The GRS-1 was a snare rifle used by the Gand bounty hunter Zuckuss, among others. It caused no damage on impact but instead fired a shock/stun spray and a liquid spraynet to immobilize the stunned target. Manufactured by Merr-Sonn Munitions, Inc., this weapon required two cartridges to operate; a shockstun mist canister and a liquid spraynet dispenser. The cartridges could fire up to twelve shots before replacement.
