Perforated Models
Perforated models are approximately 1.375 inches in length. The top caps are cross drilled with a 7/32" hole to accommodate a stainless steel or brass split ring. The bottom is center drilled to create a vertical shaft to house the included v10 glow powder vial or a 3x23mm tritium vial (not included). The barrel has been drilled in a random pattern with various sized holes that range in diameter from 1/16" to 1/8" to allow the glow rod to be exposed.
