Otis Technology
The Otis Pro Plus GS Brass Punch Set is a compact, purpose-built kit for anyone who maintains their own firearms at home. Whether you're doing routine field stripping, installing or removing trigger pins, aligning receiver components, or managing spring retention during assembly, this five-piece set gives you the right tool for the job without overcomplicating your bench setup. Brass construction means you won't mar or damage the parts you're working on—a critical advantage over steel tools when precision firearm assembly is on the line.
Each punch in this set is 4 inches long, sized to handle common pin diameters: 3/32", 3/16", 5/32", 1/8", and 1/4". The hex-machined bodies give you grip confidence and control, while the chamfered striking surface is engineered to reduce burring and deformation—details that matter when you're working with tight tolerances and finished surfaces. Made in the USA, these tools reflect the kind of attention to detail serious shooters expect from Otis Technology.
For gunsmiths, armorers, and dedicated DIY builders, a quality brass punch set is foundational. It'll see regular use in your cleaning kit or reloading bench, and these are tools that earn their place in your gear over time. Brass won't spark, won't leave steel marks on blued or plated finishes, and won't corrode—making this set equally at home in humid climates or after a season of field use.
| Punch Sizes | 3/32", 3/16", 5/32", 1/8", 1/4" |
| Length | 4 inches |
| Material | Corrosion-resistant brass |
| Construction | Hex-machined with chamfered striking surface |
| Pieces Included | 5 |
| Origin | Made in the USA |
Brass punches are ideal for disassembling and reassembling firearms, driving out and installing pins, aligning receiver parts, and holding springs in place during work. Brass is soft enough that it won't damage finished surfaces, bluing, or plating on your firearm parts—unlike steel punches that can leave marks or cause dings.
Brass won't spark, won't corrode over time, and critically, won't mar the surfaces of the parts you're working with. For precision gunsmithing, where protecting the finish and integrity of components matters, brass is the standard choice.
This set covers five standard sizes: 3/32", 3/16", 5/32", 1/8", and 1/4". These sizes handle many common firearms assembly tasks, though you may want to verify your specific build or firearm's pin sizes before ordering.
The chamfered edge on the striking end reduces the chance of burring or deforming the punch head when struck with a hammer or mallet, extending tool life and ensuring cleaner strikes over repeated use.
