    Magpul did a good job creating this lower vise block

    Solid tool if you work on your guns

  3. Anthony Asay (verified owner)

    A very important piece if you work on your AR.

  4. Hector Vargas (verified owner)

    Good price. Good construction. Great for maintenance and muzzle work.

  5. Jack (verified owner)

    Really sturdy tool – you won’t be disappointed. It’s a lot heftier than it looks probably due to the steel core.
