Dear folks,

I recently put my hands on a brand new Mr223 A3, it's a factory 11" RAL8000 version with modified muzzle device to accept a rotex Suppressor.
Needless to say (on this forum at least), this is the closest you can come to the HK416A5. As a consequence, the expectation bar was and is understandably high.

Benchmark: I have shot and own a selection of competing .223 SBRs such as Mk18-like AR's, SCAR-L 10.5", SIG553 and G36C

First feeling & Ergonomics: 4.5/5
Out of the box the gun feels solid as a rock. It is right on the top of the league with the SIG553. Upper and lower sit together really tight. The A3, near the rear take down pin has some sort of device which puts tension on the take down pin. There is no rattle whatsoever (not sure if I'm describing it in technical sound terms, but the effect is this). The slimline stock is really flat on the cheek, but then again it's not called slimline for no reason I guess. Stock pistol grip sucks, I don't like the angle (this eats away 0.5 out of the overall rating) - I replaced it with a spare Ergo I had. The safety switch has a very positive feel to it - light years better than the G36C one. The iron sights that finally come out of the box, are really nice and actually as useful as they look. The new handguard looks awesome and has a solid feel to it.

Manipulations 5/5
Manipulations on an AR are high speed, the A5 imporves a bit on the traditional Ar15 in these ways: Enhanced CH (better angle); larger bolt hold open paddle (bigger, more surface and good texturing). For lefties there is a little lever to release the bold also on the right side of the rifle. Same goes for the mag release. Note that these little adjustments are not a gigantic leap in technology BUT finally HK puts it all together in 1 package and they all fit well together. No need to go aftermarket (finally). Trigger guard has also been enhanced, although I never had an issue with the old (flat) one. At the range working around the platform is pleasant, all the parts work well. the trigger is crisp and the pull is smoother than my other ARs or SCAR. Not gritty but also not comparable to the SIG which is still superior IMO. You can shoot fast mag dumps but still achieve good accuracy

Accuracy 5/5
I shot with iron sights only at 100m, and the accuracy is outstanding. I have 3 reasons in mind why that is so. 1) Iron sights do their job extremely well. I feel very comfortable with them, they're as solid as BUIS can get (unlike the SCAR) and are fully adjustable in an intuitive way. They are superior to the KAC Taupe I have on the Mk18 - and that one was already pretty good. 2) The trigger is smooth enough so that from day 1 you can pull off some nice shots without having to find "the spot". 3) the barrel is heavy as f**k and 11" long. Among my SBRs with iron sights, the MR is the highest scoring platform. The SCAR and the Mk18s come second, the SIG553 third and the G36C is the worse of all (borderline useless with the stock iron sights made of plastic btw). The SIG551 scores better with stock iron sights, but it is almost full length so not really an SBR for me. Adding the suppressor did not change the POI a noticeably, here is where the ultra heavy barrel comes in handy I believe.

Agility 5/5
The rock solid feeling and heavy accurate barrel come at a price, especially if working with a suppressor. With irons and suppressed, the gun was a liiiittle nose heavy. Comparable to the SIG553 though - which left me positively surprised given that the MR is longer. I am curious to see how it performs at 300m, eventually if performance is consistent one may really wonder if a 14.5 or 16" platform is justified. Granted i'm more of a short range mad max, for me anything beyond 300m is unappealing. Anyway the nose-heavyness can be easily offset by some push ups each morning. No deduction in points for the excess of weight given the positive impact on accuracy.

tacticool 5/5
This gun is AWESOME. For ages I was not sure if to SBR a random MR223 or not. Thank God, and also thanks to Baljar and Montrala I did not. They said that HK eventually could and would bring an SBr to market as the respective German authority approved it back then. Well the gamble paid off big time! The package is as sweet as it can get. With the exception of the muzzle device and pistol grip, we get all of the HK416 A5 furniture. including iron sights which on the market are priced well over 200€. Add the RAL8000 magic and it does not get any more tacticool than that. I feel kind of sorry for those who already own an SBRed Mr223.. A somewhat expensive operation for a package that is now available out of the box for a surprisingly competitive price (for HK standards). The only thing missing is the adjustable gas block. But I ran the gun suppressed without any noticeable difference. I wanna torture this thing to see if HK really does things right.

price point 4.5/5
I managed to grab one for a price that is 70% of what a new SIG553 would cost me. it is around 35% more expensive than the average AR15. In the price range, I would say that the MR223 is for once not the "usual" HK ripoff. The Haenel in 223 offers the same technology for less price, but not a lot less. I'd say the Mr223 is the best AR15 platform money can get you across Switzerland. You can plink .223 for less money, but the collector's value and historical background of the MR223 would be missing.

overall rating (not an average) 5/5
As far as civilian legal HK rifles are concerned, this is an amazing package for a competitive price. We could rant about the missing adj. gas block, but then again years ago we would have spent hundreds of extra $$$ on top of an inflated base price just to cut the barrel! If you can or where thinking about grabbing one, don't hesitate to pull the trigger! Will try to do some more testing with more pictures these days. If you wish to see some specific parts, let me know!

I've done some random fast magdumps as well as some accuracy shooting from the bench at 100m I also got a clip of the mag dumps:

Damn bro...take it easy!! Slapping that trigger like it owes you money. Press, reset, press, repeat. That said nice pics, definitely jealous... I refuse to buy an MR556 until (if ever) HK/HK-USA decides to start incorporating the A5/A3 improvements to the US line of firearms.

Beautiful, I wish we'd get the short barrels over here in the states. Even if it was just as individual parts and not whole rifles

thanks for the tip :p had little money on the prepaid card for the range, thus I was a little hard on the trigger to squeeze off the remaining mags before shut-down!

I'd love to see your review of your Sig 553. Have you done one and, if so, where can I find it?
I have a clip with the overview of the whole SIG 55X lineup on my channel! -> from the clip above you can go to my channel and see it :)

Some ideas:

- less trigger smack, more conscious reset and pull
- no need to smack the bolt open device, mag in and move your hand to the foregrip, you can conveniently use your trigger finger, shortens the reload significantly
- weapon to safe with trigger finger is good practice on ambi guns when it leaves the cheek, no reason to put the gun away "unsafe" in a gun that goes to safe uncocked

in addition:
MR223 11" is able to shoot 1/3 MOA (about 1 cm) group at 100 meters with Hornady 75 gr HPBT bullet (TAP and super match) both ok but a bit different location of the group.
Zero at 100 meters, at 25 meters -4(5) cm at 50 meters +2 cm (optics mounted on Weaver mono block about 7.5 cm from barrel center).

Geras, that accuracy sounds very good!

What kind of scope were you using and have you chronoed any velocities from that 11" barrel?

Simon, i used Schmidt&Bender 2.5-10x56 (big and heavy)
I have no chronograph to measure velocity, sorry.
Other ammo tested : GGG 69 gr HPBT, Hornady match 75 gr. (group for those was about 1 moa)

Baljar,

thanks for the tip :) I was window-shopping those HK parts on ZIB some days ago.. Tactical Arms.EU also has some on stock. One *could* put up some veeeeeery interesting pieces of kit with that batch. Granted it's some sort of grey area, you can buy something which I can't, and vice versa - if you know what I mean.

the 416C would be a unicorn, especially based on the genuine PDW stock, but I guess that a special buffer spring etc. is needed as well, not to mention the BCG? Where can we source those parts? There is not a lot of material on the 416C out there...

I bet our US based friends are drooling over this stuff ;-)

I have recently discussed with my dealer to cut my 16in to 10,5 and using a hk416 gas block. He said that he will not do it due to the fact that my A3 barrel is chrome lined and that it would ruin the barrel. He suggested to purchase an 11in barrel from HK and swap it.

We cut one and there was no problems. Apparently HK knows how to put chrome in place. But if you can just exchange barrels, why not?

There are plenty of genuine 416 parts around in Germany - if anything, now it's the time to go for the unicorn build.

I am curious about the lead time for HK spare assemblies such as the barrel.. keep us posted about the project!
