What You Get
A 2 ¾ by 5 1/8 inch 2-piece cardboard card wrapped in clear plastic containing a small Ziploc bag with Instructions and another card with a small plastic bag holding 20 barrels taped to the card (Figure 1). For no blast bag mounts (-058), each barrel is 7mm long with a 1mm tab at the end. For mounts with blast bags, each barrel is 4.5mm long with a 1mm tab at the end (Figure 2). The tip has a fine hole that is difficult to see, but it’s there.
