HEAT CORE BOLT BUMPER Seal for Valken Milsig M17 Gas Markers - 3 pcs

HEAT CORE BOLT BUMPER Seal | Reinforced Bolt Stop for Valken Milsig M17

The HEAT CORE BOLT BUMPER seal by HOMEDEFENCE-24 is specifically designed for Valken Milsig M17 gas markers. It is a robust replacement for the original seal that significantly improves shooting performance and consistency.

With a thickness of 3 mm, this seal is many times more robust than the original. This allows the bolt to be braked more gently, effectively preventing double feeding (a "double shot") when using higher pressure. Furthermore, due to its thickness, only 1 piece of the seal is needed instead of 3 or 4 standard pieces. The seal is made of highly durable two-component industrial silicone, which guarantees a long lifespan.

Key Features and Specifications:

  • Intended for: Valken Milsig M17 gas markers.
  • Function: Gentler bolt braking, prevention of double feeding.
  • Material: 2-component industrial silicone.
  • Thickness: 3 mm.
  • Shore Hardness: A26.
  • Tensile Strength: 500%.
  • Temperature Resistance: Up to 250 °C.
  • Maximum Pressure: Tested up to 2000 PSI HPA tank output pressure.

rprshop recommends this upgrade for every Valken M17 owner looking to increase the reliability of their marker and ensure stable performance at higher pressures.
