Heckler & Koch MR308 review

$3995 where I work.

Ouch.

You can get info on alloy performance by this, but it is not so easy to reverse engineering alloy manufacturing process.

Easy, definitely no. But totally possible.

One needs an accurate chemical analysis, from that is possible to establish the proper alloy steel. This is easy and cheap.

From metallography, the crystal structure might point to the heat treatment. This is easy and cheap.

A long, laborious process of trial and error, that only but a few devoted individuals/companies would pursue. This is expensive.

My godfather, who is an accomplished metallurgist, once said that all "special secret metals" only last a few hours in a lab.

Alloy, CHF, non-CL. Probably nitrided, but HK keeps mouth shut on what they do their barrels. Took them 6 or 8 years to admit nitriding pistol barrels. Alloy specification used is also HK secret (there are rumours or assumptions, but no 100% info).

Does nitrided treatment have any of the lubricity properties of chroming?

It is better. There is lot of topic on it here on M4C.

Just checked the groups with the Sako Range 123 gr ammunition, c. 17-23 mm at 100 meters with the 16" HK417.

So might be something to trial with the U.S. MR762's as well, however I do not know if it is available there?

I think these are realistic figures for the gun I have here too. With proper rest, better scope and warmer conditions (and maybe a better shooter too!) the groups would have been quite a bit smaller. Red donut of death and the 3,5x magnification on the ACOG doesn't really make it a good scope for shooting very tight groups.

What I think my test achieved is the minimum attainable accuracy with that setup. I think the gun is sub-MOA by marking. Might be close to 1/2 MOA very well, just like Tuukka's gun.

So its a little cheaper than a SR-25 and way more than a Larue or a LMT 308

The big question is it worth the price?

Doesn't use common mags and its a piston gun, hmmm

Ouch.

Looks like a nice rifle, thanks for posting your thoughts. Wouldn't mind having one, but the price is too steep for me.

AR10 types rifles don't have a common magazine anyways. As long as it's reliable, a piston shouldn't be a detractor I think.
