Although I was told by the ASGI Techs that this would fit in my KWA SR10, I was dissapointed when i got it. It definately did NOT fit correctly in the hop-up unit on the KWA SR10. This bucking is thicker than the KWA bucking and actually is not an upgrade in terms of performance (something else ASGI Techs tried to tell me). I would not have tried this had my stock KWA bucking been ripped by my son in an "attempt" to "help" me install my new custom TBB.
Just so you you are aware, I tried this bucking on both a Classic Army 6.04mm 430mm TBB (recommended by the ASGI techs as a good upgrade for the SR10, something they had right) as well as a custom length JBU 6.03mm 425mm TBB. Both worked fine with the KWA 2g bucking but failed miserably with this one.
I finally got it installed through much grease and pushing, however it compressed the rubber making it "longer" than it should have been and therefore making me shave off a part of the bucking to get the plastic lock clip to install properly. It also put undue strain on the front of the hopup and caused a stress fracture in the plastic part that holds the brass locking ring. I must therefore buy a new hop-up unit and bucking. This time I will go with KWA all the way.
Side Note: This might work in other AEG's just fine, but definately doesn't work in the KWA
-Cheap (2 in 1 package plus 2 nubs)
- Thicker than KWA
- WILL NOT WORK IN KWA SR10 correctly (fair warning)
