Free Fire MP40 OB55: Range & Movement Speed Changes
The MP40 has long been one of Free Fire’s most popular and reliable SMGs. In OB55 it received a clear directional adjustment that fits the wider weapon-class philosophy of the update: SMGs are being pushed harder into pure close-range work. The official patch notes list specific changes to the MP40’s range and movement values that every player who still relies on the gun needs to understand.
This guide explains exactly what changed, why it changed, how the gun feels after the adjustment, and how you should adapt your playstyle and loadouts to keep the MP40 effective in the current environment.
Official MP40 Changes in OB55
According to the OB55 weapon balance notes (timed with the broader SMG adjustments that fully land around the early October CS season transition), the MP40 received the following modifications:
- Range: –15%
- Movement Speed: +5%
- Movement Speed while Firing: +15%
These numbers sit inside the larger SMG category direction. Across the class, Garena increased mobility (especially while shooting) while reducing effective range so that SMGs would stop competing as heavily with assault rifles at medium distances.
The MP40 was not the most extreme example — some other SMGs lost more range or gained even higher shooting-movement bonuses — but the changes are still large enough to alter how the gun performs in real matches.
What the Range Reduction Actually Means
A 15% reduction in range shortens the distance at which the MP40 deals its full damage and maintains its previous accuracy and fall-off profile. In practical terms, the gun becomes noticeably weaker once fights stretch beyond true close range.
Situations that used to feel comfortable — holding a medium hallway, spraying across a small open gap between buildings, or challenging an opponent at the edge of SMG distance — now favor the enemy if they are holding an assault rifle or a buffed LMG. The MP40 still kills very quickly when you are inside its ideal window, but that window is smaller than before.
This is intentional. The balance goal is to make SMGs dominate indoors, in tight compounds, and during aggressive close pushes, while making them less attractive as all-purpose weapons that can also hold medium range.
What the Movement Speed Buffs Deliver
The mobility side of the changes is where the MP40 gains new strength.
A flat +5% movement speed makes simply running with the gun equipped feel snappier. More importantly, the +15% movement speed while firing significantly improves the ability to strafe, jiggle, and push while spraying. In close-range gunfights this extra mobility while shooting makes the MP40 harder to track and lets skilled players close distance or dodge more effectively during the magazine.
When the two movement bonuses are combined with the gun’s already high rate of fire, the MP40 becomes a stronger pure entry and close-range dueling tool than it was before the patch. The trade-off is that you must now win the fight inside the shorter effective range or risk losing to weapons that out-range you.
How the Gun Feels After the Changes
Players who pick up the MP40 after the adjustment usually notice two things quickly:
- The gun feels faster and more fluid when moving and shooting at the same time.
- Damage and consistency drop off earlier than muscle memory expects when the target is not truly close.
The first sensation makes the weapon more fun and more lethal in the right situations. The second sensation punishes old habits of taking MP40 fights at distances that used to be acceptable.
Practical Playstyle Adjustments
Play tighter angles
Hold closer corners, swing from nearer cover, and avoid long sightlines. The MP40 now wants you inside the building or right at the doorway rather than challenging from across a street.
Use the new mobility aggressively
The increased movement speed while firing is a real advantage. Strafe more, jiggle peak more, and use the extra speed to close the final meters when you decide to push. Passive MP40 play wastes the buffs.
Pair it correctly
Because the range is shorter, the MP40 works best as a dedicated close-range primary paired with a mid-range secondary (a buffed AR or LMG). Carrying only the MP40 and expecting it to cover every distance is now a liability.
Re-learn the drop-off
Spend time in the training ground or in casual matches simply feeling where the damage starts to fall. The 15% range reduction is large enough that old instincts will get you killed until the new distance becomes automatic.
Entry role
In squad play the MP40 remains an excellent entry weapon. The combination of high fire rate and improved shooting mobility lets the entry fragger create space quickly, provided the fight stays close.
Comparison with Other SMGs in the Same Patch
Several other SMGs received similar or more extreme versions of the same treatment (range down, movement while firing up). The MP40 sits in a balanced spot within that group: meaningful range loss, solid movement gains, and the same familiar handling that many players already trust. It did not become the single strongest SMG, nor did it fall out of viability. It simply became a more specialized close-range tool.
Loadout Advice for the Current Meta
A strong post-OB55 approach is:
- Primary close-range: MP40 (or another mobility-buffed SMG)
- Secondary mid-range: one of the firepower-buffed assault rifles or light machine guns
- Play for the range that matches the gun in your hands at any given moment
When you are holding the MP40, force close distance. When you switch to the AR or LMG, take the longer fight. The clearer weapon-class identities in OB55 reward exactly this kind of disciplined range management.
Common Mistakes to Avoid
- Taking the same medium-range MP40 fights you won before the patch
- Ignoring the movement-while-firing bonus and playing the gun too statically
- Carrying the MP40 as your only weapon into open mid-game rotations
- Assuming the gun is “nerfed into the ground” — it is not; it is re-roled
Final Thoughts
The OB55 changes to the MP40 are straightforward and consistent with the wider SMG direction: less range, more mobility, especially while shooting. The gun loses some of its previous flexibility at medium distance but gains a sharper identity as a fast, aggressive close-range weapon.
Players who adapt by fighting tighter, using the new strafing power, and pairing the MP40 with a proper mid-range secondary will still find it highly effective. Players who continue to treat it as a do-everything SMG will feel the 15% range reduction every time a fight stretches beyond its new comfort zone.
Master the shorter effective range, lean into the improved movement while firing, and the MP40 remains one of the strongest pure close-range options in the current Free Fire environment. The gun did not disappear from the meta — it just demands that you play the range it now owns.
