HK MR762 Range Day

Ammo: Lake City M80 149gr Ball
Wind: 16 MPH (Gusts over 20MPH)
Range: 200 Yards
Rifle: HK MR762
Scope: Nikon M308
Ejection: 4:00 @ 10 - 12 Feet and very consistent
Clean-up: 10 minutes, but I'm anal so it took me 20

The wind was a lot stronger than I'd have liked on Saturday, which threw me off as it was steady with strong gusts. None of these groups are fantastic and most of them are the result of me or the wind.

I put around 50 rounds total down range on some of the groups overlap to an extent, so I won't post them all. The one's you see below are the worst and the best with the others being somewhere in between.

I took it out again today to the 100 yard range just to verify zero and it performed equally well at that distance. I shot 40 rounds today at the 100 yard line and the smooth recoil made it a pleasure to shoot. The two stage trigger on the MR762 is pretty good, it is no Geissele, but good enough where I don't think I will need an upgrade.

The most remarkable part was how utterly clean the rifle was after shooting 50 rounds of 762 M80 ball. The last two shots are of the bolt face before and after cleaning. I'm fairly certain M80 isn't the cleanest ammo on the planet.

Good results. I don't own one, but have shot a couple. None had any running issues, they shot great with good match ammo and hand loads. One gun had an extended rail that I much prefered, could stretch out a little further. Helped it feel less muzzle heavy.

This is my experience with my MR762 as well. I've put about 30 rounds of bulk 308 147's and then about 40 rounds of FGMM and it's not very dirty at all. Even with an SDN6 on it, it was surprisingly soft shooting.

Very good results for the ammo chosen. Some federal GOLD and I bet they tighten up. Nice rifle.

Very nice rifle indeed! thanks for posting your results.

Nice write up. Thank you. That BCG is a thing of beauty. Picture kind of looks like it has a nickel boron coating.

Why are one of the rounds loaded backwards in the magazine on the table?

Epic sense of humor if you ask me :)

Look up the photos of magazines in some of the old HK pistol ads. Then you will see the humor of rounds loaded backwards, grasshopper. :):D

Those old adds were too funny!

That's an accurate rifle. I may have to buy one for myself.

I "really" wish I had a quarter for every time I have answered this question since 2004/5.

Was it for humor, or the advertisement/promotion departments lack of knowledge on how to load a weapon?

The latter.

H&K is renown for weapons; not for witty repartee, or hip insider jokes.

Yes, Germans are usually quite serious. This was the work of a paid promoter gone wrong.

HKGuns, it looks like a nice, very well made rifle. Good for a DMR role.

Questions:

Is the barrel chromelined or nitrate treated? I realize it's cold hammer forged, but HK's website does not specify about the inner lining of the barrel.

What bothers me is that the gun has no adjustable gas block for suppressed use like my SCAR 17 for example. Have you tried running it suppressed and does the manufacture give any suggestions on what needs to be modified for suppressed use? Buffer weight or spring strength? This issue alone would make me purchase a Knights (which has a longer gas system tuned for use with their suppressors) or an OBR for a "precision" role 16" AR variant. I would bet that the HK would spank those two choices in terms of reliability. I like my SCAR, but it is not a DMR by any means.

The barrel is unlined. I use my762SDN on it without issue. I've shot surplus 308 as well as FGMM, Hornady TAP and M118LR through it without issue with the suppressor.

Humm I seem to remember being told by "experts" here that I would never find a shitty good for nothing piston rifle that shot just over 1MOA. The more I research the more I am a bigger fan of 16inch DMR guns. And yes, all the M80 ball I have shot has been fairly dirty. Did you notice the bore itself being any more difficult to clean than chome lined other guns you own?

As Michael stated, it is not chrome lined, which ticks off the Mil-spec or bust crowd. But it is an HK, the steel they use in the barrel is a trade secret, so "not Milspec" and the alloy used in the other parts is also proprietary and considered a trade secret and thus not "Mil-spec". GASP! That doesn't stop the various military adoptions however......Go figure, I suppose they figure HK understands how to make a rifle.....I tend to agree.

I've not shot the rifle suppressed, sounds like Michael has......

No difference in cleaning, it and my MR556 are two of the easiest rifles in my safe to clean.

When you look down the pipe it is like a mirror finish.

If it ever warms up I'll be throwing some Hornady A-Max hand loads down range which should shoot even better than the M80 ball.

My MR556 will shoot 1/2 inch 5 shot groups at 100 yards with two different loads, after I replaced the factory trigger. I could not ask for better performance from this rifle, it could be lighter, but it is what it is.

I can see the .308 version having a home beside my MR556 in the near future.;)

Figured I'd just update this thread with the latest range data. I had some bud's and kids at the range with me so we only shot at the 100 yard range on New Year's eve.

This is only a three shot group, with the boys and my bud's at the range they were all wanting to shoot this rifle. These are the only three shots I was able to take on this trip. I did some 5.56 shooting instead for the most part.

(Couldn't think of a better way to spend the last day of the year.)

Ammo: 175gr Sierra Matchking
Powder: IMR 4064
Load: 36.3 grains
COAL: 2.80
Wind: 5 MPH
Range: 100 Yards
Rifle: HK MR762
Scope: Nikon M308
Ejection: 4:00 @ 10 - 12 Feet and very consistent
Failures: ZERO

I have not had a malf of any kind with this rifle and I've shot 147 - 150 - 155 and 175 grain bullets.

It appears to shoot the heavier bullets quite well.

Note: I did not do a full work-up on this load to match the rifle, I just picked a mid range load to see how it would perform with these heavier bullets. There is more accuracy here if I were to do a full load work-up.

Not too bad, nice to see someone getting good groups with this rifle. How many rounds have you put through this rifle so far?

Only ~250 or so, it is relatively new.
