Looking at a possible purchase of a 300 blackout barrel at a local gunshow. Guy wants to sell a new complete upper, minus the bolt, 350 loaded rounds (j-word things), and will throw in a laser rangefinder, either a Bushnell or a Nikon 600 yard. He is asking $450.00 for the barrel, or $700.00 for the set. He seems like a motivated seller, so possibly talk him down more, or throw some more swag in.
Couple of questions: 1. Not knowing the barrel manufacturer, what should I be looking for.
2. Would this be a good buy. 3. How hard is it to set up for this round. I already have several 30 cal. molds, but not dies. Not really looking for subsonic loads, just a good all around plinker/heavier round for the AR platform.
Thanks in advance.
