Steel Firing Bolt – Professional Upgrade for HDR.68

This standalone steel Firing Bolt represents a top-tier enhancement for every owner of an Umarex HDR.68 weapon. For a revolver of this caliber, enormous emphasis is placed on the strength of internal parts. Our Firing Bolt is made of high-strength steel followed by black polishing, ensuring its uncompromising durability even when using maximum allowed power.

The main benefit is a significant reduction in friction within the weapon's firing mechanism. This ensures not only more consistent performance but also protects the valve system from premature wear. Thanks to precise dimensions, "drop-in" installation (direct replacement) is very easy and requires no irreversible modifications to the revolver. It is an ideal choice for those who use the HDR.68 for intensive training or self-defense purposes.
