If it isn't stamped "ARP" it is not an AR Performance barrel. Years before most companies knew the 6.8 existed ARP was busy testing different rifling and chamber designs to make sure our 6.8 barrels performed better than any other production barrel on the market. They out perform some so called match barrels at a fraction of the cost.
If you are looking for a factory loaded AR-15 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.
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
This is a complete barrel only, it does NOT include any other parts unless added below as an option.
3R VS 5R- Solid copper bullets like the barnes and Cavity Back bullets may work better in the 3R barrels due to there is 40% less engraving force. You may be able to get more velocity out of the 3R barrels. Using lead core bullets there is no difference in accuracy between the 5R and 3R.
