  • KeySlot accessory mounting system adds attachment flexibility.

Considerations & Trade-offs

  • Magazine not included, so a compatible magazine must be sourced separately before the chassis is ready to use.
  • The fixed stock design offers a stable setup, but it does not provide the same folding or compact-carry convenience unless an optional folding hinge assembly is added.
  • Optional short/long bridges and weights are available, but they are not included and may be needed to tailor the chassis to a specific setup.
  • Due to the anodizing process, the finish color may vary from the displayed images, so exact appearance should be expected to differ slightly.
