5.56 to 300BLK AR

TriggerologyTuesdayTip for new AR owners:
You can use your 5.56/.223 AR15 style rifle’s lower receiver portion to shoot 300 BLACKOUT. Just acquire a 300 BLACKOUT upper receiver, some ammo, mags (you can use most 5.56 magazines, just mark them so you don’t mixup ammo) and essentially you got yourself a new #freedomseeds dispenser!
