Angel Custom "W" Hopup Bucking for WE Airsoft GBB Rifles & Pistols / Marui VSR-10 (Type: Under 370 FPS)

"I bought this to use in a We glock 18c, but it did not put enough back spin on the bb. The nub is not large enough for We-tech handguns, unless you use nice .12 gram bbs.

"Lost 45-50 FPS (chrono verified) going from a worn Nineball bucking to this in a Marui Hicapa 5.1. Everything seems fine otherwise, just an absolutely terrible seal.
