The crossbow of the future – a gamechanger pushing the limits of versatility.
A unique model that allows shooting .68 caliber balls while also offering the option to convert back to shooting arrows.

Basic description

• B08 Upper with a magazine for 8 projectiles cal. .68

The crossbow is designed for recreational shooting, training, and paintball.

The crossbow works like other AR-series models – by pressing a button, you can tilt the Upper and insert the limb. Thanks to the quick-release system, the crossbow is ready to shoot within seconds and allows rapid firing of 8 shots in a row.

You can use all standard .68 caliber balls:

✔ paintball balls

Safety and use

When using a 35 lbs limb and soft or breakable balls:

• suitable for indoor use
• suitable for paintball

Important: Always wear eye protection – goggles, mask, or helmet.

• the included ammunition is not soft enough and may cause injury
• the included glasses are not suitable for paintball, may slip off, and do not provide sufficient protection

Warnings – performance and risk

When using stronger limbs and harder or heavier projectiles:

• the crossbow is not suitable for shooting at players
• use is at your own risk
• the manufacturer is not liable for injuries or property damage
• it can be as dangerous as a crossbow shooting arrows
• steel projectiles may cause dangerous ricochets

Ricocheted projectiles can, even at distances of hundreds of meters, cause:

• serious injury
• property damage
• or death

Technical warnings

• when using strong limbs, use sufficiently heavy projectiles
• projectiles that are too light may:
  • cause increased wear of the string
  • damage the feeder (slider)

Feeder (slider)

The crossbow features a patented feeder that:

• gently accelerates the projectile
• allows shooting balls filled with liquid or powder without damaging them

The feeder is available as a spare part.

Use for self-defense

The manufacturer recommends balls with an irritant filling (PepperBalls™), referred to as “Less than Lethal” (with a very low probability of causing death).

Warning: When using hard or heavy projectiles, the crossbow becomes potentially lethal and must be handled accordingly.

Important: When choosing .68 caliber ammunition, comply with the legislation applicable in your country. Some projectiles may be subject to restrictions.

Maintenance

• regularly wax the string with high-quality wax
• lubricate the rail with a suitable lubricant

Regular maintenance will significantly extend the lifespan of the crossbow.
