Brass case cups and brass projectile cups are necessary components for casing and projectile manufacturing. All of First Breach’s cups are made in-house from new, premium brass strip. First Breach’s raw brass strip undergoes a series of quality assurance steps prior to being ran through our machines. Our cup production includes a series of quality control checkpoints. All of First Breach’s products are qualified through First Breach’s MOCs (Match-grade Ocular Checkpoints) as well as our MLTs (Match-grade Laser Terminals), which utilize more than a dozen lasers and high pixel cameras to measure the specifications and composition of every single unit. In addition to these checkpoints, First Breach pulls units from its lines every 15 minutes to perform further tests in our QA (Quality Assurance) laboratory. First Breach’s process ensures that every finished cup is ready to produce a match-grade product, has consistently tight tolerances and reliability, and mitigates variances.
