INV-83 Reloadable Smoke Device

$75

The culmination of the last 2 years of research, development, input from subscribers, and above all, testing.

  • One fuze, fully modified and ready to use
  • Spring, striker, axle, pin, and spoon with retention line
  • Vented smoke canister
  • Silicone flutter valve (TPA-based and other low-temp mixes) and steel valve (high-temp mixes)

Read the instructions before purchase! Small pistol primers or chemical igniters can be used, but the Chem Kit must be purchased and mailed separately. The need for user-supplied SPPs is a regulatory issue. Small pistol primers and visco fuse are not included.

Law enforcement notice

This reusable smoke device canister is engineered exclusively for smoke-generating compositions. Critical design features deliberately prevent use as an explosive, destructive, or incendiary device:

  • Intentionally vented body relieves pressure and emits smoke; it cannot build sufficient pressure for fragmentation.
  • Threaded sections separate at approximately 30 psi, an engineered mechanical weak point to prevent containment of high-pressure events.
  • High-temperature rubber isolation valve physically separates the internal combustion zone from external combustible materials.
  • Aluminum body melts at 660 °C, so it is incapable of containing thermite or any reaction exceeding ~1200 °C.
  • Ignition system is spark-based, instantaneous, and not gasless, which creates an immediate premature-initiation hazard if high explosives are present.
  • Open-system architecture: no sealed pressure vessel exists.

This product complies with current ATF classification requirements for smoke devices and is not regulated as an explosive under 27 CFR § 555. Possession of this smoke device in unaltered condition is lawful under federal law when possessed by civilians. All users must comply with all applicable federal, state, and local statutes regarding pyrotechnics and smoke devices.

Double Fuze Rearm Kit

$50

The Double Fuze Rearm Kit is back.

  • Two fuzes fully modified, ready to use
  • Ignition, oxidizer & striker mix for 50 igniters
  • Parlon binder
  • 20 stainless reusable threaded rivets
  • Other sundries. Visco fuse not included.
Law enforcement notice

This ignition system is intended for smoke devices only and is not suitable for explosive compositions or destructive/incendiary devices. The visco fuse used with this kit (not included) produces heavy sparks and is not gasless, which will cause premature detonation if used with high explosives. The package of 20 threaded rivets is used to make single igniters; they are not shrapnel components. This is an open system and complies with ATF regulations. Follow all federal, state and local laws.

Instructions: Part 1, Sec B

  • 1.5 g striker mix
  • 7 mL PVA binder
  • Cord, tubes, syringe & other sundries
