Lyman 7031277 Multi-Caliber Punch Set Roll Pin (1/16, 3/32, 1/8, 5/32) - 4 Pack

Working on firearms means respecting the small details that hold them together. The Lyman multi-caliber punch set roll pin kit gives you four precision punches designed specifically for removing and replacing hollow split roll pins without marring your receiver, trigger assembly, or other critical parts. Whether you're a gunsmith, an armorer, or a shooter who maintains your own rifles and pistols, these punches handle the job that generic drift pins simply can't—the rounded tip seats itself into the pin rather than skating across it, keeping your tool steady and your gun safe.

Each punch in this four-piece set is machined from through-hardened 4140 steel, a material chosen for strength and durability under the kind of repeated use a real gunsmith expects. The knurled grip means you won't lose control mid-stroke, even when you're working in less-than-ideal light or under tension. Roll pin removal is a task where slips cost money and damage—these punches are built to prevent that.

If you reload, work on AR platforms, tune trigger groups, or perform any gunsmithing that involves roll pins, this set covers the most common sizes you'll encounter. It's the kind of tool that justifies itself on the first build.

Frequently Asked Questions

What roll pin sizes does this punch set fit?

The set includes four punches in 1/16, 3/32, 1/8, and 5/32 inch diameters, covering the most common roll pin sizes used in rifle and pistol assembly and repair.

Why is a round-nose punch different from a regular drift pin?

The rounded tip on these punches seats itself into the hollow center of a split roll pin, gripping it firmly and preventing the punch from sliding off and damaging your receiver, trigger assembly, or other precision components. Standard flat or beveled tips can slip and cause costly marks.

What are these punches made of?

They're machined from through-hardened 4140 steel, a material that resists wear and deformation even with repeated use in professional gunsmithing work.

Who should use this tool?

Anyone who builds or maintains firearms—whether you're assembling ARs, working on trigger groups, or performing detailed gunsmithing—will benefit from having the right punch for the job. These are standard equipment for armorers and competitive shooters who tune their own guns.
