Luth-AR Barrel Vise Jaws Features The Luth-AR Barrel Vise Jaws are machined with grooves specifically designed to cradle an AR-15 or M16 barrel without marring its finish solving one of the most common frustrations in home gunsmithing. Because the grooves accommodate both standard and heavy barrel contours the same set of jaws works across a range of AR-15 builds rather than requiring different jaws for different barrel profiles. This flexibility makes the jaws a practical one-time purchase for builders who work with multiple barrel weights. Clamping the barrel securely without damage is essential when torquing on a barrel nut or handguard and these jaws are built for exactly that job. Constructed from solid high-strength aluminum the jaws resist deforming under the repeated clamping pressure required for barrel installation and removal. At roughly 4 inches long 3.35 inches wide and 3 inches tall they fit standard bench vises without needing custom hardware or modification. This makes them an easy addition to any home or professional gunsmithing bench already set up for AR-15 work. Builders who value a clean undamaged barrel finish will find these jaws a worthwhile investment for any future work on the platform.
