This AR-15/M16 lower receiver vise block is designed for immobilizing the lower receiver during maintenance. The lower receiver vise block lets you mount any MIL-Spec AR-15/M4 receiver to the vise block, making it ideal for building and assembling your AR15 rifle or pistol. This Lower Receiver Vise Block includes a removable buffer tube mount ring to aid in installing the carbine buffer tube straight and plumb onto the receiver. This gunsmith lower receiver vise block kit will hold and lock the carbine buffer tube in place, so that the castle nut can be properly tightened without misaligning the buffer tube.
