Fully automatic weapon with incredible popping power.
~ In-game description

Full Auto Rifle is the fourth upgrade of Path 3 for the Sniper Monkey in Bloons TD 6. It allows the Sniper to shoot 2x as fast as the Semi-Automatic, which is ~12.25x faster than a base Sniper. In addition, bullets deal +1 damage to MOAB-class bloons.

This upgrade costs $3,610 on Easy, $4,250 on Medium, $4,590 on Hard, and $5,100 on Impoppable.



Full Auto Rifle is a monkey bearing the aforementioned automatic rifle, which is a long grey rifle bearing a scope with an orange light, having a black, ridged handgrip just in front of the scope, and an orange stripe just behind a suppressor mounted on the barrel. The rifle also has a grey stock. The monkey itself wears a black vest with a hole for its tail, black gloves, a dark grey camo helmet with a camera attached, and orange goggles over its eyes. These orange goggles have a unique double-peak design that splits above where its mouth would presumably be.

Notably, it does not wear any shoes.


Attacks twice as fast, decreasing attack cooldown from 0.2597s to 0.1299s. In addition, bullets deal +1 damage to MOAB-class.

Targeting Priorities[]

Full Auto Rifle targets bloons using the standard targeting priorities. It shoots a snipe attack.

  • First: Targets the first bloon visible within its range.
  • Last: Targets the last bloon visible within its range.
  • Close: Targets the closest bloon visible within its range.
  • Strong: Targets the strongest bloon visible within its range.

Can receive Camo Prioritization with Night Vision Goggles, allowing it to prioritize Camo Bloons over other types.

The main highlight of the Full Auto Rifle is not so much about being an efficient overall DPS tower, but it is more so that it never misses its target provided that the Sniper has a clear Line of Sight. As such, it is an excellent choice for anti-stalling earlier rounds, particularly with the 0-2-4 upgrade with Berserker Brew or Stronger Stimulant, or the 2-0-4 upgrade paired with a decent camo-detecting tower. For most occasions, setting the Full Auto Rifle on Strong is a good choice, although the First target priority is generally more useful for 0-2-4.

The 2-0-4 Full Auto Rifle is somewhat decent against MOABs in the mid-game, but it tends to struggle against the hyperclumped Yellows that it leaves behind in the absence of MOABs. The presence of hyperclumped Yellows can be rectified by utilizing the 0-2-4 Full Auto Rifle paired with Berserker Brew or Stronger Stimulant, which although allows it to pop grouped bloons better, it will lose good single-target DPS over increased grouped popping power.


  • The 2-0-4 upgrade is usually better than the 0-2-4 upgrade in terms of overall single-target damage.
  • Similar to Semi-Automatic, set a 2-0-4 Full Auto Rifle on Strong to combat mid-game MOABs, and set a 0-2-4 Full Auto Rifle on First to optimize its shrapnel shot attacks.
  • Compared to Supply Drop, which costs around $3,000 more expensive than Full Auto Rifle, Full Auto Rifle tends to struggle versus grouped targets. However, Full Auto Rifle has the edge at single-target damage.
  • As of Version 28.0, which nerfed Elite Defender's damage type, a 0-2-4 Full Auto plus a 4-2-0 Stronger Stimulant and a 2-0-0 Village can solo Deflation on Infernal, which can quickly farm XP and Monkey Money.

Version History[]

Very slightly affected by the Version 20.0 Path 3 crosspathing rework, but later buffed in MOAB-class damage to add late-game relevance and enforce Full Auto Rifle as a DPS Sniper. Also a reduced cost in compensation for a damage type rework for purposes of nerfing 0-2-5 Elite Defender.

  • Buff Full Auto Rifle attack speed very slightly increased (0.13s → 0.12985s)
  • Change Description changed from "Fully automatic weapon with incredible popping power." to "Fully automatic weapon with incredible popping power, including damage to Lead Bloons."
[...] As middle path sniper has been feeling to be in a good spot with alchemist buffs, but other uses of sniper shrapnel weak due to lack of alchemist buff, we have decided to swap alchemist buffability over from the number of bounces to the power of the shrapnel itself.
~ Ninja Kiwi, referring to Bouncing Bullets shrapnel rework, also implying all Shrapnel upgrades in general including 0-2-4
  • Buff Full Auto Rifle price reduced from $4,750 → $4,250
  • Nerf Full Auto Rifle base damage type changed from Normal → Sharp
  • Change Description changed from "Fully automatic weapon with incredible popping power, including damage to Lead Bloons." to "Fully automatic weapon with incredible popping power."
[...] Elite Defender falls off a lot after midgame & really lacks any true cross pathing choice, so it has had some MOAB damage added to the base attack with the amount improved from crosspathing.
~ Ninja Kiwi, referring to Elite Defender
  • Buff Full Auto Rifle gains +1 MOAB-class bonus to initial bullet hit
    • Despite the new MOAB-class damage buffs, description has remained unchanged.


Official artwork[]


  • In BTD5 Flash, purchasing Semi-Automatic Rifle allows the Sniper Monkey to pop Lead Bloons even without Full Metal Jacket. This is not the case in the mobile versions of the BTD5 generation or BTD6 for the Semi-Automatic upgrade. However, in BTD6, the Full Auto Rifle initially added automatic lead-popping power as Semi-Automatic Rifle did in BTD5.
    • Automatic lead-popping power for Full Auto Rifle was removed in Version 28.0, while Supply Drop still retains automatic lead-popping.
  • This upgrade decreases the Sniper's height. This can be shown by placing the sniper on the Carrier Flagship's first platform on Encrypted.
  • This upgrade could be abbreviated to FAR, which would be a good pun on its infinite range when there are not Line of Sight obstacles.
  • Full Auto Rifle is the only Tier 4 Sniper Monkey in BTD6 to wear no footwear of any kind.
