re: AR-15 and 300 Blackout

Uhhh, 300blk is expensive to feed. 5.56 is fairly cheap. .300blk is superior in ballistics in terms of energy downrange even though your holdovers will be higher. If money isnt an issue, .300blk is the way to go. For $2000 and .300blk, I would pay the $200 and SBR it. Arsenal Democracy is bouncing back with a new owner. Here is thier pdw in .300blk. A setup like this would look slick. I would say start the build and fill out the form 1 and wait until they come out with the stock (should be 3 or 4 months)
