I have the chance to buy a used Thompson Center Silver Lynx .22LR S/N S2040 in excellent shape for $250.00. Or should I just go get a new Ruger 10/22 synthetic stock gun for $200.00? Myself and almost 13 year old son have been getting into shooting .22LR lately and don't want to use my 50+ year old Marlin 81DL for the amount of shooting we will be doing. I have seen the posts with chipping of the chamber and will need to check the T/C Silver Lynx over again. I have it on hold right now at local Gun shop.
