Right,some good comments as usual from the lads, now, I have a .177 lgv it is incredible,all I did when I got it was strip it, give it a de-grease,and re lube it with some dr-slide on the piston and bearings, a dab of silicon oil on the piston seal, and some grease sparingly on the spring after polishing the spring ends,it is quite simply,the most accurate,smooth and quiet(yes quiet) springer I have ever owned, and I have had some belters,once you add a silencer,it really does make a dull thuck as it goes off,unbelievable for a spring gun.
They are heavy so if weight is an issue I would avoid
