Tactical repeating crossbow EK Archery Cobra RX Adder: the latest in weapon technology!

This is the most fun of all crossbows available on the market! It is able to shoot 5 bolts in less than 30 seconds, it is very easy to arm and maintain! Since the release of the Cobra R9 crossbow the world of crossbow making has been shaking up by innovations that make cocking easier, and the Cobra RX Adder adds another level with its automatic loader! Its design is devastating and it comes with many accessories. If you want a leisure crossbow then this is the one for you! With it, you can easily imagine yourself shooting at several targets in the garden, a bit like a course with enemies to target and shoot as quickly as possible.

The Adder mechanism cannot be purchased alone to be installed on the Cobra R9 or RX as the RX Adder has a modified trigger system to accept the Adder system. It is the first magazine crossbow sold in the trade!

The Cobra R9 crossbow was already easy to cocking with its innovative cocking lever, the Cobra RX crossbow is even more advanced with its new 130 lbs bow and the Cobra RX Adder crossbow combines both with the addition of a 5 bolt automatic loader! It is also equipped with an adjustable AR-type stock that ensures a good shoulder hold and a comfortable shooting position for even more accuracy.

The attachment rails for accessories are 21 mm rails.

Our recommendations for the Cobra RX Adder crossbow:

The Adder mechanism cannot be purchased alone to be installed on the Cobra R9 or RX.

    L'arbalète est super, le chargeur c'est un must ça change tout. Les vidéos d'Hattila sont très utiles. Par contre, il a du jeu dans la crosse, mais ce n'est pas un secret sur ce modèle c'est hélas un problème.
