Key Features & Benefits
1. High-Friction “Sticky” Non-Skid Work Surface
The defining feature of the Ransom Master Mat is its extremely high coefficient of friction—it’s designed to feel almost “sticky” so parts don’t slide away or roll off the bench while you’re working. Springs, pins, screws, and tiny detents stay where you put them, giving you more control and fewer lost parts during detailed assemblies and disassemblies. Primary Tactical
2. Smart Molded Trays, Raised Edges & Fluid Containment
The surface is molded with ribbed compartments and raised perimeter rims, creating natural “catch zones” for small components and fluids. Spilled solvents, oils, or cleaning solutions are contained on the mat instead of running across your bench, and small parts can be sorted into the built-in trays away from your main work area.

3. Ideal Size for the Real-World Bench
With an overall footprint of approximately 19.25" x 11.75", the MASTER MAT RS-40-400 gives you plenty of usable space without overwhelming your bench. It’s large enough to comfortably service handguns, bolts, optics, and subassemblies, while still fitting on crowded workbenches, reloading tables, and range stations. Primary Tactical+1
4. Flexible, Rollable & Always Lays Flat
Made from a durable, flexible plastic/rubber compound, this bench mat easily rolls up for storage or transport and springs back to a flat, usable surface without developing creases or “memory.” Toss it in a range bag, toolbox, or truck and it’s ready to go when you are. Primary Tactical+1
5. Light Gray Color for Maximum Visibility
The mat’s light gray color is intentional: contrast makes it easier to see dark or small parts against the surface. No more hunting for a black spring on a dark bench—parts visually “pop” against the lighter background, reducing frustration and speeding up your work. Primary Tactical
6. Exceptional Chemical Resistance
The MASTER MAT RS-40-400 is built to thrive in a cleaning environment. It’s highly resistant to common gun cleaners, lubes, petroleum-based solvents, carburetor cleaners, paints, varnishes, and brake fluids, so you can use your preferred products without worrying about eating your mat. ransomrest.com+1
7. Easy to Clean & Maintain
Keeping the mat fresh is simple. For routine cleanup, soap and water usually do the job. More stubborn grime can be handled with common household cleaners, rubbing alcohol, or even a bit of WD-40 to lift smudges and residues. Just wipe it down and it’s ready for the next project. ransomrest.com+1
8. Built for Firearms – and So Much More
While this is marketed as a gun cleaning mat, its cushioned, non-skid, chemically resistant design makes it an excellent work surface for:
Gunsmithing and routine handgun/rifle/shotgun maintenance
Optics mounting and scope work
Rebuilding carburetors and small engines
RC car & drone repairs
Precision hobby projects and home shop work
Household crafts where you want to protect tables and keep small pieces organized
If you work with precision parts, the Ransom Master Mat becomes a go-to bench accessory far beyond gun care. ransomrest.com+1
Durability, Heat Guidance & Best Practices
The MASTER MAT RS-40-400 is tough and long-lasting, but like any quality tool, it has recommended limits:
The mat material is rated to around 350°F, but direct heat and hot plates above ~200°F can burn, mar, or distort the surface, so heat is not recommended for normal use. ransomrest.com+1
Acetone and MEK-class solvents can soften the material if left sitting on the surface; if you use them, wipe them off promptly. ransomrest.com+1
Some things are permanently… permanent: permanent markers, stickers, and long-standing oils or cleaners can leave stains. These don’t affect functionality, but if you want your mat to stay looking fresh, wipe it down after use. ransomrest.com+1
