Depending on their case material and bullet weight, 6.5mm Grendel cartridges weigh 14.7 to 17.8 grams (227 to 275 gr). The case head diameter of the Grendel is the same as that of the 5.6×39mm (.220 Russian), 7.62×39mm and 6.5mm PPC cases.

[6] [5] Soviet 5.6×39mm cartridges were loaded with smokeless powder VT (винтовочный пироксилиновый порох ВТ), as well as Soviet 7.62×54mmR and 9×53mmR hunting cartridges. [7] It is the parent case for the .22 PPC, 6mm PPC, and the 6.5mm Grendel cartridges. [6]
For an ordinary AR-15 rifle chambered for the .223 Rem/5.56mm NATO, a new barrel, magazine and bolt are required to convert to the 6mm ARC. [7] The 6mm ARC utilizes the same bolt head size as the 6.5mm Grendel , and 6.5mm Grendel-compatible AR-pattern box magazines have also been used successfully with the 6mm ARC. [ 8 ]
Therefore, rifle components such as the bolt and magazine are interchangeable between 5.56×45mm and .277 Wolverine firearms, and standard AR-15 magazines can be used with no loss of capacity. A new barrel is the minimum required component to convert a standard AR-15 to .277 Wolverine.
