great quality, works perfectly for upper recwiver work by BattleBuilt, Verified Owner, April 24, 2024
Couldn’t ask for a better rig for the price. This thing is great quality and the hpde material really allows you to torque it into the vice whereas some metal units I’ve used in the past cannot.

Works well by Beepboop, Verified Owner, April 5, 2021
This works very well and is easy to use. Securely holds my AR upper (Aero Precision) in place with my cheap table vice. Arrived quickly with good secure packaging. Pins were a little stiff and took a minute to break in due to tight fit.

A must have!! by Brian Seery, Verified Owner, October 11, 2025
