The LA New Product Development Team in Ruston, Louisiana, designs, engineers and prototypes firearm accessories in house while testing materials and handling. Dealers are told lasting products rest on engineering, so they should ask what an item is made from, how it was finished and tested, whether checks used production parts, and which firearm models received actual fit verification. Glass filled nylon is common for polymer frames, magazines and mounts yet absorbs moisture; holsters typically use thermoformed Kydex or Boltaron; 4140 and 4150 steels need protective finishes, 17-4 stainless resists corrosion, and 7075-T6 aluminum is stronger than 6061-T6. Printed nylon suits rapid fit checks across several guns while CNC machined aluminum better supports function testing under recoil, with final checks belonging on production intent parts that carry the real coating. The firm also built online configurators for Big Sight Systems oversized Glock 17 and 22 sights for shooters with declining near vision, a need many later addressed with pistol red dots.
