Plenty Of Strength To Get Even The Tightest Barrel Loose
One model installs or removes AR-15 barrel extensions safely and easily without making a “wrench” from an old bolt head. Machined, hardened, steel engagement teeth fully engage locking lugs for precise fit; alignment sleeve holds wrench square with barrel, prevents slipping or damage. ¾" hex drive gives plenty of leverage to get really tight extensions loose.
