- The line
- NO-M.A.R sold since 2012. 4,000+ gunsmithing tools and tool sets sold through our own online stores since January 2023.
The founder designed every tool in the line and the process to make it. In 2026 she chose this shop to carry it forward.
“The ability to clamp the entire upper receiver in the vise instead of just the lower half makes rebarreling a snap.”
“Block is built well and strong. It fits in the lower snug as intended. A must have for assemblies and disassemblies.”
