Our accessory items are constructed from glass-filled nylon, offering a rugged feel and superior impact resistance. The material is weather-resistant to ensure performance remains consistent in rain or snow conditions.
We utilize steel inserts in high-stress threads to prevent stripping during installation. This makes our mounts and rails durable enough for heavy optics and tactical lights, keeping your setup solid.
The anodized finish we use is formulated to resist scratches and gun cleaning chemicals. This ensures the accessory stays looking professional, maintaining the firearm’s resale value over time.
Our tactical pouches and carrier gear are manufactured with 1000-denier Cordura nylon. We inspect each seam individually for double-stitching and overall finish before packaging, providing excellence for operators.
Our engineering team draws inspiration from modern military requirements and active shooter feedback. This results in accessories that improve weapon handling and target acquisition speed in close quarters combat.
We package our products in secure boxes to reduce shipping damage. Our commitment to quality extends from our raw material selection to our customer service response times, ensuring total satisfaction.
The mounting clamps are designed to fit securely on both MIL-STD 1913 Picatinny and Weaver rails. This dual compatibility ensures you can install the accessory on a wide variety of weapon platforms.
Our holsters are custom-molded to the exact dimensions of the firearm model, providing a secure friction fit and positive retention click when the handgun is fully holstered.
We use heavy-duty steel springs in our magazine extensions to ensure positive feeding up to the last round. This prevents feeding failures during fast tactical reloads.
The weapon lights feature high-output LED emitters that produce a blinding white beam, allowing you to identify targets and search dark areas with complete confidence.
