The 6mm ARC is a brand new cartridge that Hornady designed to fit into a standard AR-15. ARC stands for “Advanced Rifle Cartridge.” The caliber is 6mm or .243. The cartridge is specifically designed to maximize performance in AR-15s with barrels between 12 and 24 inches. <\/p>\n\n\n\n

If you have an AR-15 all you need to convert over is a new barrel, bolt head, and magazine.\u00a0<\/p>\n\n\n\n

Currently, the most popular selling long-range cartridge in America is Hornady\u2019s 6.5 Creedmoor. Because of how Hornady designed the cartridge and chamber, the 6.5 Creedmoor is exceptionally accurate as long as the rifle manufacturer follows the chamber blueprints that Hornady designed, which most do. Unfortunately, 6.5 Creedmoor is too big to fit into America\u2019s rifle, the AR-15. <\/p>\n\n\n\n\n\n\n\n

<\/p>\n\n\n\n

So, Hornady has stepped up and has done the same thing in designing the 6mm ARC that they did in designing the 6.5 Creedmoor. They designed the chamber and cartridge upfront to maximize efficiency and long-range accuracy.  It\u2019s optimized to shoot heavy bullets with high BCs<\/a>. Hornady recommends a fast 1-7.5 twist barrel to stabilize the heavier bullets. <\/p>\n\n\n\n

To test the 6mm ARC we installed ODIN Works 6mm ARC stainless steel barrels into the upper receivers. We tested an 18-inch barrel and a 21-inch barrel. The barrels use a rifle length plus (+) 2-inch gas system. We had an ODIN Works tunable gas block on the 18-inch barrel and an ODIN Works adjustable gas block on the 21-inch barrel. We were extremely limited on ammo so we shot one group out of each gun to get a rough zero and chronograph. Based on what I\u2019ve seen thus far and considering that we did no barrel break-in they shot darn good!  (We’ll get more ammo and do a complete review in the near future.) <\/p>\n\n\n\n

Using the 21-inch barreled rifle, I went 8 for 8 on a 12-inch-round plate at 708 yards in about 20 seconds with wind. Watch the video to see the recoil or lack thereof, actually. <\/p>\n\n\n\n

ODIN Works will be initially offering the barrels in the following configurations:<\/p>\n\n\n\n
