High-Performance Carbon Bolts Designed for the Cobra System RX Adder Magazine System
The EK Archery Cobra Adder 7.5" (19 cm) Carbon Bolts are precision-engineered specifically for use with
the Cobra System RX Adder magazine-fed crossbow system.
Correct bolt dimensions, stiffness, and weight are essential for smooth feeding and safe operation.
Note: Using non-compatible bolts may lead to malfunctions such as feeding issues or bolts becoming stuck in the magazine.
Premium Carbon Construction
Crafted from 100% tough carbon fiber, these compact bolts deliver outstanding performance:
- Ultra-slim outer diameter for improved ballistic efficiency
- Maximum shaft rigidity for flatter trajectory and superior speed
- Smooth low-friction surface for easier target removal
- High durability with consistent straightness, ensuring stable flight characteristics
Despite their small size, these bolts maintain excellent structural integrity and consistency—
ideal for semi-automatic magazine crossbows.
Precision Nock & Fletching
- Benchmark half-moon nocks provide perfect string alignment and positive string-to-bolt contact
- Hand-fletched vanes deliver strong downrange accuracy and tight grouping
These features ensure reliable cycling in the Adder magazine and consistent performance shot after shot.
Removable Tip
Each bolt includes a removable field tip that is compatible with the designated Adder high-penetration tip.
