OEM & Contract Firearms Manufacturing
High-volume CNC machining of firearms components for OEMs, defense contractors, and private label manufacturers. Precision mil-spec parts from prototype to millions.
Firearms & Defense Manufacturing Machining
TXSwiss is a contract firearms component manufacturer producing precision-machined parts for firearms OEMs, defense contractors, and private label brands. We specialize in high-volume Swiss CNC production of bolt carrier groups (BCGs), upper and lower receiver components, fire control parts, buffer tubes, and barrel extensions. Our 24/7 production capabilities and ISO 9001:2015 quality systems deliver the consistency, traceability, and volume that firearms manufacturing programs demand.
Firearms manufacturing requires a machine shop that understands mil-spec tolerances, proper material selection, and the critical nature of every component. TXSwiss has deep experience machining Carpenter 158, 9310 steel, 8620 steel, and 7075-T6 aluminum for firearms applications. We produce parts that meet Technical Data Package (TDP) requirements with full material traceability, MPI-ready processes, and the production volume to support programs from prototype runs through millions of units.
Firearms & Defense Manufacturing Components
Materials We Machine for Firearms & Defense Manufacturing
Carpenter 158 Steel
Mil-spec bolt steel — the standard for M16/AR-15 bolts. Heat treated to 26-32 HRC, MPI tested
9310 Steel
Premium bolt and carrier steel with superior toughness and fatigue resistance over Carpenter 158
8620 Steel
Mil-spec bolt carrier steel — case-hardenable for wear resistance with a tough core
7075-T6 Aluminum
Mil-spec receiver aluminum for upper and lower receivers, buffer tubes, and charging handles
4150 CMV (Chrome Moly Vanadium)
Mil-spec barrel steel — chrome-lined or nitrided for extended service life
4140 Chrome Moly Steel
Standard barrel and gas block steel — heat-treatable for high-strength components
4340 & 300M Alloy Steel
Ultra-high-strength steels for critical structural and ordnance components
S7 Tool Steel
Premium trigger, hammer, and enhanced bolt steel — extreme impact resistance
17-4 PH Stainless Steel
Corrosion-resistant, precipitation-hardened steel for adjustable gas blocks and pins
Brass C260/C270
Cartridge brass for ammunition casings — high formability and corrosion resistance
