Flexzilla Lock-N-Load Variable Stroke Pistol Grease Gun L1075L$47.54
LOCK-N-LOAD technology is Legacy's first-in-the-industry system for fast grease reloading. The LOCK-N-LOAD thread-less, quick connect barrel lets you reload grease in half the time compared to other grease guns. Just slide the LOCK-N-LOAD switch to disengage or reconnect the barrel.
Never worry about crossing threads on your barrel again, and get fast priming every time.
