Overview

Killer Instinct builds this crossbow around a Micro-Lite aluminum barrel, a narrow frame and an adjustable X-Lok foregrip. The six-position buttstock adjusts length, and an integrated Dead Silent Kit reduces noise at the shot.

The pro package covers a scope, rope cocker, string suppressors, quiver, bolts and rail lube, so a hunter needs little else to start. The limitation is the pull weight, which demands real strength or the included cocker, and the specs table disagrees on item weight.

Who it's for

Hunters of a smaller or taller build who want an adjustable stock and a ready package will find it complete. First-time archers should note how heavy the pull is and start with a lower-powered bow.

Pros and cons

Pros
  • Compact adjustable stock
  • Scope and rope cocker included
  • String suppressors included
  • Noise-reducing Dead Silent Kit
Cons
  • Heavy draw weight
  • Weight differs between spec and description
  • Bolts limited to three

Performance notes

Speed and kinetic energy come from the pull weight and power stroke, and the stated speed is a maximum. A light aluminum barrel cuts weight while keeping the barrel stiff for accuracy. String suppressors and the Dead Silent Kit reduce vibration and noise at the shot.
