Strong Magazine Spring for Umarex T4E HDP50/TP50 Gen1 & Gen2
This tubular magazine spring is a durability-focused upgrade designed for the full-size Umarex T4E HDP/TP50 Gen1 and Gen2. It provides stronger, more consistent follower pressure than the factory-installed spring and is designed to maintain reliable performance during repeated use and sustained compression.
The increased spring force helps heavier rounds feed more securely and consistently through the tubular magazine. It is particularly suited to heavier .50 caliber ammunition such as 8g steel balls, where dependable follower pressure helps support reliable feeding from the first round to the last.

Installation
01
Ensure the marker is safe
Make sure the HDP50 / TP50 is completely
unloaded and depressurized before starting. Remove the CO₂ cartridge and
confirm that no pressure remains in the marker. Then remove the body
retaining pins required to access the internal assembly.
02
Remove the upper assembly
Carefully pull the top slide fully to the rear and lift the upper
assembly away from the body. Keep the assembly controlled while removing it,
as the magazine spring and follower may still be under tension.
03
Install the Stronger Magazine Spring
Carefully remove the original magazine spring
while retaining the factory follower. Install the PRINT-FORCE stronger spring in its place and make sure the spring and follower are correctly seated inside the magazine tube and can move freely without
twisting or binding.
04
Reassemble & Function Check
Reinstall the upper assembly and make sure the magazine spring,
follower and surrounding components are correctly seated before closing the
marker. Reinstall the body retaining pins and perform a basic unloaded
function check to confirm that everything moves freely and operates correctly
before use.

Why Stainless Steel?
Consistent spring tension
Stainless spring steel maintains stable elasticity over repeated compression cycles. This ensures reliable feeding pressure from first round to last without loss of force or “spring fatigue” or rust over time.
Fatigue & corrosion resistance
Designed for high-cycle compression use, stainless spring steel resists permanent deformation and oxidation. This is critical inside tubular magazines where moisture, CO₂ residue, and handling stress are present.
Reliable feed
Precise force control. Too weak can cause misfeeds or inconsistent feeding, while too strong can cause double feeds and increased system stress. This stronger stainless spring is designed for heavier ammo, providing a stable, tuned balance for consistent follower movement and reliable feeding performance.
