SULFUR Knop .22 Build: Oils, Chisels and Attachments

The best Knop .22 build is a 5.56mm chamber chisel plus ammo-saving oils: the chisel raises damage from 120 to 160 per shot, and oils that lower ammo consumption let the single-shot breech rifle fire its full 480 RPM without consuming every round. That combination turns a slow, one-round hunting rifle into a hard-hitting pseudo-repeater, per the SULFUR community weapon wiki's caliber and oil notes.

How to build it

The Knop .22 accepts muzzle attachments, sights, laser sights, a gun crank, and chamber chisels. A community build calculator confirms any gun takes up to 5 oils (or 4 oils plus 1 scroll) and 5 attachment slots.

1. Chisel the chamber to 5.56mm

   A 5.56mm chisel changes the Knop from 120 damage in 9mm to 160 damage with 5 recoil (up from 3). A player guide on the game's Steam forums notes chisels, oils, and scrolls are what turn mid-tier guns into powerhouses, and the Knop's 1000 durability makes it "adequate to build" that way.

2. Layer ammo-consumption oils

   Oils that reduce or eliminate ammo consumption let the Knop fire at its full 480 RPM without spending the chambered round, which completely reverses its otherwise slow single-shot rhythm. On guns like this, a community YouTuber's gun-building crash course recommends the savior / bulk / keep trio (-40%, -40%, -20% ammo consumed) for true infinite ammo, or mosquito and Tetris oil as the classic two-oil core.

3. Add a scope or laser sight

   A sight or laser sight suits its long-range role; silencers reduce recoil and spread if you prefer a quieter option.

4. Pair it with a sidearm

   Its magazine is one round and the reload is slow at the breech, so carry a backup for close range.

Why this build works

The Knop has a x2.0 damage multiplier and 3000 durability, giving it one of the game's best damage-to-durability ratios — ideal for heavy modification and efficient ammo use. As a budget stand-in for snipers like the Rokua .308 or Dolphin 99, it one-shots Goblin Young to the head and kills Goblin Spearmen or Archers in two, and it is the highest damage-per-shot weapon chambered in 9mm by default. It is sold by Stiffleg for 1500 SulfCoins (wiki data, checked 2026-11-06).

FAQ

Is a 5.56mm chisel the best option for the Knop .22?

It is the strongest documented chisel for it, raising damage to 160 per shot. The wiki also mentions 7.62mm and 50 BMG chisels as options for players chasing sniper-level damage.

Can the Knop .22 get infinite ammo?

Yes — stacking ammo-consumption-reduction oils (savior, bulk, keep, or mosquito/Tetris variants) removes its ammo cost, though the exact oil values have changed across updates, so check current oil text in-game.

Where do I buy the Knop .22?

The community wiki lists Stiffleg as the vendor at 1500 SulfCoins, with a 750 SulfCoin sell value; it also drops reasonably often.

Check note: stats and attachment types come from the SULFUR community wiki's Knop .22 page and the SULFUR Build Calculator, with oil strategies from player discussions on Steam and a gun-building video guide; game context is from the official Steam page. Exact current oil values after the 1.0 patch remain unconfirmed.
