Which barrel should one take a chance on being most accurate with 147gr. through 168gr., possibly heavier projectiles? A&D?, the recent Portugese imports? or the RCM offerings?
Is there anyone in particular who is known to put together railed receiver G3 type rifles well enough to function as a DMR given quality parts?
if A&D you are referring to is Albert & Duval the only source would have been hk as far as I have seen. They supplied hk with their cannon barrel steel which either they or hk hammer forged and to quote hk they performed “other“ non disclosed ”special steps“ in production. I wonder if they cyro treated all the parts?
look at A&D’s website and you will see a scientific grade metal producer. Nato cannons. Real technology.
As far as info available no other maker used that kind of steel. I think the whole Austrian gun is A&D sourced metals. Even trigger parts.
”you cannot wear out a hk91/g-3” is the result in my experience
if I were to build a DMR hk 91 type rifle again I would start out with a used 91 and replace the barrel. And source as good of a trigger as possible.
the original JLD built PTR’s used Wilson barrels and were noted for high accuracy. Not perfect quality control was posted.
recently I purchased two in the white hk 91 type barrels that seem to be late model hk products. They have a step in the end of the barrels machining which normally would alter the barrels harmonics.
‘There have been several 911’s sold on gun broker recently with PSGI trigger groups. The barrel shroud turns off without damage as the weld was faked from hk. I in 11’ twist and 7.62x51 chambering results in a sub MOA hk factory steel rifle that easily fits a DMR role with handloads or FGMM ammo.
no cheap way to do this. I acquired spare hk barrels long ago and two in the white new ones recently just to be able to build up another one or two. ]
the Mexican army when we dirtbiked there in 2000 had 1960’s g-3’s that had had their entire finish worn off them. Shiny steel. Every inch. The officer said they shot as well as they did new. No service ever. WTS had thousands of the Mexican trigger groups sent to him for service. A handful of springs. Zero defects or wear. He was amazed. But not suprised.
‘here is my 911 with a set trigger and reloads 30+ years ago on a slight wind afternoon. I put the rifle away. Done
