MR762 - No Love?

I borrowed MR308 from a friend for few months. Very soft shooting, it surprised all who shot it.
I did not shoot a lot with it, just one trip to 1km and other to 500m.
I could not get the accuracy out of it, it would have required shooting more rounds to get used to it. Just looked at those targets by chance a day ago and when I shot 4 rounds at 100m, they were like 3cm separated but both groups were 0.2" in size. So double grouping vertically, probably my grip or other stupid shit I do when focusing on paper.
I was not shooting match ammo though.
But out on the long range it was not bad, I got the 1km target 2/5 out of shots until light was completely out and its size was about a kneel high. (Depicting prone enemy)
After returning it to him I got a really bad rifle fever. But I resisted it and bought 223 ammo and loading station instead.
My one friend who shoots 308 a lot did get consistent sub moa with bulk ammo at 300m. I was sure that the first group was just luck but he kept on doing the same. He added the MR to his shopping list too. He had never even shot semi AR before and his eyes were shining. Great day.
Here in Finland the cost of MR308 seems to have risen. We have not gotten any new guns from Germany since 2019. The used ones are now sold for new ones price.

1 in 11 twist barrels. We accuracy test every rifle out of the facility and it is not unusual to see ragged hole groups (note that these are shot from a massive machine rest that clamps the gun by the barrel nut). They are designed around M80 ball ammunition so do best with projectiles around 150 grains. We test them with 168g FGMM and they shoot exceptionally well but trials with 175g SMK Blackhills or Ruag did not shine. The SDMR rifles were transitioned to a 1 in 8 twist as the intended issue load was M118LR.
If you see two groups from the rifle that is the interaction of the feed ramp with the round during loading. Changing the load or the neck tension will resolve it.
The MR762 set up has a rather soft gas balance. It is not as violent as the HK417

I’m tagging in. I hope this doesn’t turn into ”get a SR 25 thread“. I agree there doesn’t seem to be much love here for the MR762. Common complaints are it’s to heavy or to expensive. Neither of those two things would deter me. It would be nice to hear from those of you that have one or have shot one. I’ve been looking hard at this rifle as well. I thought I wanted a scar 20s but I’m really drawn now to the HK.
too expensive isnt a factor much anymore. Given the current climate where you can get a MR762 for $3800, MWS go for around 4k second hand and SR25 will run you closer to 6+
I agree with you. Like you probably I’d like to here some feedback on the MR762 not “it’s to expensive you can get better for less”. I’d like real feedback on the rifle not opinions.
Interesting,
Did they ever figure out the barrel thing, I know they had some dispersion issues for years that was thought to be associated with the odd ball barrel twist.
From everything i heard recently, they are shooters,
I think there are few little reasons why you don't here much about them here. I think they are a bit heavy for the class, are only available in basically configuration so if a 16 inch 308, they may not be very appealing, use expensive odd ball mags.
The MR762 is one of those rifles that I think is cool, and I would like to add to the collection, but since I have 2 MWS's and an ACC, it is always low on the priorty list. I am glad that they produce them though.
I don't think weight is the issue, the kac and lmt are battle proven performers with accuracy and acclaim over a long period. Weight difference amongst the 3 is immaterial. Of the people that I know who have purchased recently the decision really came down to that and it seems only HK fans are excited about it. Just my observation on the last point
I recently picked up an MR762A1 and like it a lot - compared to my previous 7.62 shooters, LWRC, LMT, SCAR as well as Armalite. My purpose for this 16” rifle is send multiple rounds down range into a full size IPSC silhouette @ 50-500 yds and hence my optical choice is a simple 3.5X ACOG. The FGMM 175 SMK’s do what I want reliably. So for my purpose weight is good, the rifle is extremely reliable and accuracy is more than acceptable.
For me it is a niche firearm, I have others for longer and shorter engagements.

Have not handled the MR762, but like others, looked real hard for real long at getting one. Passed on one around $3-3.5k a few years back when I finally concluded I wouldn't shoot it much. Since then, I caved and bought an LMT MARS MWS. For me, the monolithic rail and easy barrel swap was the selling point. I had plans to buy a 20-24" 6.5 barrel for it (mine is .308), but bought a bolt gun in 6.5 instead, so it still just has the factory 16" barrel. I truly love the LMT MWS platform and can't imagine replacing mine.
Thats the sort of the thing that makes the HK a hard sell if one is looking for a mil large frame gas gun and they are not big HK fans, The MWS just works well in so many areas.
Slap a light weight 13.5 barrel in it and an RDS and it can do carbine stuff reasonable well.
Slap a 6.5cm barrel and it outclasses most of its 308 peers at longer ranges.
It just sort of works and for the marginal cost of a spare barrel, one can really do a lot of stuff with the MWS that one would have to spend alot more to accomplish with some other manufactures.

I've owned the MR762 shortly after they first came out. Yes they are a bit heavy but my LMT MWS with the Magpul PRS stock is even heavier. So the weight is not a problem for me. Mine shoots 5 shot 100 yard groups @ 100 yard about 0.8 moa sometimes better using 168 SMK's. I have a Bushnell 3.5-21X50 Tactical Elite DMR on it. Then again I don't go hiking over hill and dale with it.
I Love the HK MR762A1 I got this few months a go ( brand new $4000 is come with only 1 20 rounds mag 
+ 4 extra 20 rounds Mags $360-$380 ), Is one of My collection AR 308 guns , so far I only shot like 10-15 rounds ,

I’ve had the Finns show up with them to DM Courses I ran over there several years ago, but those were German guns, not from the US market. The magazines seem to be a starting point where Hk solved the problems associated with a straight stack, and made an optimum curve for 7.62 NATO, as well as the spring weight necessary to lift the cartridge stack and drive a low coefficient of friction follower up through the body. I like the magazine design a lot for functionality, but they are noticeably larger than any SR25 magazine all around.
I don’t recall any malfunctions in any of the courses where Hk417s were present, but we weren’t seeing large sample sizes. Most had SPR-type AR-15s, 16” AR-15s, 20” AR-15s, and I think one 24” AR-15 was at one of them.
I also never saw any of the AR-10B ArmaLite Inc. rifles malfunction in Sniper Training events or high volume courses we did. Those were all M14 type magazines that performed very well.

Hk Mags dried out some time back. Available now for 1/2 the price of an unavailable KAC mag!
It's crazy times cuz you can buy a new HK barrel for the MR762 for 450 shipped, try that with KAC! Firing pins, bolts are available. I've always hated HK for expense and lack of availability but darned if they are not the shining light on factory large frame autos.
I checked out my brother's MR762 and the fit/finish is typical HK....beautiful. tight like a match rifle but it's silly you have to use a bullet to break it down but I remember SR 25 being tight when new, requiring a tool or bullet to get the pins pushed to break it down.....
I had one of the origional pre ban SR25 Carbines from Knights and I loved it but got no support for accessories like extractors, firing pins,and other support parts. I understand the love for both but if you just look at availability of mags, parts ect....I feel HK wins.

I have a rare hk 911. It was the end of the 91 profile barrel. Instead of 1 in 12” twist its one in 11” as does the mr 762.
it also shoots Sierra 168’s hand loads at less than MOA. At least it did 30 years ago when i tested it last and put it away for SHTF time.
Bought a qty of Lapua brass and 169 grain better ballistic shape sierras to test and a better scope Just to see

Hey sorry, just seeing this. Pretty reliably 1.5 moa with fgmm. Getting just under 2450 fps.
Shooting the EU version MR308 with 16,5" barrel for some time now. H&K guarantees 1,5 moa results for a 10 shot group with decent factory ammo. With handloads so far I reached 0.62 moa results at 100m ranges, but I think I am a terrible shot. It does seem to like 167/168 grain hpbt bullets a lot like the Sierra Matchking and Lapua Scenar. For chuckles; I miscalculated the bullet seating depth of the Scenar 167 grain and ended up with a COAL of 2,736" (quite short), but for some reasons it resulted in one of my best 10 shot group so far.

This is my more recent group with my friends MR308. 43gr of N150 with Scenar 167.
Shot in the dark using flashlight, was just supposed to check his MV and also zero.
9 shots, I first shot only 7 rounds but then shot 2 more.
I really think that in daylight and better conditions (was 10F) I could do 2/3 of that.

On the HK MR rifles they don't use normal take down pins, they use a specific locking one that is designed to reduce any movement between the upper and lower. So you push in the center of it to unlock then it can be removed.
Yup, there's definitely zero play between receiver sections. The downside is that it's a pain to unhinge in the field, at least compared to other large frame AR offerings.
Pro Tip: you don't need to buy the fancy Geissele trigger like I did. Just strip the lower receiver like you're going to have it Cerakoted, marvel at the strange proprietary trigger assembly that lets you place the rifle on safe without the hammer back, then proceed to re-assemble it and puzzle at where that extra part goes?
Result: the heavy 6-ish pound factory trigger turns into a really nice 1lb single stage. (actually don't do this)

In my experience, the takedown pins loosen up enough over time so you can push them out with a finger. Initially I had to use a pin to push them out.
Found a new handload recipe for which I will use as my default load. I was frustrated for a long time to see quite some vertical stringing with various other powder loads, but this one seems stable. I doubt I can improve any further on my H&K MR308 16,5" semi auto.
Usually I fumble up 3... 4 shots out of 10. The ones I don't mess up group really tight. I am pretty happy with the potential of this new load.
Lapua Scenar 167 grain (GB422).
Vihta Vuori N135 38,60 grain.
CCI LR #200 primers.
RWS or Lapua .308 Win brass.
COAL approx 71,8 mm (jump +0,024" of lands).
Muzzle velocity around 700 m/s for my 16,5" barrel.

Update. Got a chance to shoot Army test model hk 417s recently. They’re beat up on purpose mind you…but in one 10 round mag experienced 3 malfunctions. Recoil seemed lighter than the notoriously over gassed MWS…but overall, I’ll keep my LMT.
Since we're talking MR762...I'm still amazed how accurate it can be. This barrel has about 3000 rounds through it
I can't speak for the HK417, since I never handled one myself. I've put more then 2000 rounds through my MR308 now, mostly all various kinds of handloads and factory ammo and I genuinely can't recall a single malfunction. For comparison: recently got myself a Diamondback DB10P13 though and put a couple of hundred of rounds through it. Already experienced FTF's or other malfunctions, but nothing serious which couldn't be fixed at the range. Although proprietary and expensive, the HK mags are very reliable in feeding ammo to the rifle.
Mag reliability and availability are great points. I could not find a set up that worked with the lmt 7.62 piston barrel suppressed. Mag pul and larues both jammed with many different spring/buffer combinations. LMT has an adjustable block for the piston now that might help. I went back to DI in my mws. Haven’t had a malfunction w pmags since. And love that they’re low cost and widely available. I will testify, however, that HKs piston system is very smooth in comparison. I don’t intend to dog it by any means.
Same. I've had mine since 2015 and it's shot some FGMM but mostly my own loads, and I can't remember a single malfunction in all that time. It really seems to chew through anything I throw at it, surprising considering it lacks an adjustable gas block. The only issue I had with it several years ago turned out to be scope-mount related and had nothing to do with the rifle.
I Love the HK MR762A1 I got this few months a go ( brand new $4000 is come with only 1 20 rounds mag
Update # MR762a1 LRP III #

I picked up this MR762-A1 earlier this year. It's been cut down to 14.5". I use it for Ariel pig shooting hence the Aimpoint CompM5s.
My only complaint is it's heavy (compared to a similar sized 308 gasser) and the trigger sucks.
I initially zeroed it with some old M80 ball at 50m and I was shocked at the accuracy. More than acceptable for my type of work.

MR762 is a sweet shooter, accurate, easy to clean & maintain, and utterly reliable. Blows the HK91 away (unless looking for an auto host)......buy now
When H&K says they guarantee under 1.5 MOA, they really mean it. 135 rounds shot so far, 80 of them from doing a barrel break-in similar to the M24 SWS with Norma M80. I like the HK416 barrel profile they're using in the MR556s. But I don't agree with them moving to a contoured barrel profile for the MR762s. The LRPIII packages still use the heavy barrels fortunately. But either way, using that HK French Cannon Steel, means you have a stellar weapon system either way.
This is my first post and I'm new to this world. Figured I'd chime in with my limited experience on the MR762.

If $3800 isn't overkill for your particular situation, you should have bought it already as they are relatively rare.
forget the price provided it's accurate but the prints in this thread don't create any warm fuzzies there
My MR762 got so much love, I got a 2nd one; this is a recently finished image of the 1st rifle.
If you want to see the image at the size I shot it, it's here. Sroll down to #451.

I just picked up a FDE MR762 from Cabelas for $3599. It's the first one I've seen and I can't find any info any where on it. I have a black MR762 and love it. I have a Nightforce 8-32×56 nxs on it and it is extremely accurate. I have no complaints. I wished it was FDE when I got it but they were unheard of a couple years ago. So when I stopped in at our local Cabelas for some 300 win mag ammo and seen it in FDE, we'll now I own 2. I have several HKs so it will fit in fine. That is a better price then the $4100 I paid for my first one.
They can call me when they come out with a 6.5 CM. Not going to waste an extra 5lbs of gun weigh on 10% more performance than MK262 in a 556.
That would be nice. I wanted a 308 to shoot a deer with. I've done it with just about every caliber but a 308. I have a Springfield NM but my eyes cannot see threw the NM sights anymore. I have single shot and bolt guns. I wanted an semi auto 308 so I bought the HK. Yes it's a tank but it shoots really well. Will take it on this year's hunt but still will be tuff not to take the 300 mag. But then again I'm hunting our farm so having two rifles along won't be an issue.
When it comes to loving my MR762 I'm going WHOLE HOG.
Here's the rail sections at the rear of the M-Lok forend w/an additional QD point, and some M-Lok grip liners I've got @3-6-9 o'clock which give me a more comfortable grip.
Still have to get the Gamma muzzle brake and Hex key bolts for the forend from HK parts.
