Barrel nut/delta ring
Could not find this doing a search but is the barrel nut and delta ring found on an AR15 chambered in 5.56 the same on a 6.8spc? I am assuming so since i have heard you can upgrade your AR to 6.8 with a simple barrel swap but i dont like assuming and want to be sure.
"If you love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsel nor your arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that you were our countrymen"
-Samuel Adams, 1776
