T-Doll Analysis


Special Equipment
Inherited Weapon Arsenal


M4A1 is given for free through Main Quest after clearing chapter 2-6. She is quite strong even pre-mod and is highly recommended to be used in your first ARSMG.

She both has a good self-buff to Damage as well as very good tiles helping your other two ARs kill things faster.

M4A1's Mod is one of the strongest mods in the game, as it opens up so much potential with the Cannon Mode. Her Skill 2 makes it so that when her Skill 1 is activated while 3 or less Dolls are on the field, she will pull out her Cannon and start blasting, dealing massively increased damage with an AoE at the cost of RoF.

The main thing to note with this is that using M4A1 in an Exodia comp dedicated to her Cannon Mode has much higher skill requirements than most normal echelons. You need to activate HG Skills before retreating them, and only then activating M4's Skill to let her start blasting. As such, using her for this purpose will require some decent kiting knowledge, for which you should see the Kiting Basics page to learn more.

For farming, this obviously requires no more than 3 Dolls in the echelon to be AFKable, but any farming recommendations you see using M4A1 should already have taken this into account.

M4A1 can also obviously still be used in a normal ARSMG, as her tiles and Skill 1 both got some minor buffs from her Mod.

Strong Tiles

M4A1's tiles are very strong, providing 18% Damage and 30% Crit Rate to other ARs.

Strong Skill

Her Skill is also quite strong, having a decent uptime of 10/16, a low ICD of only 4 seconds and 70% increased Damage.


OP Skill 2

With a dedicated team to support her, M4A1's Cannon Mode can obliterate enemy formations in the blink of an eye.

Amazing Mod SPEQ

M4A1's Mod 3 SPEQ grants +15 DMG, 20 RoF and +15 Armor. This is extremely strong, basically a chip with Armor instead of a Crit Damage penalty. The Armor is also nice for reducing any chip damage she might receive, such as in farm comps.


Hard to Use

M4A1 in a full Exodia comp is very hard to use compared to normal echelons.

Full Analysis

M4A1 Mod's Cannon Mode is not a normal Damage buff, but rather a Damage multiplier on her hits. As such attempting to copy stats from her will not work as expected.

Her Cannon Mode works as follows:

  • Main Target hits are Surehit and Cannot Crit.
  • Secondary explosions are affected by Accuracy and Can Crit.
  • None of the hits are linksplash, but depend on M4A1's own links to deal full damage.

If you are using M4A1 in a regular ARSMG, and you are also intending to use SOPMOD Mod with her, be aware that SOPMOD's Skill 2 grenades will target M4's current target. This is an anti-synergy and is negative in almost all situations.

Team Options

Pre-Mod M4A1 should be used in the recommended first ARSMG echelon with UMP45, ST AR-15, Micro Uzi and either 416 or M4 SOPMOD II.

See Teambuilding Basics and the two subsequent pages for more details.

Team Options

A standard M4 Exodia will have Kolibri, Webley, Stechkin as well as one of the following:

  • If you need knockbacks or Armor tanking, LTLX7000.
  • If you need HP Shield and/or Evasion tanking, Suomi Mod.
  • If you need neither of the above, M950A Mod for just more Damage output.

Compared to the M4 carbine, the M4A1 carbine is an alternate fully automatic version that was primarily intended for and used in spec-ops operations. Its design was unveiled in 1991, and it took an additional 3 years for it to finally be put into service.

Contemporarily, the M4A1 carbine has been redesigned to improve heat dissipation and accuracy by thickening the weapon’s profile under its handguard. These redesigns have also included a heavier buffer, the H2. This modified M4A1 is typically differentiated in certain circles with the label of Model 921HB (Heavy Barrel), but more commonly is referred to and designated as the M4A1 along with its unmodified counterpart.
