Gunsmithing and Firearm Machining Service Pricing
Selected Gunsmithing and Machining Work
Every project shown below was completed by Nexus Defense & Machine Co. This gallery includes barrel threading and crowning, SBR conversions, pin-and-weld work, AR and AK platform work, firearm engraving, custom tooling and specialty machining. Because every firearm and project presents different requirements, many services are listed with starting prices or quoted individually after evaluation.
Nexus Defense & Machine Co. provides precision gunsmithing, firearm machining and custom fabrication services from our shop in Holland, Pennsylvania.
The prices listed below are starting prices for standard work on clean, serviceable firearms and components. Final pricing may vary depending on firearm condition, required disassembly, previous modifications, parts compatibility, setup requirements and the overall complexity of the project.
A final estimate will be provided after the firearm or component has been evaluated. We will contact you for approval before performing additional work that would materially increase the original estimate.
