I wrote a little while back in my interest in Straight Jacket barrels made by Dracos. They are pretty expensive, which has kept me from trying them for some time.
For this Black Friday, they are giving a crazy discount on their AR-10 barrels in 243Win, 260Rem and 7-08. $250 for a new barrel and $150 for a blemished (cosmetic). Normally, these are $850 and $510 respectively. If you are a reloader and want to try one of these barrels, this is an awesome opportunity.
