This video provides an expert-level comparison of the Sig 550 series rifles against AK variants, drawing insights from a seasoned firearms instructor. It delves into the historical influences, mechanical similarities, and crucial design differences, including receiver construction and internal mechanisms. The analysis concludes that the Sig 550 series, while sharing some lineage, is a distinct firearm design and not an AK variant.

This video details the development of the AK-50 V3, a .50 BMG rifle based on the AK platform, by Brandon Herrera. It highlights the use of 3D printing for rapid prototyping of components like the receiver and bolt, focusing on design refinements for the V3 iteration including a bulged RPK-style receiver and a helical tri-lug bolt for improved reliability. The project emphasizes iterative design and testing to achieve a production-ready firearm.

This entry details the developmental journey of the AK-50, a .50 BMG AK-style rifle, as explained by its designer, Brandon Herrera. It covers the V1 prototype's challenges, including gas port failures and heat treatment issues, and highlights design solutions like the triangular bolt face, assist spring, and dual recoil spring system. Herrera's candid discussion reveals significant engineering hurdles overcome through iterative design and a deep understanding of firearm mechanics.

This video provides an in-depth look at the August 2020 progress of the AK-50 project, a custom rifle chambered in .50 BMG. Lead designer Brandon Herrera details the evolution of the rear trunnion, comparing it to AKM and PKM designs, and introduces a novel floating trunnion and buffer system. The update covers the transition to a stamped sheet metal receiver and outlines the next steps, including machining the bolt carrier and riveting the trunnions. Herrera emphasizes the self-funded nature of the project and the avoidance of pre-orders.

This video details the advanced gunsmithing challenges encountered during the final testing phase of the AK-50 V1 prototype. Lead designer Brandon Herrera transparently discusses issues like stacking tolerances, bolt galling, and magazine feeding, showcasing the iterative process of refining a complex firearm design. Lessons learned from the V1 are slated for implementation in the V3 production model, highlighting the dedication to engineering excellence.
