Matrix Advanced - Silica Airsoft AEG Hopup Buckings (Set of 2) - 50 Degree / 250~350 FPS

"I purchased these for use in my Army L85 about six months ago. The bucking wraps around a Lonex 509mm x 6.03 barrel, and it sits in a ProWin CNC Hopup chamber. Having an extended cylinder, my RPS is 15, while my FPS is about 340. The accuracy is really nice with tight groupings. Adjustment with the ProWIn keeps the hop rock solid. I am really happy with the performance of the bucking. I have always kept my buckings well lubricated during install, and I am really careful during removal. That way, I assure myself not to tear the bucking. I haven't had any issues since my purchase.
