Shatter your targets with explosive shells from this devastating Archwing cannon.
The Grattler is a quad-barrel GrineerArch-gun autocannon. Its explosive projectiles make it ideal for clearing out groups of enemies, which is counterbalanced by its limited range and projectile travel time.
As of Update 17.1, the Grattler has a short spool-up time before it reaches its full fire rate. Though the Arsenal lists a fire rate of 4.17, this is the fire rate before spool-up. Once fully spooled, the Grattler has a maximum fire rate of 6.25 rounds per second, 50% higher than its listed value.
The self-damage from explosions will only do 30% of the listed damage.
The innate punch-through prevents the explosion from occurring when hitting an enemy directly. The Grattler can only deal full damage if the shell hits a nearby surface, such as the ground, after piercing the enemy.
The Grineer text on the sides reads "Deth From Here".
The Grattler is the first Archwing Gun (and the first Archwing weapon overall) not to be of Tenno origin.
Not counting the Imperator or the Veritux (as well as the latter's Prisma variant), the Grattler is the first Archwing weapon that only uses resources for construction, as opposed to requiring weapon parts.
The Grattler's design and functionality appear to be modeled on several real-world Anti-aircraft guns, which can have multiple barrels for a high rate of fire and in earlier models would fire explosive shells to cloud the skies with shrapnel. This is further supported because associated files for the Grattler refer to it as "ArchGRNAAGUN," which can be seen as an abbreviation of "Archwing Grineer AA Gun".

Update 24.2 ‘ATMOSPHERE’ ARCH-GUN WEAPONS
It’s time we equipped some serious floor firepower! All Arch-Guns can be used on the ground - or as we like to call it ‘Atmosphere’ - with the use of a ‘Gravimag’. Gravimag is obtained from Clan Research, or as a one-time reward from the Orb Heist Phase 3 Bounty, and can be installed on any Arch-Gun (with an Orokin Catalyst installed) via the Upgrade Arsenal - similar to installing a Catalyst.
Comparable to the Archwing and K-Drive Launchers, a respective Gear item known as the Archweapon Deployer is required to activate your Atmosphere Arch-Gun. The Archweapon Deployer can be obtained by completing the Orb Heist Phase 3 Bounty.
Atmosphere Arch-Gun General Changes:
Atmosphere Arch-Guns consume Ammo as opposed to unlimited Ammo/Battery in Archwing. Specifically new Heavy Ammo Drops which can be found from Corpus enemies in Orb Heist missions. Heavy Ammo Drops also reset the 10 minute cool-down when picked up, or replenish Ammo if needed.
Atmosphere Arch-Gun can be summoned in normal missions with the Archweapon Deployer, but once Ammo has been depleted there is a 10 minute cool-down until you can summon again. The intent here is to allow you moments of beefy damage output, and not become just another Primary/Secondary weapon.
All stat changes are for Atmosphere Arch-Gun mode, Mastery Rank changes are global:
