Videos tagged with Front Trunnion

This video details the completion of the AK-50 V3 parts at Titans of CNC, showcasing the precision machining of the bolt, bolt carrier, and front trunnion. It highlights the advanced 5-axis CNC capabilities required for the complex .50 BMG platform, including helical locking lugs and a two-piece bolt carrier design. The collaboration emphasizes the importance of verifying designs with 3D prints before committing to steel.

Brandon Herrera provides a detailed update on the AK-50 project, showcasing significant revisions to critical components. The front trunnion has been redesigned for improved bolt carrier function and headspacing, while the bolt carrier now features a modular cam groove inspired by the Stribog for easier prototyping. The recoil system is transitioning to a single-spring design with a rear booster for enhanced reliability under high pressure.

Brandon Herrera provides an update on the AK-50 project, detailing a significant design shift to a stamped receiver for improved aesthetics, weight, and manufacturing efficiency. The video showcases the prototype front trunnion with PKM-sized rivets and the use of 3D-printed dies for rapid prototyping of receiver dimples. The project is currently on version 7, emphasizing a budget-conscious approach to building a .50 caliber rifle.

This video details a dangerous experiment testing an AK-47 front trunnion without rivets, relying solely on receiver dimples. While dimpling creates a mechanical lock, the experiment ultimately fails catastrophically, demonstrating rivets are essential for structural integrity. The video also provides insights into AK construction and teases an AK-50 update.

This expert-level review by AK Operators Union, Local 47-74 provides an in-depth look 'under the hood' of the Palmetto State Armory PSAK47 Gen 2. The inspection highlights the rifle's billet-made components, including the front trunnion and bolt, and assesses the quality of rivets and assembly. The video details a partial disassembly, focusing on the recoil spring, trigger group, and bolt carrier, while also noting minor factory imperfections like a loose safety lever and un-tightened muzzle brake. The review sets the stage for a rigorous 5,000-round test.
