My first PCP was a Benjamin Marauder in .25, which I still have but was years of shooting it before I started changing any of the factory setting or changing any parts. Next up was the Sam Yang Recluse .357/9mm. I sent the Recluse directly to a guy known for tuning them for best efficiency before even shooting it, Been a slew of others between then and now including a couple more Korean guns, an FX Bobcat and I have several from Airforce in .22, custom build .30 and .308, but I am currently steadily involved with my FX Impact, for better or worse. This thing is by far my favorite and most hate
