Attachments and Chamber Chisels: slots, removal and calibers

A gun holds one attachment from each of four categories: muzzle, sight or scope, laser, and chamber. To swap one, pay at Ralphie’s Workbench beside the Church to remove the old one first; you get it back. Attachments do not use enchantment slots. A Chamber Chisel is a one-time kit that rebores a gun to another ammo type. Every attachment’s stats are in the weapons list.

Attachment categories

Category	What it changes	Examples
Muzzle	Recoil, spread, bullet speed; silencers trade RPM for crit chance	A12C Muzzle Brake −35% recoil; Barrel Extension 6” −50% spread, +40% bullet speed, −20% move speed
Sight	Crit chance while aiming, zoom	Sniper Scope +30%, Hunting Scope +25%, Reflex Sight +15%
Laser	Accuracy while moving +50%	All colours are identical except Gold, which adds +20% crit chance
Chamber	Fire mode	Gun Crank makes a gun automatic; Priming Bolt makes it semi-automatic with +10% damage

Insurance also goes on a gun like an attachment; see death and Insurance.

Gun Crank does not raise fire rate

The Gun Crank lets you hold the trigger, but a pump or lever gun still cycles at its own RPM. On a Mossman or Bronco it saves clicking, not time. It pays off on fast semi-automatic guns and with gear that boosts automatic weapons, such as the Square Glasses (+10% automatic weapon damage). The Priming Bolt does the opposite and saves ammo and durability on guns that empty too fast.

Chamber Chisels

A chisel changes the ammo a gun fires. Damage, recoil and spread follow the new caliber. Energy weapons cannot be chiselled. Ralphie stocks all five; since 1.0.2 the 12Ga and .50 BMG kits appear more often, and since 1.0.1 the 12Ga kit’s base price is 7,500 instead of 15,000.

The Socom 9 pistol shows what each chisel does to one gun:

Ammo	Damage	Projectiles	Spread	Recoil
9mm (stock)	60	1	2	2
5.56mm	80	1	2	5
7.62mm	100	1	2	10
.50 BMG	200	1	2	40
12Ga	20	8	7	30

A .50 BMG chisel more than triples the Socom’s damage per shot but gives it twenty times the recoil; a Priming Bolt or recoil oils keep it controllable. Class multipliers carry over, so a revolver (×1.6) or sniper rifle (×2) gains more from a heavier round than a pistol does.

Chisels and oils

• On 12Ga, flat damage oils are divided by 8 since 1.0. A gun chiselled to 12Ga wants percentage damage oils.
• Experienced players pair flat damage oils with 9mm and Energy Cell guns, and percentage oils with 7.62mm and .50 BMG, because a flat +30 is half the base of a 9mm round but a sixth of a .50 round.
