Hey guys, probably going to get yelled at for not searching better for a thread pertaining to this subject, but it's late, I'm tired, and she's frustrating.

Anyone know of a readily available upper to shorten this thing, because the 14.5" feels 20" long with an m203 on the end. Something 11.5ish

I say readily available because nothing seems in stock, and every one I talk to says I'm SOL on making this thing lighter

HELP!!
 
If your looking to keep the riffle as stock as possible you might be SOL, but if your not. The general go to for weight loss on an ar is lose the quad rail which looks extremely heavy on the mr223 plus whatever you have on it if anything, swap out the buttstock and depending if you have a optic on it or not change that out and the mount you use. If your looking to just swap the upper and are having difficulties finding anything in stock you might be better off just building your own to your desire. At that point it also kind of defeats the purpose of owing an HK riffle in the first place. Just my 0.02
 
What he said....

The MR223 is sorta a 416 clone, so it has a piston, heavy bull barrel and quad rails... That's what makes the 416 excellent for SF use.

That said, it is kinda overkill for the average Canadian GunNut... We don't get full cap mags, and certainly can't rock n' roll to the point you need the extra girth to manage heat.

I personally run a pencil barrel with a keymod handguard to get the weight down as much as I can for TacRifle games. I suggest you buy another upper and don't mess with the HK perfection...

I have the HK Parts 10.4" kit but didnt really like it once I got it mounted. I prefer the 16" heavy barrel for accuracy and increased range a-la the USMC M27 Infantry Automatic Rifle. YMMV...
 
AR15... heavy... muhahahaha

Like seriously. You guys take it to the range. The sheer weakness of civilians these days is unbelievable. It just never ends, hit the gymn, because if that is heavy to you then you have bigger health issues.

Y'know, it's funny, I usually respect posts from both of you guys, but in this case, you're both coming across as tools. I'd be really surprised to hear that either of you own 16" MR556 rifles... if you did, you'd understand. It's not that the gun's heavy (well, it IS heavy for an AR - just a hair under 9 pounds from the factory), but that it's awkward with the long, heavy barrel. All the weight's out front. If you shoot from the bench, it's fine, who cares. If you shoot dynamically in tac rifle matches, 3gun, or something along those lines, trust me, it's NOT the gun you'd choose. There's a reason the 416 is a short barrel.

Oh, and if either of you are ever in Surrey, I'll happily arm wrestle either one of ya - loser buys the beer. I'm 6'1, 210lbs, and work out all the freaking time. It's not that I'm a weak guy.

Cheers

Contrary to what you said, not all HK416 comes with 11" barrel. Case in point, both the French and Norwegian use 14.5" barrels as well.

Good point, I hadn't thought about that, but absolutely true. Are they the same heavy profile barrel as the civvi version? Honestly asking, as I don't know.

Where did you get this figure? According to Wikipedia it's 7.69 lb for the HK416 with 14.5" barrel.

My 16" was just under 9lbs with the backup sights and no optic when I weighed it back when I first got it. If I recall correctly that was without a magazine.

Specs for my 16" say 8.6lbs, and I'm guessing that's bare-bones, with no mag, BUIS or optic. Adding 1.4 lbs for a SpecterDR I was at 10lbs even without a magazine... much less any extra crap like vfg, light, or even a set of BUIS!

Most of the weight is the Rail/heavy barrel/GAS piston/Stock

You can change to a lighter rail and lighter profile barrel (don't even need to go shorter just thinner)

Mine ways in around the 8 pound mark with the PDW stock and the 10.4 416 upper.

Other then that... go with a whole lighter rifle.

(/me hugs my HK)

Didn't say it couldn't be done... just that it wouldn't remotely be my first choice of tool to do the job with the full-length heavy barrel. If she wasn't sponsored by/work for HK I doubt it'd be her first choice either...

Find a genuine 416 barrel, it's a slimmer profile than the mr556 barrel, and the mlok rail for the 416/mr556 is lighter than stock quads, unless you can find the uber rare, remington RAHG also lighter than the stock quads, but you will have to accept that it will be heavier than most comparable di guns.
 
If you can swing a C8A3 with RAS, you can swing a MR223.

There is minimal difference between a HK MR223 and the CC 15.7 L119A2 IUR. The HK has a 1" bbl behind gas block, the CC has 0.85-87" . In front of the gas block, HK is 0.8" and CC has a big bob of steel that is over 1".

All you need is a 13" after market handguard on the MR to make it work. MI made one and it is actually pretty cheap.
