Locking block accessory mount engages the receiver assembly and provides a barrel engagement surface to maintain sighting accuracy despite tolerance stack-up.
A combination socket adapter engages barrel nuts and castlenuts using specialized gripping surfaces to apply torque with standard wrenches.
A ring-shaped barrel bushing biases into a slide cone feature to guide reciprocation without forward rails.
Segmenting the striker mechanism into a separate housing eliminates intricate slide machining, reducing manufacturing complexity and cost.
Indexing pins align hand guard while concealed set screws prevent loosening during firing.
A lift cap and locking pin mechanism allows quick pneumatic assembly removal while a spring-loaded plunger safely vents compressed gas during extraction.
Nested forend assembly protects the muzzle from damage during storage while maintaining full barrel length for legal compliance.
Extending the barrel tenon length and adding multiple anchor points eliminates interference fitting misalignment.
