M-LOK Fitment Guide

Moruzzi billet-machined carbon fiber M-LOK components are engineered to fit standard Magpul-spec MLOK slot spacing found on most AR-15 and AR-10 free-float handguards.

What Fits | What Does Not Fit

WHAT OUR M-LOK COMPONENTS FIT

  • AR-15 platforms using standard M-LOK handguards
  • AR-10 / LR-308 platforms with standard M-LOK spacing
  • Free-float aluminum handguards with M-LOK slots
  • Most factory and aftermarket M-LOK rails

If your handguard uses standard Magpul-spec M-LOK slots, Moruzzi components will fit properly.

WHAT OUR M-LOK COMPONENTS DO NOT FIT

  • KeyMod handguards
  • Proprietary slot systems (e.g., some LWRC, HK, or brand-specific patterns)
  • Polymer handguards that deviate from M-LOK spec
  • Airsoft replicas with non-spec slot dimensions

If you are unsure whether your rail meets Magpul M-LOK specification, contact us before purchasing.
