Killer Instinct TEMPR-X 405

compact and lightweight 405 fps performance

The Killer Instinct TEMPR-X 405 is a high-performance full-size compound crossbow designed around speed, minimum width and relatively low weight. With a 195 lbs draw weight, speeds up to 405 fps and approximately 134.78 ft-lbs of kinetic energy, the TEMPR-X delivers serious performance while measuring only around 6.75" / 17.1 cm wide when cocked.

At approximately 7.6 lbs / 3.45 kg, it is also relatively lightweight for a compound crossbow in this performance class.

This gives the TEMPR-X a clear purpose: it is particularly attractive to shooters who want to combine 400+ fps performance with an exceptionally narrow and manageable platform.

405 fps with X-Cam technology

The TEMPR-X uses Killer Instinct's synchronized X-Cam system. The cams are designed to efficiently build power while providing approximately 56% let-off during the cocking cycle.

Combined with a 195 lbs draw weight and 13.5" power stroke, the TEMPR-X achieves speeds up to 405 fps and approximately 134.78 ft-lbs of kinetic energy.

The X-Cam configuration also contributes to the compact design and is engineered to reduce vibration and noise.

Exceptionally narrow compound design

One of the primary reasons to choose the TEMPR-X is its narrow width.

The crossbow measures approximately:

• 10.375" / 26.4 cm uncocked
• 6.75" / 17.1 cm cocked

This places the TEMPR-X among the narrowest full-size compound crossbows in its performance class.

The difference matters in practical use. A narrower crossbow is easier to manoeuvre and requires less space for transport and storage than a traditionally wide compound configuration.

Relatively lightweight and easy to handle

The TEMPR-X weighs approximately 7.6 lbs / 3.45 kg, combining its narrow construction with relatively low weight.

This makes it attractive to shooters who consider overall handling as important as maximum bolt speed. Particularly among 400+ fps crossbows, differences in both weight and width can have a noticeable effect when aiming and handling the crossbow.

3.5 lbs trigger and Lumix 4x32 scope

The TEMPR-X features a trigger with a stated pull weight of approximately 3.5 lbs. Anti-Dry Fire protection is also fitted to help prevent the crossbow from being fired without a correctly loaded bolt.

The package includes Killer Instinct's Lumix 4x32 scope and two premium 20" 390-grain HYPR crossbow bolts, providing a well-equipped performance package.

Rope cocker as standard, optional crank upgrade

The TEMPR-X is supplied with a sled rope cocker. This reduces the effort required to cock the crossbow and helps draw the string back evenly.

The crossbow is also compatible with the optional Killer Instinct Compact DSC Narrow 1.5 crank cocking system. Shooters who want greater cocking assistance later can therefore upgrade the platform.

This also creates an important distinction from a model such as the EK Archery Vulcan 415 Silent Crank: on the TEMPR-X the crank is an optional upgrade, whereas the Vulcan 415 has its crank system integrated as standard.

Who is the TEMPR-X 405 for?

Within our crossbow selection profiles, the Killer Instinct TEMPR-X 405 is particularly well suited to Performance & Power, Compact & Mobile and Precision & Distance. Its optional crank upgrade also makes it relevant to Upgrade & Progress.

The TEMPR-X is particularly suitable for shooters who:

• want 400+ fps performance;
• prioritise an exceptionally narrow full-size compound design;
• value relatively low weight;
• prefer the Killer Instinct brand and ecosystem;
• appreciate a light 3.5 lbs trigger;
• want the option of adding a crank cocking system later;
• want a complete package with Lumix optics and HYPR bolts.

Shooters who prefer a more traditional and wider compound configuration can consider the Killer Instinct Lethal 405 HD.

Those who place greater emphasis on maximum cocking assistance than minimum width and weight may prefer the EK Archery Vulcan 415 Silent Crank with its integrated cocking system.

The TEMPR-X therefore stands out through its combination of 405 fps performance, exceptional narrowness, relatively low weight and Killer Instinct X-Cam technology.
