Hop-up Rubber 60° - Soft 2pcs [AimTop]

I love this rubber. I did not notice the form - it has 2 pertruding spikes in the hop up chamber. Please note that it inserts into the chamber even on 0 hop so I adwise not to use it with very light BB-s. With 0.2 it hops them to oblivion with 0 hop.
However, it works EXTREMELY well with heavy BBs. I tried with 0.28 - just a slight touch on the hop up and it shoots amazingly well.
I use it in a DE Honey Badger - compared to the stock rubber this is miles ahead.
With 0.32 it shoots like a laser - so for the price, go for it.
People complained that the nub is not simmetrical. I noticed this as well - one of the nubs is skewed a bit. But for the price it is an amazing thing to have.

This good hop-up rubber. It's very accurate rubber, but its jump is very high. The nub is really bad and not symmetrical.
Overall, it's very good rubber because you get two for the price of one.
I can only recommend.
