The 6.5 Grendel bolt carrier group (BCG) is a critical upgrade for AR-15 builders looking to tap into the long-range potential of the Grendel cartridge. Whether you're optimizing a hunting rifle or building a designated marksman rifle (DMR), the right BCG makes the difference between good and exceptional performance.

At Mounts Plus, we offer drop-in ready, Type II Grendel BCGs built to handle the higher pressure and longer case head of 6.5 Grendel. Choose from Nickel Boron, Black Nitride, and EXO coated options—backed by brands like Faxon Firearms and Fail Zero.

⚙️ Why You Need a Dedicated 6.5 Grendel BCG

The 6.5 Grendel round requires a Type II bolt face, designed specifically to accommodate its unique case dimensions. A standard 5.56 BCG won’t cut it—misfeeds, failures to extract, and inconsistent headspacing are risks you don’t want.

A purpose-built 6.5 Grendel BCG ensures proper fit, safe operation, and reliable performance, especially in high-stress environments like long-range shooting or hunting.
