-If you are looking for a factory loaded AR  cartridge to hunt yotes, deer and hogs the 6.8 can't be beat in terminal performance. The exterior ballistics of the 6.8 and Grendel are within a few inches of each other all the way to 400yds. The 6.8 starts off 80-100fps faster with the same weight bullet and barrel length. The 6.8 has a great selection of usable hunting bullets. A 5.56 and a 6.8 could handle every possible need.

These 18" barrels are a great compromise and choice between the 16 and 20".  They aren't much heavier than the 16" and are 40-50fps faster.

Hi perf. chamber and barrel allow for ANY factory ammo to be used along with the hottest handloads. The throat/freebore is designed to be more accurate with a wider range of bullets than the typical SPCII chamber.
DO NOT USE bullets that measure over .277" in these 6.8 barrels they will cause excessive pressure

    DO NOT USE  bullets that are larger than .277" in these 6.8 barrels, the chambers were designed for .277" bullets and all 6.8 barrels have a .277" bore so bullets larger than .277 will cause excess pressure and increased copper fouling.  It seems some Maker bullets and Cavity Back bullets made by Maker are .278" and on top of that they are solid copper so check the diameter of the bullets before using them.
