Breech Mechanisms TRIZ Cases

A buffer assembly uses a counterweight spring to bias movement and delay the firing cycle.

Segmented modular components allow a single receiver to support suppressor integration and electro-optical sight mounting without increasing device complexity.

A bolt assembly uses a bias spring to drive the rotating head into the closed position.

Lateral apertures in the gas tube enable cleaning access and cooling while a notch configuration facilitates automatic bolt locking.

Rotating barrel action cycles via gas pressure to unlock lugs, enabling reliable operation of low recoil impulse cartridges.

Slanted baffles and coaxial spacers create expansion chambers that dissipate propellant gas energy, eliminating the need for absorbent meshes.

A self-releasing latch uses a roller mechanism to hold a firearm charging handle securely, reducing receiver wear and enabling ambidextrous operation.

A biasing device uses a spring to urge firearm receivers into firm contact with coupling pins, eliminating rattling caused by manufacturing tolerances.

A scissor-style bolt action mechanism allows the firearm bolt to remain stationary during firing.

Segmented modular components allow caliber swapping while maintaining receiver universality for diverse hunting scenarios.

A captured spring assembly encircles a guide rod with a buffer to absorb recoil energy and dampen mechanical oscillation.

A firearm operating system uses a sliding carriage and Belleville springs to store recoil energy for reliable cycling.

Spring-loaded pins engage receiver tube apertures to adjust stock length, eliminating the need for continuous lever engagement during extension or retraction.
