NcSTAR AR-15 Lower Receiver Vise Block

The NcSTAR AR-15 Lower Receiver Vise Block is designed to secure most AR-15 lowers in place for routine maintenance and in-depth builds. Features lightweight aluminum construction with a scratch- and corrosion-resistant anodized finish. A removable buffer tube mount ring eliminates frustration when installing your buffer tube, ensuring the tube is straight and plumb with the receiver and allowing the castle nut to be properly tightened without misalignment. Includes a pistol grip bolt for additional security and stability.
