While, like the Mauser, commendable for locking the firing pin instead of just the trigger, its fore and aft movement is both easier to operate and it allows lower mounting of telescopic sights, reducing parallax between the line of sight and the line of the bore and increasing the range of distances for which the scope may be reliably sighted-in. Varmint GunUsually a rifle, but not always. A small-caliber firearm or high-powered air gun primarily used for hunting non-native or non-game animals such as rats, squirrels, gophers, jackrabbits, marmots, groundhogs, porcupine, opossum, coyote, skunks, weasels, and other animals considered to be nuisance vermin destructive to native or domestic plants and animals.
