CORE Rifle Systems Now Making Ammo

CORE Rifle Systems, the company whose motto is “Where MIL-SPEC is just a starting point” has decided to expand their product line to including ammunition. In addition to their line of rifles and components for the commercial market, CORE has a law enforcement line of SBRs and post-sample full-auto firearms. It should be interesting to see how their ammo performs. As you can see below they’ve launched the line with a combination of .223 Rem and .300 BLK, and with its own motto: “Fire for effect.”


From CORE:

“As CORE Rifle Systems progressed with its own vertical integration, culminating in the manufacture of our own precision barrels, we saw the need to bring the final piece of the accuracy puzzle under our control. Enter CORE Ordnance. By combining the finest components available in closely controlled, small-batch “boutique” grade ammunition, we have closed the loop in attaining perfectly repeatable accuracy and unquestioned terminal performance in a fully integrated long gun system. Whether your day involves punching holes in paper, reducing the local varmint population or anchoring an angry hog at close range, CORE Ordnance by CORE Rifle Systems has you covered. CORE Rifle System’s is currently testing 3 new .308 rounds. Stay tuned for more information on these and all other new product developments at

 Utilizing the finest projectiles available from today’s top manufacturers, including Sierra Matchking, Hornady, Nosler and Lehigh Defense, and combining that with high quality Hogdon H110 powder, we have given shooters wide variety of loads to choose from. Our 300 BLK ammunition is loaded from once fired Lake City 5.56 brass and our .223 is newly manufactured brass. CORE® Ordnance offers these great selections:

    The pictured 300BLK subsonic will not load in a standard STANAG magazine. That 208Gr Amax is seated waaaaay too far out…. Hopefully this is just a shoddy marketing pic and not the actual product. I’m all for new loadings coming to market, especially 300BLK, so long as they work.

  • Tater

    With a slogan like “where MIL-SPEC is just a starting point” why are they selling .223 spec ammo?

    • Giolli Joker

      If the specification only defines a minimum requirement, everything that substantially exceeds that requirement is still in specification, although likely with better performance over the ones that barely pass said requirement.

      • Tater

        .223 rem is lower pressure than 5.56. It has uncrimped primers and unsealed case necks. It’s LESS than MIL-SPEC. None of their rifles that I’ve seen have been up to spec (improperly or un stalked carrier keys and castle nuts, unlined 1in9 barrels) so I’m not surprised that their ammo isn’t.

  • Aklover

    After stocking CORE rifles for a minute and seeing how well those worked out, I wouldn’t touch ammo by then with a 10 foot pole.
