Steel Firing Bolt – Professional Upgrade for HDP.50

This standalone Firing Bolt represents an ideal solution for anyone looking to increase the reliability of their Umarex HDP.50 weapon. Unlike standard parts, this bolt is made of solid steel with precision black polishing. The main benefit is the optimization of internal cycling and improved propellant gas flow through the valve, leading to a more stable muzzle velocity and higher durability during demanding use.

Thanks to the polished surface, there is a significant reduction in friction inside the weapon, which not only increases the reliability of every shot but also protects other internal components from excessive wear. Thanks to precise dimensions, "drop-in" installation is very easy and does not require permanent modifications to your pistol. it is an essential accessory for tactical training and recreational shooting.

Frequently Asked Questions (FAQ):

1. Does this part fit the older GEN1 version?
Yes, this Firing Bolt is fully compatible with both the Umarex HDP.50 GEN1 model and the newer GEN2 version, as the internal firing mechanism remained identical in both generations.

2. What is the difference between this and the original part?
The main difference is in the material used and the surface finish. Our steel version is much more resistant to deformation, and the polished surface ensures smoother operation inside the weapon.

3. Is it necessary to grind anything during installation?
No, the Firing Bolt is manufactured with high precision as a direct replacement for the original part. We only recommend regular lubrication with silicone oil to ensure maximum lifespan.
