These grenades are the most affordable way to launch 60, 72, 84, 96, 108, or 120 bbs at your target with one trigger pull. No more paying for the $70+ BB showers out there. These polymer grenades, while suprisingly affordable, do not sacrifice quality. They are as high quality as the more expensive polymer BB showers out there.
