What is a good torque wrench in the $80-$120 range that I can use on my guns and my car?  I guess the range would be 5 foot pounds to 80 foot pounds.  Is that capable with one single wrench or will i need 2 for that range?  IF i need two which one can cover 30+ foot pounds of torque

Sorry,
when i mentioned gunsmithing i should have said attaching barrels, muzzle brakes and other stuff.  One of the guys i shoot with has all the tools for mounting scopes so i can borrow from him for the light stuff

Keep in mind that the vernier-type (click-type) must be calibrated every so often, while the old, beam-style, barring damage, does not.
Calibration costs money, and may involve sending the wrench off to be serviced.
While it would make sense for a mechanic who's torquing 16 head bolts to use a vernier-type, I question if a gunsmith has that type of need for same.
Get a good beam-style wrench, and try to get one(s) where the torque figures you are going to be using are about in the middle of their scale.
