The A-Zoom 7.7x58 Japanese Aluminium Snap Caps - 2 Pack is a dedicated, inert training and maintenance tool engineered specifically for firearms chambered in 7.7x58mm Japanese (7.7mm Arisaka). Each snap cap is precision CNC-machined from solid aluminium to match the exact exterior dimensions of standard factory ammunition, ensuring smooth cycling through internal magazines, bolt faces, and extractors. Fitted with a resilient synthetic "Dead Cap" polymer primer insert, these inert dummy rounds absorb firing pin strikes to prevent striker assembly wear, spring fatigue, and dry-fire damage during function testing, trigger practice, or long-term firearm storage.

Key Features:

  • Precision CNC-Machined Construction: Cut from solid aluminium to exact 7.7x58mm factory cartridge dimensions for reliable feeding and extraction without chamber shaving.
  • Hard-Anodised Finish: Durable hard-anodised red exterior resists rim chipping and allows immediate visual identification as inert dummy ammunition.
  • Dead Cap Polymer Insert: Synthetic primer insert absorbs firing pin impact to protect striker mechanisms across repeated practice sessions.
  • Extended Service Life: Primer insert is engineered to withstand over 3,000 dry-fire strikes before requiring replacement.
  • Function Testing & Storage: Facilitates safe magazine feeding, bolt cycling, and striker de-tensioning without using live ammunition.
