I just picked up my Lawton and Stiller receivers the other day and now I need to come up with triggers. The Lawton is a SA 7000 and will be a 6X47Lapua, set up to be a coyote rifle. The Stiller is a Tac30 and will be a 223AI, set up to be a varmint rifle. Any suggestions on what triggers are good for these setups? Any to stay away from? Thanks
