I just put together a .300 BLACKOUT AR-15. I had an Aimpoint in the tool box so I put it on. I still need to change out the front hand guard and stock. I will also need a sling. My plans are to make my own ammo for it. Any advice would be great. I plan to shoot max 300 yard most of the time under 200 yards.
New .300 Blackout any tips for me?-300-blackout.jpg
