The Delta Series Armorer's Vise provides users an ideal foundation for all AR tasks. Its integrated mag well insert securely engages the lower receiver and adjusts in angle accommodate any task. The innovative front support is angle adjustable, allowing the barrel portion of the upper or a fore end portion to be secured in its tapered profile. Both front and rear supports have multiple positions in the base and are reversible for maximum customization. The base is constructed of rigid steel with non-slip rubber feet that can be removed for permanent bench-top mounting as well. Depressions formed into the base keep spare parts or tools contained. Additional features in the mag well insert include a hammer stop and a bolt service station that secures the bolt face for disassembly/assembly. The vice works great for assembled guns in closed of break open state but also is ideal for holding a lower receiver only, for assemble and maintenance.
