Poor quality! - AIM Sports Inc AR Armorers Kit

Vise block loose / Tool broke on first use! You get what you pay for with this - more Chinese junk. I used the tool to install a new bustt-stock on my AR and the tang broke off the tool when attempting to torque the nut to spec with a torque wrench. I never achieved the spec torque. The vise block is loose (poor fit) in the mag well and does not hold the lower securely. I would pass on this and invest a little more to get quality that will last and work well for what it is intended for. Learn from my mistake.
