Negative Airsoft demonstrates how to install the F-Bomb hop rubber into various airsoft barrels and hop-up units. He shows that the process involves lining up the ridge of the rubber with the barrel's groove and carefully sliding it into the hop-up unit. He emphasizes that this component is compatible with a wide range of brands, from standard factory parts to custom setups, and notes that grease should be avoided during installation as it is counterproductive to the rubber's function.

To prove the durability of the product, Negative Airsoft subjects a single hop rubber to a series of rough installations and removals across different, sometimes rusty, hardware. He even draws a small anatomical doodle on the rubber to track its condition throughout the testing. Despite being "less than gentle" and intentionally messy with the parts, the rubber remains intact, showing no signs of tearing or deformation even after being stuffed into several different units.

He shares a maintenance tip and a final stress test. After cleaning the rubber in warm soapy water to remove the grime from the previous tests, he attempts to physically rip the patch to show its strength. He reminds his viewers that while the material is tough, proper alignment is still the key to consistent performance.
