What the E-16 Main Seal does
What it does
The main seal is a rubber seal in the gas path. It keeps gas pressure where it belongs, so every shot gets full compression.
Seals wear with use. Replacing a worn one is one of the cheapest ways to bring back lost FPS.
When to replace it
- FPS has dropped or shots feel weak
- Gas leaks while firing
- The seal looks torn, flattened or dried out
Often replaced together
Small parts wear together. Order them in one go and save a second wait.
