So Im looking to do a budget build for an ar-15 upper. And I missed the group buy. So Im on green mountain rifle and I can't figure out the difference in these barrels.
Other than 1:8 twist vs 1:9 but why the $50 price difference? The $100 has a parkerized finish and the $150 doesnt say. Is it just a sale? Im not an expert on barrels. Thank you for your help

$99 is GM-M9 / $149 is GM-M8
