R-Series Front Cap Compatibility

The following suppressors share interchangeable R-Series front caps. End caps can be swapped to a smaller caliber-specific aperture for added suppression (1–3 dB benefit) or to a flash hider cap for reduced muzzle signature. Do NOT shoot a larger caliber through a smaller-bore front cap.

Sandman S / L / X
Wolverine
Nomad (all versions)
Wolfman
Primal

KeyMo vs. Xeno — Key Differences

KeyMo: older/larger QD interface; ships with a 5/8×24 muzzle brake. Wide device ecosystem. Compatible with Sandman S/L/X, Sierra 5, Nomad, CT5P.
Xeno: newer/smaller QD interface; ships with Xeno Radial Brake. Compatible with Sandman X, Nomad Ti XC, Sierra 5, CT5P. Not cross-compatible with KeyMo muzzle devices.
Sandman X is available in both KeyMo and Xeno configurations — choose based on existing muzzle device investment.
