Attention serious archers! If you're shooting Gold Tip Pierce 400 arrows and want to squeeze every bit of accuracy out of your setup, these ballistic collars are a game-changer. This 12-pack gives you plenty of replacements for multiple arrow builds or to share with your hunting buddies. Here's the technical lowdown: these collars work with your Pierce inserts to reinforce the connection between your arrow and broadhead or field point. But more importantly, they add crucial weight to the front of your arrow, creating a higher front-of-center balance that translates to better flight stability and penetration. We're talking standard 5/16-inch thread that works with most common points, and the increased durability means you won't be replacing damaged inserts after tough shots. Gold Tip doesn't mess around with tolerances - these are precision-engineered to match the quality of their premium arrows. Whether you're target shooting or heading out for hunting season, that extra weight up front makes a noticeable difference in arrow performance. Installation is straightforward if you're familiar with arrow building, and having a dozen means you can standardize your entire quiver. Serious archers know that components matter as much as the arrows themselves, and this is one upgrade that actually delivers measurable improvements where it counts - downrange accuracy and terminal performance.
