What is 6.5 grendel?

6.5 Grendel

The 6.5 Grendel is an intermediate rifle cartridge designed by Bill Alexander of Alexander Arms in 2003 as a low-recoil, accurate cartridge specifically for the AR-15 platform. It is intended as a more effective 200- to 800-yard cartridge than the 5.56×45mm NATO.

• Design and Purpose: The 6.5 Grendel was designed to provide superior external ballistics and terminal performance compared to the 5.56 NATO cartridge within the AR-15 platform. Its primary design goals were to offer an effective combat cartridge at extended ranges while still fitting within the dimensional constraints of the AR-15 magazine well.

• Ballistics: It offers a flatter trajectory and retains more energy at longer ranges compared to the 5.56 NATO. The high ballistic coefficient bullets used in the 6.5 Grendel help it resist wind drift and maintain velocity.

• Cartridge Dimensions: The 6.5 Grendel utilizes a 0.264-inch diameter bullet, which is larger than the 5.56's 0.224-inch diameter. It has a case length of 39 mm.

• AR-15 Compatibility: The 6.5 Grendel requires a modified bolt and magazine to function reliably in an AR-15. The standard AR-15 lower receiver can be used, simplifying the conversion process.

• Common Uses: It's commonly used in target%20shooting, hunting (especially for medium-sized game), and some military%20applications. It's also gained popularity in precision%20shooting competitions due to its accuracy and ballistic performance.

• Pros:

  • Excellent ballistics for the AR-15 platform.
  • Effective range beyond that of the 5.56 NATO.
  • Manageable recoil.
  • Good accuracy potential.

• Cons:

  • Requires dedicated bolt and magazines.
  • Ammunition and components can be more expensive than 5.56 NATO.
  • Reduced magazine capacity compared to 5.56 NATO.
