Bio BBs only. 400 fps max with .20, good attitude, no bang bang rule, no surrender rule. We do have refs or myself doing integrity checks. Friendly fire still counts. Smoke grenades need to be approved before you use them. Thunder B's are ok to use. No full auto inside buildings. Flashlights can be used but no lasers. Full face protection for anybody under 18, sealed eye protection. No mesh goggles. Barrel cover and dead rag needed. We have both at the park if you need them.
