Here is a AR-10 You might find interesting, notice it has 2 pistol grips, the one in the back is a small electric drill clamped to the stock, then 2 bolts go to a bridge across the trigger, the drill is turned on by a bite switch, made from a electric car antenna, when you bite down on the red tip, it fires the rifle.

We made this up for a disabled vet that lost both arms at the shoulder, we put a scarf around the stock and his neck so he could wiggle his head around look threw the scope, when he got it all figured he could hit a 2" bull at 100 yrds every shot,if he didn't bite to hard and get a double tap, we set him up in a deer blind, and he shot a nice management buck, at about 150 yrds, he got a little excited and double tapped him, DRT. I backed him up, in case it didn't work but he didn't need my help. Rio7
