The Energetic Armament VOX Blox 1.38-inch (brand part no. EA45) is a purpose-built soft jaw vise block for silencer work. It is machined from high-density polyethylene, so it clamps a suppressor in a bench vise without touching the finish, with no marring and no damage to Cerakote. Use it when you are swapping mounts, servicing baffles or torquing a direct thread adapter. This 1.38-inch size is the match for silencers with a 1.38-inch outer diameter, and the line runs through twelve sizes so you can pick the right one.

Key Specifications

• The jaws are sized for a 1.38-inch outer diameter, so the block supports the silencer body without metal-on-metal contact.
• Energetic Armament lists this size for the Octane, TiRant, Kraken, Obsidian, Ghost and Harvester 300.
• The block is machined from high-density polyethylene, a soft material that does not mar or scratch Cerakote or other finishes.
• It gives a secure vise grip for installing or removing mounts, servicing baffles and torquing a direct thread adapter.
• The VOX Blox line covers 12 sizes from 1.00 to 2.00 inches, so you can match the block to the silencer.
• Energetic Armament makes it in the USA.
• If a silencer runs up to about 0.010 inch larger than the block, the clamp ears can be pried open slightly to fit it.
