Tapered barrel and receiver interfaces create a wedging fit that preserves bore alignment during thermal expansion, improving accuracy and reliability.
A preset-torque locknut and alignment fixture secure the barrel while minimizing torque transfer to the receiver and preventing misalignment.
A non-metal outer sleeve with matched thermal expansion keeps the barrel handleable after firing while preserving concentricity, rifling tension, and accuracy.
A slotted receiver, transversal screws, and a backup pin secure the replaceable barrel even when clamping screws are missing.
Segmented threaded fittings distribute mechanical stress along the barrel, preventing loosening and misalignment during firing.
Asymmetrical barrel feed ramps guide cartridges into the chamber with a gradual transition for reliable feeding.
A firearm housing bushing uses a clamping device to adjust slot width, enabling precise barrel root anchoring.
A split collar preloading device applies controlled force to firearm barrel threads.
Threaded receiver opening accepts interchangeable threaded and unthreaded barrels, resolving accuracy loss from play in unthreaded connections.
Mandrel-guided clamping mechanism prevents barrel warping and maintains accuracy without tool-based recalibration.
Merged barrel nut and suppressor housing support the barrel in tension while defining an annular chamber.
Segmented mount receiver, barrel sleeve, and collar enable rapid barrel exchange while maintaining fixation security.
A free-floating firearm barrel mounting system uses upper and lower securement fasteners to compress the barrel against the receiver.
A barrel retaining system uses locking lugs and camming notches to secure the barrel extension independently of the receiver.
Segmenting the gas piston assembly via a barrel nut adapter reduces residue accumulation and heat buildup in the bolt carrier group.
Cam clamp mechanism enables rapid barrel changes without specialized tools, preventing torque errors and scope misalignment.
Segmented alignment tab mediates receiver interface to resolve reliability versus interchangeability trade-off.
Segmented fastening prevents accidental detachment when transversal screws are missing.
Segmented quick-detach mechanisms allow users to swap handguards without compromising structural stability or barrel freedom.
A recoil lug key mates with a scope base pocket to lock the barrel and optic in tandem, preventing misalignment under vibration.
Elastic deformation of a crescent clamping piece enables adjustable barrel retention, resolving the trade-off between connection security and replaceability.
Oblique clamp faces on a barrel extension and mounting plate align the firearm barrel to the receiver, simplifying caliber changes without removing hand guards.
A multipart trunnion assembly uses a replaceable insert to secure a threadless barrel via an ambidextrous lug sleeve.
A quick-change firearm barrel uses multiple mounting features to enable secure attachment in various orientations without complex locking mechanisms.
A modular firearm barrel system uses universal threading and positioning slots to enable rapid caliber switching between AR-15 and Ruger 10/22 configurations.
A rifle barrel locking wedge uses a cam side to urge a barrel extension protuberance along the axis for secure seating.
Segmented barrel channels vent hazardous cartridge failure gases away from the user while maintaining firing reliability.
