This video tests the myth of water being bulletproof by firing various firearms, from 9mm handguns to a .50 BMG rifle, into a water tank. Results show that even high-powered rounds like the .50 BMG are significantly slowed or stopped by water, failing to penetrate to the target. The tests demonstrate water's effectiveness in dissipating projectile energy.

Mark Serbu, a gun designer, details the complex machining process for the BFG-50A trunnion, a critical component housing the serial number and barrel extension. He discusses challenges with tapping hardened alloy steel, including tap breakage, and the successful implementation of using a larger drill size with molybdenum disulfide grease. The video also covers thread milling techniques for various holes, including the gas cylinder boss, and highlights the importance of precise tolerances for accuracy.

This video demonstrates the advanced machining process for the BFG-50A rifle receiver, specifically focusing on creating the scope base holes. Gun designer Mark Serbu details the use of CNC machinery, touch probing, and specialized tooling like carbide center drills and 5/16 inch endmills to achieve precise tolerances on the complex weldment receiver. The process highlights the importance of accurate fixturing and the capabilities of modern machining for firearm manufacturing.

Mark Serbu discusses the challenges of manufacturing BFG 50A bolt carriers and other components, detailing a complex SolidWorks modeling process for a helical cam pin cutout. He also provides a public service announcement regarding firing pin retention in the BFG 50A and offers advice on removing a peened firing pin retainer. The video highlights the outsourcing of parts like bolt carriers and extractors due to production demands.

Mark Serbu discusses the development of a piston system for the BFG-50A, moving away from direct impingement due to alignment issues. He highlights the challenges of a stuck, corroded original piston system and introduces a new, smaller piston design. The video also showcases unusual bolt carrier bounce and hammer behavior observed during testing of the piston system, even without a return spring.

This video tests the durability of empty paintball CO2 tanks by shooting them with various firearms, ranging from .22LR to .50 BMG. The tanks demonstrate significant resistance to penetration from pistol calibers and even some rifle rounds, with only the largest calibers like .50 BMG consistently penetrating. The experiment highlights the robust construction of these tanks under ballistic stress.

This video provides a deep dive into the new aluminum extrusion handguard for the BFG 50A rifle, contrasting it with the original steel version. Mark Serbu explains the design evolution, focusing on the M-LOK attachment points, the innovative spoke tensioning system that uses bicycle spoke components and custom-made spokes, and the manufacturing process of the aluminum extrusion. The guide highlights the advantages of the new design in terms of manufacturing efficiency and modularity.

This video details the upgrade to a new aluminum extrusion handguard for the BFG-50A, replacing the previous steel weldment. The new handguard features M-LOK cutouts and a novel tensioning system utilizing high-tensile strength music wire, inspired by bicycle spoke principles. The speaker emphasizes the improved precision of the machined trunnion and the robust mounting method for accessories like bipods.

This video showcases an early prototype of the BFG-50A rifle, filmed in 2008 with no post-production. The description highlights unique design features, including a handguard latch mechanism and a modified trigger housing that shortened the firearm but presented engineering challenges. The footage also captures a failure to eject, attributed to potential undergassing in this pre-production model. It offers a glimpse into the development process of a specific large-caliber rifle.

This video tests the effectiveness of eBay-sourced Level IIIA armor plates against various high-powered rifle and handgun rounds. While the plates successfully stopped a .44 Magnum, they were completely penetrated by .50 BMG, 5.56mm, 7.62x39mm, and 7.62x51mm rounds, highlighting the limitations of Level IIIA armor against military-grade rifle threats.

This video highlights the appearance of the BFG-50A rifle in the Amazon Prime Video series "The Boys." The creator acknowledges a copyright violation but expresses enthusiasm for the show. They point out an inaccuracy in the video at 0:10 where a pistol's action sound is used instead of the BFG-50A's. The creator was alerted to the rifle's appearance by a friend, finding it unusual as they haven't sold any to Hollywood prop houses. The presence of the .50 BMG rifle is attributed to it being a Canadian production, given California's ban on the caliber since 2004.

This video from Edwin Sarkissian provides a unique ballistic test, evaluating how many Apple MacBook Pro laptops are required to stop various calibers of bullets, ranging from 9mm to .50 BMG. The experiment highlights the significant penetration power differences between calibers and ammunition types, offering a visual demonstration of terminal ballistics. Sarkissian's enthusiastic approach and clear explanations make complex ballistics accessible.
