Devcon Express Epoxy Steel Putty

Devcon Express Epoxy Steel Putty is a two-part epoxy compound designed for gunsmiths, armorers, and serious shooters who need a reliable way to bed rifles, repair metal components, and fill gaps that affect accuracy or function. Unlike temporary fixes, this steel putty creates a permanent, high-strength bond suitable for critical gunsmithing work—from bedding a barreled action to patching non-critical metal surfaces. It's the go-to choice for anyone building or restoring a rifle who demands precision and durability.

The real advantage here is speed and machinability. You can machine or shape Devcon Express Steel Putty just four hours after application, and it reaches full cure in 16 hours. That means you're not waiting days to move to the next step in your build. For those in a hurry, you can accelerate the cure time by applying heat according to the manufacturer's guidance. The putty also resists chemicals and acids, so it won't degrade in harsh conditions or when exposed to solvents and cleaners commonly used in gunsmithing.

Devcon Express Steel Putty meets military specification DOD-C-24176B(SH), which tells you this isn't a consumer-grade filler—it's engineered to perform in demanding applications. The putty form makes it easy to knead, shape, and apply to the exact area you need, and it bonds wood-to-metal and metal-to-metal surfaces alike. If you're faced with voids, cracks, or machine marks that need filling, or you're bedding a rifle action, this putty delivers the strength and workability serious gunsmiths expect.
