The Auto-Lock Difference: they lock closed and lock open!
The Auto-Lock is engineered to stay locked closed on launching and in flight. The blades lock under the ferrule and are held in place by a reliable stainless-steel spring (not a rubber band).
The torque produced by a 400+ fps crossbow will not cause the blades to open.
Available in 100grn, and features a 1.7" cut diameter for huge holes and great blood trails!
