Gray Zone Warfare: How to Build the M4 CAR-15

Do you remember watching old war films, like Full Metal Jacket and Platoon, and thinking how awe-inspiring their weaponry was at the time? It was a horrible, terrifying period in human history, but we can appreciate the firearms, right? If that’s the case, here’s how to build an M4 in Gray Zone Warfare based on the iconic CAR-15 used by Special Forces in Vietnam.

How to Build the CAR-15 M4 in Gray Zone Warfare

It’s relatively simple to build the CAR-15 M4 in Gray Zone Warfare. Every component you require is available from day one, even at your lowest level, by speaking to Gunny. He’ll sell the whole lot for less than $1.3k, and it’s a fun weapon to use in the game!

To build a classic M4 in Gray Zone Warfare based on the old-school CAR-15, which saw some use by Special Forces in Vietnam, you will need to buy the following parts from Gunny:

  • M4 Upper
  • M4 Lower
  • M4 Buffer Tube
  • M4 Stock
  • M4 Carbine Handguard
  • AR-15 Barrel – 10.5″
  • M4A1 Standard Gas Block
  • M4QD Flash Hider – KAC QD
  • AR-15 Carrying Handle
  • MOE Pistol Grip
  • AR-15 5.56x45mm 20-Round PMAG Magazine

This setup will cost approximately $1.2K from Gunny, around the same price as buying a fully functional M4A1 from his shop. This rifle is much, much cooler, though!

What’s the Appeal of the Vietnam-era CAR-15 in Gray Zone Warfare?

Besides the iconic factor of using this weapon, the recreated CAR-15, built around an M4 in Gray Zone Warfare, proves relatively lightweight, highly maneuverable, and accurate in mid-range combat. It’s a fantastic starting weapon for those new players on a budget who don’t want to run the same old M4A1 mission after mission.

That said, this is not your weapon if you want accuracy at range. It drops off quickly, unfortunately, and the ergonomics could use some improvement. But hey, that’s what you get for using an old-school weapon before ergonomic designs became the norm!
