Retiredarmy, welcome to the forum. i am retired Army also. Be sure to wax the string seizing very often,about every 10 shots. Take the bow down once inawhile and really coat the cables with wax where they cross inthe slot. Some of the seizing can only be waxed when the bow is cocked. The Quad 400 is a very powerful crossbow. Wish you well with your new crossbow.

Oops,wax the track about every 5 shots.
