I've been using Crosman pellgun oil on the co2 cylinders and the working parts. My gun, a Beretta Storm PX4 uses 16 round dual wheel magazine for pellets or bb's. I was wonder to if I can lube them with pellgun oil or a silicone based, non distillate. They're about a year old and I sprayed them with CRC Spray silicone and it totally froze them up. I didnt read the label where it says DO NOT USE ON PLASTIC. My laziness,, the eyes are getting old and that really small print gets missed. I soaked them in 91% Isopropyl alcohol and that loosed them up but they re still miss firing but getting better. Umarex said to use silicone on them, safe for plastic. I appreciate your replies they really helped.
