Ek-Archery Heavy carbon crossbow bolt for Cobra System ADDER TX, 7.5", 1 pc

The heavier Ek-Archery carbon bolt is specially designed for Cobra System ADDER TX crossbows and is also compatible with Cobra R9, RX, ADDER, and Upgrade ADDER 180 lbs versions.

This bolt features a higher weight and is therefore specifically intended for more powerful Cobra System ADDER variants such as the compound ADDER TX or the Upgrade ADDER equipped with a 180 lbs limb.

High-performance carbon bolts designed for the Cobra System RX ADDER magazine-fed system

The heavy EK Archery Cobra System Adder TX 7.5" (19.05 cm) carbon bolts are precisely engineered specifically for use with the Cobra System RX ADDER repeating crossbow.

The correct bolt dimensions, stiffness, and weight are essential for smooth feeding and safe operation.
Note: Using incompatible bolts may lead to malfunctions such as feeding issues or bolts jamming inside the magazine.

Premium carbon construction

Made from 100 % durable carbon fiber, these compact bolts deliver outstanding performance:

• Ultra-slim outer diameter for improved ballistic efficiency
• Maximum shaft stiffness for a flatter trajectory and higher speed
• Smooth low-friction surface for easier target removal
• High durability and consistent straightness for stable flight characteristics

Bolt weight: 240 gr (±5) = 15.23 – 15.9 grams

Despite their compact dimensions, these bolts maintain excellent strength and consistency — ideal for repeating magazine-fed crossbows.

Precision nock and vanes

• Half-moon nocks ensure perfect string alignment and reliable contact
• Hand-glued vanes provide high accuracy and tight groupings

These features ensure reliable feeding in the Adder magazine system and consistent performance with every shot.

Replaceable tip

Each bolt is equipped with a removable field tip compatible with the special high-penetration tip designed for the Adder system.
