Best M4A1 loadout in Battlefield 6

may have 45 weapons to unlock, but there's only one you'll ever need: the trusty M4A1 carbine you unlock at Rank 2. Just a few minutes into your first game, and you'll be well on your way to having the best M4A1 loadout, dominating close range and often outmatching even assault rifles at range (provided you're burst firing, of course). It's my most-used weapon so far, and I wouldn't have it any other way.

If you ufa888 played the beta back in August, then this might not come as a surprise to you; the M4A1 was arguably the best gun then, and it still holds strong despite some changes since. So, here's what attachments you need for a solid M4A1 build.

Best M4A1 loadout in Battlefield 6

Here's the build I've been using for the M4A1:

• Muzzle: Convertor Linear Comp (10)
• Barrel: Light 12.5" Fluted (20)
• Underbarrel: 6H64 Vertical (25)
• Magazine: 30RND Fast Magazine (10)
• Ammunition: Standard (5)
• Scope: Mini Flex 1.00x (10) or RO-M 1.75x (10)
• Accessory: 50MW Blue (20)

The M4A1 is an absolute bullet hose with a 900RPM fire rate, so this comes with quite the kick. Thanks to recoil/inaccuracy increases at launch, the Convertor muzzle and 6H64 Vertical grip are now your best options to reduce this recoil to a more than controllable level. The only downside is that this grip hurts your accuracy while moving, though there are ways to fix this. Until you've unlocked this grip, use lower-level alternatives like the Alloy Vertical.

With the recoil under control with just these two attachments, I use the Light 12.5" Fluted barrel, primarily because it improves ADS accuracy while moving, but also speeds up ADS transition. This effectively counteracts the downsides of the 6H64 grip. The Light barrel is unlocked g2g1bet at Mastery 25, so stick to the standard 12.5" Mid barrel and then the 14.5" Carbine barrel until you've unlocked it.

A fast fire rate also means the M4A1 burns through ammo, and unfortunately, larger magazines are extortionate, while also hurting your mobility. Instead, I recommend using the 30RND Fast Magazine, as this gives you the fastest reload possible at just over two seconds. It's better than using the standard 30RND mag with a mag catch for the same total price, though that's what you'll have to use until you've unlocked this upgraded magazine.

Last but by no means least is the 50MW Blue laser accessory. Unlocked at Master 26, this accessory takes a while to unlock, but it's a fantastic attachment on nearly every weapon, especially on close-range weapons. The 50MW Blue handily increases hipfire accuracy, but, more importantly, it also gives a minor boost to aiming accuracy. Like the Light barrel, this is great at countering our choice of grip to ensure your barrage of bullets more consistently go where you aim. Use the 5MW Red until you've unlocked the 50MW Blue.

The last 10 attachment points go to your optic of choice. This is almost entirely down to personal preference, though I'd recommend checking out the Mini Flex 1.00x or RO-M 1.75x, depending on the map. The Mini Flex is the clearest close-range red dot, while the RO-M's enhanced magnification is great for slightly larger maps.

Since the M4A1 is a carbine, none of the classes gain any unique benefits while using it. With that said, its very aggressive nature makes it the perfect fit for an Assault using a shotgun on a sling (for a second primary weapon), or a Support as a combat medic, especially since you can resupply your own ammo.
