redfeild accutrac problem

[kingslamon22]

anybody ever have any problems with redfeild accutrac 6-18 loosing its gas?? i heard of this happening before and i purchased one before i heard this. i personally thought it would make a great piece atop my new 111f 300 winmag. i love it already but heard i should watch out for gas escaping causing fogging inside the scope in cold weather. anyone got experience with this model? one person i know bought one brand new way back whene and said its flawless and mine will be as well indefinatly.
