  1. Met these guys at Shot Show last year and was really impressed with them. Glad to see the latest offering.

  2. So comments are completely off for the sponsored articles? Nice, uncle Stalin would be proud.
    So I guess I will post it here then. LMAO!
    350$ for 100 rounds through a minigun? What a rip-off. You can buy a 1000 rounds for that kind of money, take it to a machine gun shoot at Knob Creek, Big Sandy or any other, give half to the gun owner and he’ll be happy to let you run the other 500. It will probably closer to you and easier to get to as well, than middle of nowhere in South-West Texas cartel country. 🙂

    • Then you can get a facility, an SOT, a staff, and a marketing department and then undercut their prices. And then buy all the replacement parts on a gun with that kind of round count. And pay taxes, and insurance, and a lease, and them post your P&L statement.

    • I was on the big Sandy website yesterday, and they charge lots of money to fire the MG rentals as a spectator (4.00 per round of .50, 35.00 for 20 rounds on the other ones (they provide the ammo)), and it’s against the rules for you to shoot the machine guns that the shooters who purchase a spot bring (Shooters may not let spectators shoot their guns for insurance reasons.”

  3. I wonder what DERP thinks about these US made optics? Come on DERP, enlighten up with one of your insightful comments.

    • Nothing DERP? Why, this is the most insightful input you’ve had in any TTAG comment section.
      Because whenever you post, it’s nothing but BS.

  4. What are the good brands or product lines for sub-$1000 rifle scopes that are made in the US (or at least a country freer than China)?

      • Burris is owned by Berretta and makes most of their optics in the Philippines. The are good, rugged scopes, just not with the same level of glass as the better US Optics and Leupolds. I know my Burris handgun scope is ok and all, but nowhere near the quality of my Leupold handgun scopes.
        Leupold is great, and with the “light management” filtering on the scopes of the last few years, they are my go-to brand for optics. However, the ones in the same category as these US Optics cost much more than $1K.

    • Burris XTR and XTR II are made in the US, but not quite as good quality optically. Leupold Mark 6 are pretty close, but also at a similar price point.

      • Kind of. They are, according to their initial press release on the II and III, “designed, engineered, and assembled in the USA,…”

        I’m taking that to mean the parts are made in the Philippines and assembled and QC’d here. Which is pretty good for the money.

  5. Vortex has unfortunately moved some their optics from Philippines and Japan to China. Even their top end Razor binoculars are Chinese made.
