I had a look through my BBB ( Big Box of Bits

) and had a look at my old hop unit and did a few comparisons, and its not good news

The VSR rubber would fit if you cut the front lip off and sealed it with teflon tape, silicon sealant, or my new fave whipping method but it would require substancial work to the nozzle seal as they are nowhere near the same size, in that the VSR has a bigger hole

If you could glue a piece of rubber tube into the VSR rubbers hole that corresponded with internal and external sizes of the L96 type then you may get lucky, but past that your stuck or like zulu says buy upgrade parts. If it helps I fitted a CA M24 hop unit into mine, non standard of coarse as nothing of mine is stock for long

, it was a bit of a fiddle to get it to fit but transformed the gun. I had an opportunity to do a side to side test against a stock Well 96 of my mates and he went away wanting me to do the same mods to his if he bought a new hop unit....., if you needed any coaxing to upgrade yours
