First of... where to get one (and off course pricing so I can shop cheapest)

Second, do we only see the 16" version?

I've seen pics of the MR556/HK416/7 with the shorter barrel (maybe an inch past handguard)

I'd like to get something shorter then then 16. IF barrels are available seperate than that may be the route I'll go down.

Just trying to get as much info as I can before selling my AR and venturing the H&K Route.

Any and all help is appreciated.

Having said that, any non related/smart ass comments will be ignored.

Thanks
 
CRAFM and TSE for sure. remember to ask specifically for the A1 version...

if you want to go 11.5bbl, you will have to get it done custom.

Joe at Dlask arms did one for a local guy a few years ago, i would suggest you PM the rifle owner for details...

here is his info.

he did his MR223 to a HK416D specs i believe..

1. Any dealer that carries HK (many of them do). Off the top of my head, Wolverine Supplies. A new MR223A1 will probably run you mid $4k-ish. There's one used on the EE for $4k. If you don't need the A1 version, you can probably source one for mid $3k-ish. The metric flash hider will run you another $100.

2. Yes, you'll only ever see the 16" version. The 10.4" version is exclusive to the HK416. The HK416 upper alone will set you back in excess of $6k, and there are only a handful in Canada. They're very nice though.

If you want an HK, my advice is to find a nice minty standard MR223. It doesn't really matter if you don't have the pin offsets that the new A1 does, because you won't necessarily want to run anything except the HK lower anyway. And for a potential $1,000+ savings, well...

The HK MR223 is heavy, but it's probably the best AR that money can buy. Good luck!

While you can do this, there are apparently differences in the gas system between the two. It's not just as simple as switching the barrels out...
 
I heard that there is a possibility to shorten the barrel.

Agreed with Blaxsun, no need to get A1 as only you want to change upper.

DO NOT do this.

Cutting ANY barrel (regardless of clasification) below 18" will create a prohibited firearm.

Cutting any semi-auto rifle or shotgun below 18.5" will turn it into a restricted firearm, although it is legal to do so as long as you don't cut below 18".

Honestly, there's nothing wrong with the factory 16" barrel. There's not a huge difference in weight (although you will notice some), and even the HK416 is a tad front heavy. You're going to see higher accuracy with the 16" barrel anyway.

The thing to also keep in-mind is that you'll be pushing $4k for a first generation HK MR223. Assuming you can source a factory barrel, by the time you find a gunsmith to retrofit it and tweak the gas system - you're going to be well north of $5k.

The HK MR223/416 feature an awesome barrel and phenomenal gas piston system. They run clean, cool - and are ultra-reliable. That being said (and not to talk you out of HK), if you want a CQB-length barrel there are lots of other top tier alternatives: KAC, Noveske and PWS (if you want to retain a piston system).

I was thinking of this set up also, thank you Blaxsun big $$$ to have one.

No problem at all. You don't typically see many HK MR223's up for sale, because it's probably the ultimate AR (I think one would be hard-pressed to wear the thing out in their lifetime). But with the new A1 out, this will probably depress prices on the first generation MR223s a bit - making them a bit more affordable.

I am happy with 16", I'd rather spend those money on something else :) I got my used, but damn it is sweet shooter

Yep, a nice Noveske or even an LMT is going to be pretty close quality wise (LMT maybe not quite as refined as the Noveske and HK) but it'll be MUCH more affordable.

You can even get an LMT piston gun with a 12.5" barrel for substantially less.

Is it possible to fit a barrel from another manufacturer on these? I have experience building AR-15s and a shop full of tools and parts but I've never handled an MR223 before, much less so taken one apart to see how the barrels are fitted on.
 
The Gas Block on the 10.4" Hk416 is different than the longer barrels. The longer barrels vent the excess gas out to the front of the block, while the short guns vent thru the barrel.

It obviously possible to get a barrel manufacturer to make a custom barrel - but it's going to be a long hard road.

You need a custom (proprietary) HK barrel nut wrench to remove the barrel, the barrel extension will then need to be removed and inserted on the new barrel.

Then your going to need to figure out the gas port on the gun. You can plug the gas vent on the gas block, or you can try to get a new block (made or bought via an Hk source)

Its not impossible, but it is not easy.
