Loose Chamber

Conclave shotgun handling mod

Released Jun 4, 2015

Loose Chamber is a Conclave shotgun mod that trades increased recoil for faster reloads: at maximum rank it gives +30% Reload Speed and +50% Weapon Recoil. Consider it when reload speed matters more to your shotgun setup than recoil control.

Understand Loose Chamber

Useful when…

  • Reducing reload downtime in a Conclave shotgun setup.
  • Using a Naramon-polarity shotgun mod slot when the recoil increase is acceptable.

What changes in handling?

At rank 0 the mod gives +5% Reload Speed and +8.3% Weapon Recoil; rank 3 gives +20% and +33.3%; rank 5 gives +30% and +50%. The reload benefit comes with a substantial recoil increase, so the trade is most relevant when recoil remains manageable for your weapon and aim.

Slot, restrictions, and comparisons

Loose Chamber is a standard-slot Conclave shotgun mod with Naramon polarity and base drain 4. It is explicitly incompatible with Hydraulic Chamber and Loaded Capacity. Hydraulic Chamber reduces recoil by 60% but reduces magazine capacity by 10%; Loaded Capacity increases magazine capacity by 30% while reducing reload speed by 15%. These offer different handling trades, rather than interchangeable benefits. Accelerated Blast is a Standard shotgun mod with fire-rate and Puncture bonuses, not the same Conclave reload/recoil effect.

Rank investment and source

The mod reaches rank 5. Listed rank-up costs are 10 Endo and 483 Credits from 0 to 1, 40 and 1,932 from 2 to 3, and 160 and 7,728 from 4 to 5. Rank increases improve reload speed but also raise recoil, so stop at a rank where the handling cost remains acceptable. The listed source is Conclave, Mistral.

Limitations and tradeoffs

  • Faster reload comes with increased weapon recoil.
  • The supplied incompatibility list excludes Hydraulic Chamber and Loaded Capacity.

Common mistakes to avoid

  • Do not focus on reload speed while ignoring the matching recoil increase.
  • Do not try to equip it with Hydraulic Chamber or Loaded Capacity.
