Viseblox Lock & Hold AR15 / M4

The last Vise Block you will every buy. The Lock & Hold is the strongest, most durable vise block providing you with complete lock up of your firearm when clamped in a vice. Adjustable tension bolts allow you to lock it down to your mag well tight enough where you cannot remove it or just enough for a snug slip fit. This block will not allow your firearm to move while staking and torqueing castle nuts. A must have for when you are cleaning, building and servicing your firearm.

The Lock & Hold will hold all rifles that utilize the AR Pattern magazine. Made by hand from billet aluminum and PVC plastic to give you the durability you need in a vise with clamping power and the non-marring hold in your mag well. All associated hardware is stainless steel. This vise block will last you for decades.
