The sling swivel, a seemingly insignificant component, is nonetheless critical to the carry and use of any rifle intended for hunting or self-defense. And the U.S.-made GroveTec Mil-Force swivel—so-named because it meets or exceeds all U.S. military specifications—is tougher than most. Available for both 1" and 1¼" slings, the swivel has a one-piece body investment cast of 8620 steel and features a knurled steel locking collar. A low-key gray zinc-phosphate finish adds durability. Price: $23 per pair. Contact: GroveTec U.S., Inc., P.O. Box 220060, Milwaukie, OR 97269; (503) 557-4689; grovtec.com.
