Introducing the Triple Stack system. This new setup features three individually micro-adjustable vertical pins as well as three individually adjustable yardage indicators. Double pin lovers cheered this design, and now we've added third aiming point and additional yardage indicator. The Triple Stack allows archers to set gaps for all three pins, and the adjustable pointers provide constant yardage updates as the dial is turned. The Always Up solar wrap boosts light gathering and ensures solid pin visibility no matter the lighting conditions. Available in .010 and .019 fiber optics and includes all three MRT Rings. This sight is an ideal choice for the archer looking for vertical pin sight but wants multiple pins. Like all Spot Hogg sights, the Triple Stack has Bulletproof pins and is milled from solid 6061 aluminum and is proudly made in the USA.
