Description

The 4005040501 Bolt Complete is a critical internal component for Steyr’s high-precision match air pistols. This assembly includes the loading probe, the bolt body, and necessary mounting fixtures required to replace the entire cycling mechanism.

Designed to ensure a perfect breech seal, this bolt is vital for maintaining the high-pressure efficiency of the LP 10 and EVO 10 platforms. Over time, the internal seals on the pellet probe can wear down, leading to air loss at the breech and inconsistent muzzle velocity. Replacing the “Bolt Complete” assembly is the professional solution to restore the pistol to factory-spec airtight performance, eliminating the need to source and install individual O-rings or springs separately. It is available in both black and silver finishes to match your pistol’s specific aesthetic.
