FS2000 Loose Barrel???
1/24/2012 11:55:48 AM
FS2000 owners I need some input.
Just last month I bought a brand new OD green FS2000 and was so excited when I got it. When I finally was able to go and shoot it I took all my ar mags to test them out in my new toy. The gun ran perfectly. I probably ran 200 or so rounds through it without a hitch. I was very pleased with the performance.
When I got home I had to read the manual to figure out how to properly clean and oil the gun. I took it apart cleaned and oiled it and put it back together per the manual. I then noticed what I thought was a problem. While holding the gun I heard a rattle. I finally narrowed it down to the barrel. I then took it back apart and used the supplied allen wrench to tighten up the upper receiver. That didn't help at all. So I reassembled the gun and decided to give FNH a call in the morning.
Well, I called FN I told them them the same thing I just typed and their customer service rep stated that this was completely normal. I responded huh?? He's like yep thats normal. I told him you can shake it and hear it rattle, how is that normal? Doesn't that affect the accuracy at all? Still the same response. Yep, that's normal.
I really just want to know if it is normal or if this guy is just blowing smoke up my ass to get me off the phone!

Absolutely normal. The fs2000 barrel is held in place by two metal support pieces that are sandwiched by the polymer side plates. You will have some forward/back movement if you push/pull on the barrel. In the thousands of rounds others and I have fired through our rifles I have never heard of an issue because of it.

Mine seems pretty tight inside my upper receiver and I've put about 1.5k rounds through mine, I have heard of it though so I don't think it's too uncommon. I have the now discontinued standard optic model, just for reference.
If it bothers you, you could probably shim the metal brackets in the 2 clamshells of the upper as well as shim the barrel in the metal brackets. I would be cautious though as to not crack the polymer.
Besides, I don't think the barrel is going to kill your accuracy as much as your trigger. Mine breaks at a satisfactory target weight of about NINE AND A HALF POUND
. I would spend more time getting a neu-trigger than the fretting about the barrel.
The ps90 barrel rattles a little too, these things are blasters and 2-3 MOA rifles, not precision shooters.

This is my barrel slop.
Even with that play I still got 4" at 200 yards.

I appreciate the response. I guess I need not worry about it. It's a totally new weapon system to me. Thanks to everyone.

The FS2000 is built very differently from most other rifles. The sight rail is attached to the barrel, not the plastic receiver. All the receiver has to do is keep the barrel from recoiling through your shoulder and make sure the cartridge and bolt can find the big hole in the back.

Thank you for that. I have always wondered about this. As long as the sight rail/barrel interface is solid then you have nothing to worry about. It is no different than an AR with a loose upper/lower fit.

seeing that...I am so happy I havent came across one of them in my shop. good to know for future reference.

The aluminum pic rail is NOT connected to the barrel. Take your upper apart. The barrel is wedged between the two halves of the upper in the rear. Then mid way there is a metal support ring that is around the barrel loosely that then is sandwiched between the two upper halves. The aluminum pic rail is only held in place by the sandwiching of the two upper halves.

but it appears the the barrel is moving not just in and out but from left to right with respect to the picatinny sight rail. Seems like the gun wouldn't be able to hold zero. Mine doesn't seem to do this or if it does it's negligible. I'd put another call into Fn and see if they can explain why it's normal
they should all be identical although it's prob. ok as long as it shoots accurately
years ago I heard the same thing from S&W on a 45ACP pistol: You could wobble the slide and the barrel around on the frame big time. They told me the same bullshit when I called c.s.(they said "it dose not effect accuracy".... I thought, how come none of the sig, or HK, or 1911 guns do this?)
I couldn't hit the broad side of a barn with it and had always thought that I suck shooting 45's. I then realized it might be the gun and I promptly sold it.

Wow you're right. I saw the support crescent at the rear of the barrel and assumed it connected to the rail under the plastic.
Given that its amazing these things shoot as well as they do.

This makes me a sad Panda.

why does it make you sad?
The weapon was designed as a cqb carbine/grenade launching platform. Also it is still pretty damn accurate, I can ring steels out to 500 yards with mine. That's acceptable to me.

The barrel does the same on mine. I wouldn't worry about it, they are in use in many countries...and ours are FN factory produced at the same place all the rest of them are.

I guess one way to think about it is the barrel is *really* free-floated... (yes that's a joke)
