Questions & Answers
The description says MK3 upper receiver assembly. So does this come with a bolt carrier group or are they adding a dust cover to call it an assembly Expert Answer

The CMMG Mk3 Upper Receiver Assembly 38BA22E-AB does not come with a BCG or Charging Handle. The only part that comes with the CMMG Mk3 Upper Receiver Assembly 38BA22E-AB is the dust cover.

Is this a DPMS HIGH or LOW rail height? Expert Answer

The CMMG Mk3 Upper Receiver Assembly is based on the DPMS LR308 gen1 high-pattern design. So any Gen 1 DPMS high profile handguards will fit this upper.
