What the E-19 Hop-Up Bucking does
What it does
The hop-up bucking is the rubber sleeve at the back of the inner barrel. It seals around each BB and puts backspin on it, so the BB flies flatter and farther.
When to replace it
- Accuracy has dropped or BBs curve off line
- BBs jam or double-feed at the chamber
- The rubber is torn, worn or hardened
Often replaced together
Small parts wear together. Order them in one go and save a second wait.
