this is tricky first try MyOpticsPro.com second make sure the gun is sighted in befor he heads to the woods and wounds a deer ,what brand of gun is it?i'd be leary of hunting with a "crappy"gun.red dots are good for quick target pickup and arent as good as a reticle scope IMHO,nikon makes a good slugun scope ,you also need rings,mounts.those cantalever shotgun mounts are supposed to take the recoil well
Now therefore take, I pray thee, thy weapons, thy quiver and thy bow, and go out to the field, and take me some venison.
Genesis 27:3 "The thinking deer hunter should mature through three phases during his hunting life. First phase, "I need to kill a deer." Second phase, I want to harvest a nice deer. And last phase, we must manage this resource so our children and their children can experience the grand tradition of good deer hunting." - Jim Slinsky
