I'm thinking about buying an HK MR223. I noticed they come from the factory with either a 14.5 or 16" barrel. Is it possible to order this rifle with a shorter barrel? If so, what lengths are available?

If I can't get a shorter barrel from the factory, is it possible to get the barrel shortened legally?
 
Not possible to get shorter factory barrel (unless you can get your hands on a 416 upper). They also come in 20" but these are rare and I suspect not in demand.
 
OP, you cannot cut a barrel shorter than 457mm (17.99") or the rifle becomes a prohib. If you can't get a short factory barrel there are many aftermarket suppliers that can accommodate your needs.

I don't know about that, knowing HK I wouldn't be surprised if the barrel is proprietary to HK and a regular AR barrel wouldn't fit.

That's true, it would be like H&K to screw their customers like that. OP, I take it back. IF the barrel is a standard AR unit, then there are lots of suppliers to deal with. If it is a proprietary unit then you are out of luck.

Did a little googling, 2 problems seem to arise regarding a new barrel. First, HK uses a proprietary barrel nut, no problem right? Other manufacturers do this as well, problem is you can't buy the barrel wrench from HK. Second, the HK barrel uses a proprietary barrel extension, which HK doesn't sell either and has to be custom made.
 
Thanks for your replies guys. Any ideas where I could buy a 416 upper? I googled it but didn't come across any. And I saw a thread where someone asked Tactical Imports if they could bring them in and they said no.
 
Well expect to pay $4000-7000 for a real 10.5" 416 upper (yes only the upper)
If you can ever find one for sale down to south. Plus the import fee

Those are leak out from LE dep or individual officer
HK will only sell those mil spec upper to LE or military

And There are quite bit Rich Americans want that upper too

The way I understand it you can not cut a barrel on a restricted rifle at all. You can replace it with a shorter barrel but you can't cut it. If you cut it at all it becomes prohibited, even if you take a 20 inch and cut it to an 18 inch.
The laws are different if it is non restricted in which case you can cut it as long as it remains non restricted length and the overall length remains longer than the minimum OAL to be non restricted which I think is 18.5 inch barrel and 26 inch OAL.
Makes no sense but this is Canadian gun law and it isn't supposed to make sense.

Barrel wrenches are available. There was a group buy on HKPro.com not that long ago. I didn't pay attention to how it worked out because I wasn't looking for one.

The law makes no distinction between non-restricted and restricted long guns in terms of barrel length. It is perfectly legal to cut a 20" AR barrel to 18", but no shorter. If the barrel starts out shorter than 18" it cannot be cut, period. FWIW, the 18.5" barrel length only applies to keeping centerfire semi-auto's non-restricted. The 18" (actually 457mm) limit applies to all long guns, rimfire/centerfire, rifle/shotgun, non-restricted/restricted.

From the Criminal Code:

“prohibited firearm” means

  • (a) a handgun that
    • (i) has a barrel equal to or less than 105 mm in length, or
    • (ii) is designed or adapted to discharge a 25 or 32 calibre cartridge,
    but does not include any such handgun that is prescribed, where the handgun is for use in international sporting competitions governed by the rules of the International Shooting Union,
  • (b) a firearm that is adapted from a rifle or shotgun, whether by sawing, cutting or any other alteration, and that, as so adapted,
    • (i) is less than 660 mm in length, or
    • (ii) is 660 mm or greater in length and has a barrel less than 457 mm in length,
  • (c) an automatic firearm, whether or not it has been altered to discharge only one projectile with one pressure of the trigger, or
  • (d) any firearm that is prescribed to be a prohibited firearm;

You are correct that our laws are nonsensical and idiotic at best.

Here's a possible cheaper way of getting one (well, close anyway): ht tp://www.knesekguns.com/commercial/HK-MR556-416-Style-104in-SBR-Upper-556-235975A5-Modified (not sure if the barrel has been cut or it's been manufactured at 10.4". Obviously a cut down barrel would be a no-go for here).
 
Honestly. I've bought the 416 upper with the 10.4 barrel and it truly is the way to go.

Having said that. Don't buy from gunbroker. Head over to hkpro and just read what people say.

Also you don't need the whole upper. Ever now and then you'll see the 104 barrels available.

Good luck. They are close to unobtanium. But are worth it.
 
Well yes and No.

The 416 Bolt will work with the 416 barrel. But it wont work with the .223 barrel. (they have an extension on the 223/556 barrel so you cant swap the bolts), but otherwise You can put the barrel on any upper... just make sure you have the correct bolt/carrier

http:// w w w .hkpro.com/forum/hk416-hk417-hq/148788-comparison-mr556-hk416-pics.html
 
So you mean with 416 barrel you need a 416 bolt as well?


Btw. If we can get the 416 gas block. Can we ask gunsmith to make a custom 10.4" barrel for our MR223?
 
No the way around.

As long as you are not using the 556 barrel with the 416 bolt you're ok.

The 556/223 barrels had this D shaped "attachment" on one of the side. The 556/223 bolt/carrier are notched to accommodate it. The 416 Carrier/bolt don't have that notched in.

In the link I posted you can see it... if you search "bolt groups..." the first picture, top carrier has the notch (that's the 223/556 carrier) then when you search "Chamber area..." you can see in the first pic (that's the 223/556 barrel) they have this extension on the upper side of the barrel.

Meaning the 416 barrel doesn't have this extension to interfere with the carriers.

It sounds confusing, but if you look for it a few times you'll see it.
 
I see. I know what you mean now

So only MR barrel can't take 416 bolt
But 416 barrel can any bolt

So nobody try to get the custom barrel made yet?
