De las mejores gomas que e usado

Llevo tiempo usando esta goma en todas mis réplica y le da una muy buena consistencia al tiro.

Great for pistol, terrible in rifle

I tried this hob rubber in my tm vsr-10, (action army hop unit, 303mm 6.02 maple leaf inner barrel, Tridos TDC), at 0.95 Joules it was struggling to hop 0.25g bbs, when with the same exact rifle only using a sniper mechanics flamingo 50* it can easilly hop 0.40g bbs.
I then put the 4uantum into my (stock) AAP-01, and at 0.8 Joules it was able to hop 0.40g bbs easily.
I swapped it back into my VSR incase it had taken some shots to 'break in' and it was the same verdict, amazing in the pistol, apalling in the rifle.
All testing was done within one game day in which the weather and temperature stayed relatively constant.
(Joules so low due to legal restrictions where i live.)

Sorry to hear that it did not perform great in your TM VSR-10. We've seen that certain buckings don't perform well in certain setups therefore we always encourage testing multiple ones to see which one works great in your case. 4UAD buckings were primarily designed for GBB replicas in mind and we've heard overwhelmingly positive feedback in most cases regarding these. Another thing is that <1J sniping generally is more tricky due to the low power and it looks like 4UAD might not be the best case in this situation.

Accuracy

It's +- the same as a Flamingo 60* I can hit a headshot on 60m with every shot on .48 and 3j

Este Bucking es mejor que el que me trae mi SSP18 de serie?

This depends on what weight BB's you are using. If you're using 0.3 or lower you will probaby not notice a difference. But using 0.32g or higher, you will likely notice a better performance out of the 4UAD bucking. But don't expect anything magical on a pistol as there are so many inconsistent variables on gas blowback replicas.
