Cartridge Extractors TRIZ Cases
- AR15 Cartridge and Bolt Modification for CQB Stopping Power
A modified .308-caliber AR15 cartridge and enlarged bolt raise stopping power while limiting overpenetration for close-quarters use.
- Firearm Bolt and Gas Tube Design for Delayed Unlocking
Delayed bolt unlocking, gas metering, and a heat-radiating gas tube reduce leakage, overheating, and cyclic rate instability.
- Recessed-Primer Blank Cartridge and Bolt Interlock for Firing Prevention
A recessed primer matched to a breech-face boss lets blank cartridges chamber only with the correct bolt, preventing firing in mismatched rifles.
- Shotgun Ejector Assembly With TAG Mounting for Field Repair
A TAG base and spring assembly replaces riveted shotgun ejectors to prevent breakage and enable screwdriver-based field repair.
- Caseless Ammunition Geometry for Delayed Self-Ignition and Extraction
A stepped shell geometry and expanding ring or magnetic extractor delay cook-off in heated firearms while improving caseless round extraction.
- Break-Barrel Extraction Assembly for Selective Shell Ejection
A movable retention element lets a break-barrel extractor fully eject spent casings while only partially lifting unfired rounds for manual removal.
- Modular Breech Block Bolt Head for Caliber and Ejection Changes
A standardized bolt head with detachable bezel parts adapts to different calibers and ejection directions without replacing the full breech block head.
