Hey ThunderCactus..
Sorry sorry sorry.... i do have a G&G green bucking i took of an G&G MP5 top tech!
Disassembled the hole hopup system, and, as WE scar-l hopup unit is clear plastic, luckly i can see throught it!
I was using a madbull bucking, and made a test:
1. With the barrel, bucking, and hopup unit everything assembled together and out of the gun, i tried to move the whole package towards the gearbox in order to check how the "penetration" of the airnozzle into the lips of the bucking was happening....
For my surprise, if i test it 10 times, 4 or 5 times only the nozzle really fits into the bucking lips... the rest of the times instead penetrating, it bends a small portion of the lips at a random position.
My first thoughts were:
1. It may be the cause of such a big fps deviation (10 fps or more)
2. It may be the cause of horizontal or vertical deviation, because if the lip bends at a given position, the air will not blow perfectly behind the bb, instead, a given portion of the bb may not receive air, and theorically it could cause a random spin or at least a random positioning of the bb inside the barrel!
So, i replaced the madbull bucking by the G&G green one, and remade the fitment test.... 10 times 10 successfully penetration of the nozzle into the bucking lips.
OK... reassembled everything and went to the chrono!
No more than 2, or in the worst case, 3 FPS deviation! It's insanelly CONSISTENT AND STABLE! UHULLLLLLLLLLLLL!
I'll become a huge fan of G&G bucking from now on!
Just waiting for the day light to come in order to test it and see how the bb is flying now!
