Description
Working on a suppressor without the right vise block is a good way to gouge a finish you paid good money for. That's exactly what the Energetic Armament Vox Blox 1.38" solves. It's a soft-jaw tool made from high density polyethylene that cradles your can in a standard bench vise, giving you a firm hold without metal-on-metal contact that leads to marring or scratches.
This particular size is cut for 1.38" outer diameter suppressors, and it covers a lot of popular cans. If you own a SilencerCo Octane, a Rugged Obsidian, a YHM Ghost, an AAC TiRant, a Kraken, or a Harvester 300, this is the block you want on the bench. The HDPE material has just enough give to grab the tube securely while still keeping your host safe from the jaws of the vise.
Where the Vox Blox 1.38" Earns Its Keep
Think of it as insurance for any job that needs two hands and a stable can. Changing out mounts, torquing a direct thread adapter, breaking loose a stuck front cap, running maintenance on the baffle stack, or just deep cleaning after a range trip all go smoother when the suppressor isn't rolling around or getting clamped bare. The block does the holding so you can focus on the wrench.
Picking the Right Vox Blox Size
Energetic Armament makes the Vox Blox in a full range of diameters from 1.00" up to 2.00", so matching the block to your suppressor's tube is the whole game. The 1.38" version is one of the more versatile ones in the lineup since so many .30 cal and multi-cal cans land right in that diameter. Measure your suppressor's outer diameter before ordering and you'll be set. It's a simple tool, but once it lives on your bench you'll wonder how you got by without it.

Frequently Asked Questions
What suppressors does the Vox Blox 1.38" fit?
This size is built for suppressors with a 1.38" outer diameter. That includes popular cans like the SilencerCo Octane, AAC TiRant, Kraken, Rugged Obsidian, YHM Ghost, and Harvester 300. If you're unsure, measure the outer diameter of your suppressor tube before ordering to confirm the match.
Will the Vox Blox scratch or mar my suppressor finish?
No, that's the whole point of it. The block is molded from high density polyethylene, a soft material that grips the tube firmly while keeping the hard steel jaws of your vise from ever touching the can. It's a smart way to protect Cerakote and other finishes during maintenance.
What kind of vise do I need to use the Vox Blox?
Any standard bench vise will work. You simply place the two halves of the block around your suppressor, set the assembly in the vise, and tighten down. The block does the gripping so the suppressor stays put while you work.
What jobs is the Vox Blox 1.38" good for?
It's handy for just about any hands-on suppressor task. Swapping mounts and adapters, torquing a direct thread mount, removing a stubborn front cap, servicing the baffle stack, and general cleaning all get easier with the can held steady. It keeps everything stable so you can put both hands on your tools.
