Many people write to me and ask how I am able to squeeze the trigger with no finger movement. It's simple and inexpensive using the BMF activator from Cabelas . I do not squeeze the trigger I just pull back the crank with my wrist and it fires my crossbow, shotgun or rifle.
The trigger activator can work for a right or left-handed shooter, installs in minutes using two screws. I have one on everything I shoot just to make it easier.
You could just purchase one and move it from crossbow to shotgun to rifle in a matter of minutes. Good luck with your season and don't forget to send in your harvest pictures.
