Getting it done with a Marine M27 IAR, ‘aggressive semi-auto fire’ (VIDEOS)

The 2nd Marine Division’s Gunner addresses the applicability of using automatic vs. semi-automatic fire when it comes to putting rounds on target.

In another installment of “Ask the Gunner,” CW5 Christian P. Wade uses a sometimes-suppressed (squee) M27 Infantry Automatic Rifle in 5.56mm to lay down some hate at varying distances to see what works best: pew, pew or pewpewpewpew.

A select-fire variant of the Heckler & Koch HK416, the IAR has been increasingly fielded since 2010 to replace the M249 Squad Automatic Weapon, a more traditional belt-fed light machine gun, in most roles.

“Testing has also conclusively shown that the M249 is a ~12 MOA weapon; far less reliable, responsive, and has a slower rate of fire than our Automatic Rifle,” says Wade in commentary on the unit’s social media account.
