FINISH & ANODIZING DISCLAIMER
Anodizing and surface coating processes can produce natural variation from one production batch to the next. The color, shade, or texture of your firearm may differ slightly from what is depicted in product photography. Factors such as lighting conditions, raw material composition, and batch-to-batch manufacturing tolerances all contribute to these differences. Variation in finish is considered normal and does not constitute a defect.
TEST FIRE DISCLAIMER
Most manufacturers perform a standard test fire as part of their quality control process — this applies to complete firearms as well as individual components like upper receiver groups and bolt carrier groups. As a result, you may notice signs of this process upon receiving your item, including brass or carbon residue on internal components or brass witness marks on the case deflector. This is normal and expected.
