Hey,

I got a firefly hop up soft for my TM 5.1 and when I look into the hop up rubber, it has 2 square notches with a ditch in between (pic below). The stock hop up rubber that came with my 5.1 does not have these notches and has a smooth interior instead. Did I get the right hop up rubber? If so, how do the 2 notches spin the bb? It looks like it would obstuct more than spin the bb.
