Helpful Positive Review Boss 405 killer instinct by Kheb, December 21, 2023
Great price, and shipped faster than expected, but problem with the crank cocker that came as an add on, as it wasn’t compatible for the model of crossbow, sent that one back and received the correct crank. Otherwise happy with everything.

Helpful Negative Review Piece of junk by Dave K, Verified Owner, March 27, 2025
1st of all the scope had something inside obstructing the view. 2nd, the string / cable snapped when sighting it in. Killer Instinct would not repair under warranty. I’ve shot this only a few times and only one day.

Product Info for Killer Instinct Boss 405 Crossbow Kit

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.image
