🔧 What Makes a Great 6.5 Grendel BCG?

Unlike standard 5.56 BCGs, 6.5 Grendel requires a specific bolt face — typically Type II — and proper metallurgy to withstand the higher pressures of the round.

A quality Grendel BCG should offer:

• Type II bolt compatibility
• 9310 steel bolt construction
• MPI-tested, shot peened finish
• Proper gas key staking and torque
• Durable surface coating (Nickel Boron or Nitride)

🎯 Why 6.5 Grendel Shooters Need a Specific BCG

The 6.5 Grendel’s larger case head means a standard 5.56 bolt won’t work. A compatible BCG ensures:

• Proper bolt face geometry

• Safe chamber pressure handling

• Reliable extraction and cycling

• Long-term bolt lug durability

A mismatch can lead to dangerous malfunctions — always use a bolt carrier group made for 6.5 Grendel.
