There is a particular kind of frustration with this gun. You rush a house, you are a metre from the enemy, you pull the trigger โ and they walk away on 40 HP while you reload. Two seconds later you are on the floor.
The M1887 is the most punishing weapon in Free Fire to get slightly wrong, because it only gives you two shells and it only works inside a very small bubble. But the sensitivity most players carry into that fight was built for sprays, not for a single flick. This page covers what the gun actually does, why one-tap settings are different, and the values to start from.
Numbers first, because almost every claim about this weapon online is a guess:
| Stat | Value | What it means in a fight |
|---|---|---|
| Base damage | 100 | Highest single-shot burst in the game |
| Headshot multiplier | 2.0x | 200 damage โ a full-HP unarmored player dies instantly |
| Pellets per shot | 8 | Spread widens fast; close range is doing the work, not aim |
| Magazine | 2 shells | Two chances, then you are reloading in the open |
| Range stat | 21 | Useful to roughly 10โ12 metres |
| Accuracy stat | 10 | Low by design โ this is not a precision weapon |
That 2.0x multiplier is the whole appeal. One clean headshot is 200 damage, which removes a full-health player with no armour before they can react. Against someone wearing a helmet and vest it will usually not finish in a single pull, which is exactly why the second shell matters and why reload speed is part of the gun's identity.
Think about what your thumb is actually doing in each case.
A spray is a tracking job. The gun climbs, you pull down, you follow a moving target across the screen. You want sliders low enough that small corrections stay small.
A one-tap is one movement. The enemy appears at chest height, you need the crosshair on their head, and you need it there inside about a quarter of a second. There is no correction phase. Either the flick lands or you have burned a shell.
That is why the two setups pull in opposite directions. Our calculator's one-tap profile raises General by 8 and Red Dot by 10 over the base values, and pulls Sniper down by 6 and the fire button down by 2. Close-range sliders go up because the flick needs to arrive; scope sliders go down because you are not using them in this fight and a twitchy 4X slider only makes the gun feel unstable when you do pick one up.
These come straight out of the one-tap profile in our calculator, so the page and the tool agree. Find your RAM tier, then your screen's refresh rate.
| RAM | Refresh | General | Red Dot | 2X | 4X | Sniper | Free Look | Fire Button |
|---|---|---|---|---|---|---|---|---|
| 2 GB | 60 Hz | 200 | 200 | 192 | 178 | 109 | 90 | 50 |
| 2 GB | 90 Hz | 200 | 200 | 194 | 180 | 109 | 90 | 50 |
| 3 GB | 60 Hz | 198 | 196 | 186 | 173 | 104 | 86 | 48 |
| 3 GB | 90 Hz | 200 | 198 | 188 | 175 | 104 | 86 | 48 |
| 4 GB | 60 Hz | 190 | 188 | 178 | 166 | 98 | 82 | 46 |
| 4 GB | 90 Hz | 193 | 190 | 180 | 168 | 98 | 82 | 46 |
| 4 GB | 120 Hz | 196 | 192 | 182 | 170 | 98 | 82 | 46 |
| 6 GB | 60 Hz | 182 | 182 | 172 | 158 | 92 | 78 | 44 |
| 6 GB | 90 Hz | 185 | 184 | 174 | 160 | 92 | 78 | 44 |
| 6 GB | 120 Hz | 188 | 186 | 176 | 162 | 92 | 78 | 44 |
| 8 GB | 90 Hz | 177 | 176 | 166 | 154 | 86 | 74 | 42 |
| 8 GB | 120 Hz | 180 | 178 | 168 | 156 | 86 | 74 | 42 |
| 12 GB | 90 Hz | 169 | 168 | 158 | 146 | 82 | 70 | 40 |
| 12 GB | 120 Hz | 172 | 170 | 160 | 148 | 82 | 70 | 40 |
A pattern worth noticing: the lower your RAM, the higher the numbers go. On a 2GB phone the one-tap profile pins General and Red Dot at the maximum of 200. That is not a mistake โ a budget phone draws fewer frames and registers touch slightly later, so the slider has to do more work to cover the same screen distance in the same moment. A 12GB flagship gets there with 172.
DPI โ the Smallest Width value in Android developer options โ does not change with playstyle. One-tap and spray use the same figure, because it is a property of your display rather than your aim:
| RAM | 2 GB | 3 GB | 4 GB | 6 GB | 8 GB | 12 GB |
|---|---|---|---|---|---|---|
| DPI | 390 | 420 | 460 | 520 | 580 | 640 |
Higher DPI shrinks the interface, which gives your thumb more clear screen to travel across and makes small adjustments finer. Lower DPI makes buttons bigger and easier to hit, which matters more on a cramped budget phone. If you have never touched this setting, change it once and leave it alone for a week โ it changes the feel of everything, not just one gun.
Notice the one-tap profile pulls the fire button down by 2 compared to the base value. That is deliberate, and it is the opposite of what most players assume.
A large fire button is comfortable. It is also a large dead zone sitting on the part of the screen your aiming thumb wants to travel through. With a two-shell gun that needs one fast flick, having your thumb snag on the edge of an oversized button costs you the fight.
The values above land between 40 and 50 depending on your device. Keep it bottom-right and low, so the button sits under your thumb's resting position rather than in the middle of its path. We go deeper on placement in the fire button size and position guide.
The SensiAI Pro Android app reads your device's RAM and refresh rate on its own and builds a one-tap profile for that specific handset โ no working out which row of a table applies to you. It also covers gun-by-gun sensitivity for the rest of your loadout and answers aim questions in English, Hindi and Hinglish.
On an unarmored enemy at close range with a clean headshot, yes โ 100 base damage times the 2.0x head multiplier is 200. Against a player in a helmet and vest it usually will not finish in one pull. That is normal and it is why the gun carries a second shell.
Different RAM tier and often a different refresh rate, so the numbers that suited the old phone are wrong on the new one. Look up your new tier in the table above rather than copying your old settings across.
You can, but you are compromising. One-tap settings sit higher on General and Red Dot than spray settings do. If you mostly rush, build around the one-tap numbers and accept that your long sprays will feel slightly loose.
A little. More frames means the moment you flick is drawn sooner, so the same thumb movement lands marginally earlier. In our numbers the difference between 60Hz and 120Hz on the same phone is about 6 points of General โ real, but much smaller than the difference between RAM tiers.
In close quarters it is still the fastest kill available, and recent updates gave both the standard M1887 and the M1887-X about 10% more range and 10% faster reload. The limitation was never the damage, it was the distance โ and that has not changed much.
