ARM USA is having a .50 shoot on the 31st at Angeles Range and should have about 7 or 8 .50's set up. All you need to do is pay the range fees, walk down to the end of the rifle range and pay $5 a round to shoot whatever .50 you want.
Some of the SoCal 50 Shooters group should be there also, great bunch of guys. When you get your .50 and want to shoot with us, we shoot there the 3rd Sunday of every month. Not that you need a .50 to come out and shoot with us.
