不知火商店 (Shiranui)

Shiranui (不知火商店) is a Japanese maker best known for its Kagerou (陽炎) series of programmable electronic triggers, with versions for Version 2 gearboxes, Tokyo Marui next-generation rifles, P90 and AUG bullpups, the Type 89, M14, AK-pattern guns, ARCTURUS microswitch gearboxes, electric pistols and G&G ETU guns, plus its own SAIUN trigger line sold only through its webshop. The Kagerou 12 Type H replaced the earlier 12-series boards in September 2026. Shiranui also builds complete electric and gas guns fitted with its triggers, sells hop packings and other tuning parts, and repairs and installs its own boards, taking jobs and trade orders through its official LINE account.
