Utilized by at-home, DIY builders and professional armorers alike, the Wheeler® AR Armorer's Vise Block is a must-have bench tool for AR-15 owners. The Armorer’s Vise boasts an adjustable magazine well insert, engineered to lock into place using your lower receiver’s magazine release, securing your rifle in place while tightening, torquing, and adjusting small parts. The innovative front support is angle adjustable to support the upper receiver or forend for improved security and stability. The precision-molded base is constructed of stainless steel with a corrosion-resistant finish for lasting strength and reliability, while the non-slip rubber feet keep the vise securely in place for added stability. Better yet, the built-in mag well insert includes a hammer stop and a bolt service station that safely and reliably secures the bolt face for quick disassembly/assembly. Order yours today!
