AR10 MATCH RIFLE 008



THE GUNSMITH
  • John Holliger
  • THE SIGHTS
  • None furnished, not sure what kind of scope the customer mounted.


  • THE CALIBER
  • Chamber is .308 Obermeyer. The old standby that seems to always shoot good. Slightly longer than the 95 palma reamer.
  • THE BARREL
  • Krieger 1-10. Contour is .840 under then handguards and then .740 from the manifold to the muzzle. Length is 22". Manifold is moved 3" forward of original location and with this short amount of barrel past the manifold it needed a .096 port to cycle, but functions great and is very easy on brass with hardly any extractor marks.


  • THE TRIGGER
  • Early Krieger-Milazzo.
  • THE FURNITURE
  • BUTTSTOCK: OEM
  • GRIP: Sierra Precision
  • FOREND: Holliger designed carbon fiber free float tube
  • HANDSTOP: Swivel stud for bipod
  • MANIFOLD: DPMS


  • THE STORY
  • This was a fun project. I have a customer who has another AR-10 that I built and he loves using it to hunt deer in WI, but doesn't like the weight. This was an attempt to make an AR-10 as light as we could without resorting to drastic measures like skeletonizing the carrier or stuff like that. Our goal was a good shooting AR-10 in .308 that would weigh under 10 pounds complete with scope.

    Due to the intended use of this upper there is no handstop rail, but it does have a swivel stud for mounting a bipod. Gas manifold is a DPMS. (hope to have my own soon, DPMS doubled the price on there's)

    Forend is .062 thick carbon fiber tube, 2" diameter. It has aluminum reinforcement for the sling swivel, and a black anodized aluminum end cap to give it a finished look.

    This is the kind of project a gunsmith likes because it lets us get a little creative. This forend tube was actually the prototype of what I hope will be a standard offering for WOA.


  • THE RESULTS
  • Loads - I tested the upper with Federal gold medal 155 palma ammo. The following is from an e-mail from the owner:

    "I shot the new upper over the weekend. My first 5-shot group went into 0.8 inches. This was the 175 Sierra Matchking with 44.4 grains of Varget. I'm very pleased with the upper"
