TNT Airsoft Hop-up Bucking for Gas Blowback Rifles - Set of 2 (Model: KWA/KSC MP7)

"The bucking works great :) unlike the first review I didn't have any issues because I bought the right hopup. The other person used this bucking with the og hop up and not the TNT hop up, this will not work with og kwa gbb hop ups, YOU NEED THE TNT HOP UP TO USE THIS BUCKING......this is why the 2 star review should be deleted, the reviewer made the mistake and didn't pay attention. Not the products or companies fault it didn't work.

I had no issues with this bucking, I just bought 2 more sets.
Have a good day :)

"I bought the kmp9 bucking for my kmp9. I tried installing and i had no dimple for the bear so we made one for it shot straight but with .25s shot a angle upward. With .4s it was fine. Then i tried the other bucking with no modification and it did not work very well. If a did not level the gun, the bb would roll out the barrel because the seal was not very tight. I do not recommend unless you can some how mod it to work.
