I spend too much time back at base customizing weapons to suit various playstyles. My most recent obsession in Gray Zone Warfare is this close-quarters SBR M4A1. It’s compact, ideal for close-range gunfights, and packs a punch with M855 ammunition in each magazine. Here’s how to build the SBR M4 in Gray Zone Warfare!

How to Use the SBR M4 Properly in Gray Zone Warfare
As much as I love using this SBR M4A1 for CQB encounters in Gray Zone Warfare, unfortunately, it’s less than ideal in most situations. Ideally, you could hit your target from significant distances, and it’s entirely possible with enough skill, but this rifle excels in short-range encounters.
As such, I recommend bringing the SBR M4 to YBL-1 to clear the tight hallways in The Hole or Tiger Bay. The narrow streets and alleys require quick, tight movements and response times—that’s where this rifle excels!
