A New Brand – A New Distinction. Customization with the CGJ Signature

For some time now, we’ve been consistently showing you—across our social media channels and on YouTube—the direction in which the Jammas gunsmith workshop is evolving. Today, we’re adding another clear accent. One that says it plainly: this is not mass-produced work—this is craftsmanship with character.

We have expanded our gunsmithing offer to include advanced firearm customization, understood not as simply “adding accessories,” but as a genuine intervention in the form, ergonomics, and overall character of the firearm. In practice, this includes, among others:

  • precise stippling of polymer components,
  • laser engraving of metal surfaces,
  • professional Cerakote finishing of complete builds and individual components.

Importantly, the vast majority of our projects are created based on our own designs as well as individual concepts provided by our customers. Each customization is unique—designed for a specific user, their needs, shooting style, and aesthetic preferences. And that is exactly what true customization is about: minimal repetition, maximum character.

The Craftsman’s Signature Matters

Individual work deserves individual identification. That is why we are introducing the CGJ stamp, which—only with the client’s consent—will be used to mark the customizations we perform.

This is not a marketing gimmick, nor “a logo for the sake of a logo.”
It is a maker’s mark—the craftsman’s signature and a confirmation of origin and quality.

We want our builds to:

  • not get lost among countless off-the-shelf modifications,
  • be unmistakably associated with a high workshop standard,
  • clearly communicate: this was made at the Jammas gunsmith workshop—deliberately, precisely, and without compromise.

Craftsmanship, Not Mass Production

The stamp does not change the function of the firearm.
It adds identity.

For us, this is a natural stage in the development of a gunsmith workshop focused on quality, responsibility, and an authorial approach to every project. For you, it is a clear signal that you are holding something more than a modified firearm—you are holding a piece of workshop craftsmanship, signed.

What’s Next? A One-of-a-Kind Competition

Since we’re talking about customization with character, we’re taking it one step further.

Soon, we will announce a customization competition for the IWI Zion-15 rifle, purchased this year from us or our partners. It will be a space for your ideas, vision, and design courage—from ergonomics and function to form and finish.

We’ll reveal the details, rules, and prizes shortly, but one thing we can already say:
this won’t be a contest for “the most accessories,” but for the best-thought-out customization.

If you have an idea of what your Zion-15 should look like—start shaping the concept.
We’ll take care of the craftsmanship.

Because good craftsmanship doesn’t need to shout.
It’s enough that it leaves its mark.
