no there is not. so i cant preload to fullest value. however, with out a front stop the carpet on top of the bench hardly allows any forward pressure before i loose traction. it feels like i am chassing this thing down the range. I am hoping and moving, and having to re-setup each shot. NOT GOOD. i was looking at some cleated feet. i am sure they would bite into the carpet, but i assume it wont slide back. maybe good or bad?
