6.5 Grendel

Overview


The 6.5mm Grendel (6.5×39mm) is an intermediate cartridge designed by Arne Brennan, Bill Alexander and Janne Pohjoispää as a low-recoil, high-accuracy cartridge specifically for the AR-15 platform at medium/long range (200–800 yard). The 6.5mm Grendel design goal was to create an effective 200–800 yard STANAG magazine-length cartridge for the AR-15 that surpassed the performance of the native 5.56mm NATO/.223 Remington cartridge. Constrained by the dimension of the magazines, the Grendel designers decided to use a shorter, larger diameter case for higher powder volume while allowing space for long, streamlined, high-ballistic coefficient (BC) bullets.
