  • Paul White

    I can’t afford it. I can’t justify it. But I want it. Now to figure out how to make 1600

  • USMC03Vet

    That guy is serious about shooting steel.

    • ostiariusalpha

      He tracked that steel’s spore for 15 miles before he sighted it across the water. You have to use extreme prejudice on those nasty critters too, they’re slow but can lay some real hurt down if one lands a blow on you. Shooting at close range is definitely not recommended.

  • ostiariusalpha

    And do these come with true, honest-to-God Grendel chambers? Not some variant with a 7.62×39 bolt? Also, considering what you’re paying, plus the weight of a UBR stock and full length barrel/forend, you’d think they could give you a slightly more substantial barrel contour than the A2 profile on the Hardcore models. That’s quite possibly my least favorite type of barrel, skinny under the handguard with all the thickness reserved pointlessly for between the gas block & muzzle.

    • Mark

      …and who is making their bolts and magazines (the two chronic Grendel problems)?

      • Wolfgar

        They need to redesign the upper and lower receivers similar to the six 8 LWRCI and the CMMG mutant. Strong bolt and magazine designed for the Grendel and you would have the perfect AR caliber combination.

        • GearHeadTony

          That kind of defeats the purpose of the Grendel cartridge. Grendel was designed to get maximum long range potential out of the existing AR/M4 platform. If you’re going to design a new rifle, you might as well design a new cartridge not constrained by M4 magwells and STANAG magazines.

    They still make 6.8 and 6.5? I thought the latest, must have, will kill everything is the 300 BLK

  • Y K

    I don’t understand why people just don’t think right and stick with 7.62 x 51. Oh that’s right, it’s about selling more crap to us that we don’t need….
