A deadly combination of high-octane fire power and agility, the BOSS™ hits targets hard at 405 feet per second. The 6-position AR-style buttstock shortens the crossbows overall length for smaller frame hunters but extends comfortably to fit a variety of medium to taller shooters as well. The dependability and tack driving accuracy Killer Instinct is known for is produced by a new Micro-Lite aluminum barrel that eliminates excess weight while still producing dead-on accuracy. The new X-Lok adjustable foregrip and easy-to-handle narrow frame produces a balanced and compact shooting machine. Finished off with a noise reducing integrated Dead Silent Kit, the Boss 405 is sure to produce deadly results.

Why Equalizing the Weight of Non-Lighted Arrows is Important

When choosing Firenock lighted nocks you have an option use the weight match nock system.

There is roughly a 23 grain difference when adding Firenock lighted nocks. It can result in lower impacted points at distances of 30 yards and beyond, and also change your front of center percentages.

There is a simulated weight that attaches to your nock just the same as the lighted nock that will make all of the nocks weigh the same. This will ensure your arrows all fly the same.
