate the two halves.

So, at this point, you’re going to pull out the bolt and carrier from the rear.

There’s kind of a buffer plate that you pull off the back, put some pressure on the charging handle and just pull it right off of there.

Now, once the charging handle gets almost all the way to the rear, lift the dust cover up a little bit manually and pull the charging handle out.

It’s similar to an FN scar or something like that and the dust covers a lot like an M-249, if you’re familiar with that gun.

So, at this point, you’re going to rotate the bolt, kind of like separating an AK bolt from a carrier, and pull it out.

Now, the firing pin is retained inside of the carrier rather than the bolt, which is kinda weird and there’s also a spring so, that’s actually all you need to do to field strip an FN FNC rifle.

These are very, very somewhat similar how they operate to an AK.

The bolt and carrier are laid out in a similar fashion but, the ergonomics are more AR-15, M-16 like so, this really is a great fusion of those two systems.

You’ve got a piston-operated rifle with better ergonomics, frankly, and these things are extremely reliable.

I put thousands upon thousands of rounds through this gun.

If you’d like to see a video of us shooting this and putting it to the test, I’ll go ahead and link to that in this in card here as well as the description for mobile users so, we hope to see you next time guys.

Big thanks to Ventura Munitions for helping us out with the cost of ammo.

See ya next week.

    FNC – The Original ARAK

  • aweds1

    Man, a semi-auto civilian version would be pretty nice! Guess we’ll never see that with the SCAR in production.

    • Robert Powell

      FN imported them for a few years, before the importation ban on “non-sporting” rifles. They pop up now and then online and typically cost around the same price as a new SCAR.

      • FN never imported them. Howco, Steyr, and Gun South did.

        • Robert Powell

          Ok, fair enough, but my point being they are out there and (occasionally) available. Unfortunately for me the price is going north on them and I never seem to have the cash when I find one.

    What’s the gun that Pacino used in Heat???

    • MeaCulpa

      Yes it was.

      • Pete M

        That’s the joke.

        • MeaCulpa

          *blushes in shame*

          • Steve Truffer

            It’s like Nagant revolvers and suppressing them.

  • The Swede

    I was issued a brand new AK5C variant (a green painted FNC with shorter barrel, picatinny-rails, winter ergonomics, Aimpoint and last round bolt hold open) when I joined the Swedish army in 2009. It shot 2 MOA at 100 meter if I did my part and I shot at least 10.000 rounds in total of live and blank rounds and it never had a single malfunction that wasn’t because of bad ammo (i.e primer strike but no round fired). Didn’t matter if it was in the middle of the summer or in the winter north of the Arctic Circle.

    Just a fantastic carbine by FN and I am amazed why it didn’t sell better. Thanks for making this video that gave me flashbacks to when I was a new recruit that tried to learn fieldstripping it as fast as possible while the officers were doing the best to stress me as much as possible.

    • MeaCulpa

      Heft, it’s a heavy SOB.

      • Evan

        It also tanked in the late 70s NATO trials because they rushed to get it done in time. By the time the Swedes trialed it in 80-81, it was good to go.

    • John Sjöström

      The AK5C is a really bad system if you ask me. The AK5A was really good and they could have just added a a different front-handguard with rail and top rail for optics and it would have been good. But no.

      Really bad shoulderstock that allways breaks compared to the old one, If you needd a short one you could got it fixed.

      Add rail that makes the 400m backsight worthless and replace the old front one with a shity flip-up one.

      Possibly the worst transparent mags in history for a 5.56 weapon. Allways breaks!

      The fact that AK5C became heavier (0,5kg more) then the A-version is the biggest fail of them all when the main reason for a upgrade was to make it lighter.

  • That’s an awfully lewd video, Trustfund-senpai. Who know Funco-chan was naughty enough to be field-stripped on Youtube.

  • Wolfgar

    The FNC fit me like it was custom made. The stock and hand guard shouldered better for me than any other assault rifle. Great video Alex, you know your firearms 🙂

  • datimes

    I bought one of these from a large importer of military surplus firearms and ammo about 25 years ago. It was supposed to be my every day shooter. It’s been in the safe unfired ever since. Thought I would pick up an S&H auto sear (when they were $3000) but held off. Now they’re gone. At least I now how to field strip it.

    • Bob

      Forgive me ignorance if the answer is obvious, but why haven’t you shot it? Does it not have the semi auto sear or is a kit?

      • datimes

        I wish I had an explanation. This is how one ends up with a large safe full of guns.

        • Bob

          Ahem… If you are having a space problem, I can help you with that. I would be happy to store and shoot any guns you have in the way.

  • SP mclaughlin

    because why not

  • Patriot Gunner

    I’m sure its a fantastic rifle, but man those welds on the upper receiver…crude.

  • Tritro29

    … Looking at that FNC from an AK perspective, it’s like looking at your attractive cousin in a wedding party. And everyone disapproving.


    FNC being one of my favorite rifles, the one sticking point for me is that the rear sight is just welded on. That’s just bizarre and takes away from the whole look of quality that the rest of the upper receiver has. Daewoo K1s came out only two years later doing the same thing, but has the rear sight formed with the receiver.

    But that doesn’t matter if your’e using optics anyways.

  • MadOnionSix

    Was issued one in ’91, never ever failed me but indeed on the heavy side.
    I can still dream that field strip…
