Great vise block! - Real Avid Smart-Fit AR15 Vise Block

I used the Real Avid Smart-Fit AR15 vise block on my second build of an Anderson Manufacturing build kit. On my first build, I only used my vice. With the second build, I used the Real Avid Smart-Fit AR15 vise block. It was very sturdy and the AR-15 was held in position. The build was much easier with it than without it. It definitely locked my gun in place. A great tool at a great price!
