Recoil Cylinder - 4.7 inch Mark XVIII Mounting

Primary hydraulic buffer that absorbs recoil energy through controlled fluid flow. Contains precisely calibrated orifices that regulate fluid passage during recoil.

Check fluid levels daily, inspect seals monthly

Pneumatic recuperator that stores energy during recoil and releases it during counter-recoil to return the barrel to battery position.

Check gas pressure weekly, inspect for leaks

Transfers recoil force from the barrel to the cylinder fluid. Features a precision-ground, chrome-plated surface for smooth operation and seal longevity.

Inspect for scoring or pitting, lubricate as needed

Prevents fluid and gas leakage at all joints and moving surfaces. Critical for maintaining system pressure and performance.

Replace at scheduled intervals or upon any leakage

Controls hydraulic fluid flow rate during recoil for consistent damping across all firing conditions.

Clean and inspect for wear during overhaul

Secures the recoil cylinder assembly to the gun cradle. Must withstand repeated shock loads from firing.

Check bolt torque and alignment regularly
