In this comparison of the Valmet M78 and FN Model D light machine guns, John Keene and Ian McCollum debate their military utility. Keene favors the FN-D for its quick-change barrel and robust design, while McCollum leans towards the Valmet M78 for its inherent reliability and lighter weight. Both experts acknowledge that soldier proficiency can overcome weapon limitations.

This video from Forgotten Weapons, hosted by Ian McCollum, provides an in-depth analysis of what determines a firearm's rate of fire and how it can be manipulated through design. McCollum, a recognized expert in historical firearms, explains the fundamental principles of bolt cycle time, bolt mass, and bolt velocity, and how these apply to different operating systems like simple blowback and locked breech. He illustrates these concepts with examples of various historical firearms, including the M11A1 and Chauchat, and discusses design modifications for rate adjustment.

This guide details the field stripping procedure for the FN Model D, a variant of the Browning Automatic Rifle. It covers accessing the internal components, including the unique gear-driven mechanical rate reducer responsible for controlling the cyclic rate. The FN Model D, designed by Dieudonné Saive, offers a quick-detach barrel and improved bipod compared to earlier BAR models.

This guide details the quick-change barrel demonstration of the FN Model D, as presented by experts from Brownells and Rock Island Auction Company. It highlights the mechanical lineage of the design, influenced by John Moses Browning's original BAR and leading to later models like the M240. The video emphasizes the advanced engineering for its time, including features like a quick-change barrel, adjustable gas system, and robust construction.

Ian McCollum of Forgotten Weapons provides an in-depth review of the Colt R75A, the final commercial variant of the BAR. He details its historical context, licensing disputes between Colt and FN, and unique mechanical features like its quick-change barrel system and dust covers. The R75A is presented as a refined and stable light machine gun, superior to the military 1918A2 in some aspects, despite its late arrival in the BAR's production life.

This Q&A session from Forgotten Weapons covers a range of firearms topics, including the mechanics of gain twist rifling and its applications, comparisons of various rifle cartridges, historical firearm decisions like the US adoption of the M1903 Springfield over the M1917 Enfield, and the design philosophy behind the AR-15. It also delves into the surplus market, collectible firearm acquisition, and the rationale behind certain firearm designs and their perceived reputations.
