+1 RE: CACTUS' comments on HF
If you are after a torque wrench or any other precision tool, forget HF. Besides that, the torque wrench you mention is not "calibrated" (haha) below 20 LB/". Most scope ring cap fasteners require ~15 LB/".
For a gunsmithing torque wrench, get a Borka, which is available here on the Hide. Do a search for the "rave reviews". If I didn't already have a dial Snap-On, Borka would be the one - will probably get one anyway.
