Really good video! I Just wish that the barrels were cleaned before the first test, that way we can see the actual difference the bucking made on it's own. Pretty obvious that a dirty barrel is going to skew results, no matter what bucking you have installed.
@judeabrigo2784 күн бұрын
exactly my thoughts
@pyroromancer11 ай бұрын
consistency is what seperates a piece of silicon from a proper bucking. One thing TM units have going for them is how most of them are easy to disassemble for maintenance and awapping out parts. I remember when i was 15 y/o i was able to swap out barrel and bucking of my TM G36C easily. 15+ years later uaing mostly GBB, its like each individual rifle has a unique disassembly procedure, depending on who at the factory assembled the unit. VFC and GHK especially suffer from this issue.

Hello guys👋🏻 So i just ordered the bucking and would like to ask both 4uad and the people in the community who have the bucking installed which nozzle works good with the aeg version. I intend to use it with the silent industries aeg hup unit to increase the tension to the feeding lips to replicate the effect of the magnus pro tension sleeve to quote "make it bite into the nozzle better". which leads me to the question which nozzle profile(nozzle tip with rounded edges, flat nozzle tip, or the pointy one that gets very small at the tip) interfaces the best with the friction pro feed lip. Any halp would be appreciated👍🏻.

I dont see any improvement with your new bucking vs other brand buckings. Because you cleaned the guns and replaced worn out and dirty buckings with a new clean buckings. You need to test your bucking against brand new bucking from other brands, in a new gun.
