Firearms.

Companies that manufacture firearms play a critical role in our country’s safety and security. And they have an unparalleled need to work with suppliers who thoroughly understand and respect the efforts they’re making to design and manufacture products of exceptional quality. 

For decades, DSP has produced high-quality precision components for a variety of firearm platforms and customers. Here’s what we do:

  • Supply receivers, bolts, sights, firing pins, knobs, buttons, rams, chokes and choke extractors
  • Use the right combination of our CNC multi-axis lathes, machining centers and Swiss-turning machines to manufacture complex and delicate components in a single operation
  • Deliver unparalleled quality and service in support of our partners in the firearms and defense industries

Ask Us A Question



I work with over 50 vendors/suppliers as a buyer for GE.
Dubuque Screw Products is by far the best one to work with.
I never have to worry about quality issues because we never have any with them. Always prompt to get with you when placing order or if you are just asking a question. Always willing to go the extra mile for you. They are a A+ business to work with and you will not be sorry doing business with them.
