MadBull Hitman Compensator for M9 Airsoft GBB Pistols

"DO NOT BUY.!!!! I bought for my we samurai edge m9 and 20 seconds after install the spring guide snapped inside the gun. I had to take the entire gun apart. so now i cant use the compensator. Its looks awesome so im really disappointed that it broke right after putting it on. Only cheap thing is the spring guide other than that its awesome.
