Last Video of 2024!

This video documents the creator's return to the SHOT Show in Las Vegas after a five-year absence. The primary focus is supporting Miller Precision Firearms, who will be producing the creator's "long-forgotten SU-15 upper." Beyond that personal connection, the video promises a look at "really cool stuff" seen at the event. The content appears to be a general overview of new products and experiences from the SHOT Show, with an emphasis on firearms and related industry developments.

This video discusses the potential revival of the "SU-15" firearm project. The creator designed an upper receiver in 2013 but was unable to bring it to market due to company size. After 11 years, a machinist has discovered the design and intends to pursue its production. The video expresses hope for the SU-15's future availability, linking to other SU-15 related videos.

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.

This video conducts a unique barrier test, using flour bags to stop various high-caliber rifle rounds. It demonstrates that 125 lbs of flour (5 bags) are needed to stop a .50 BMG round, while a 6.5 Creedmoor requires 100 lbs (4 bags), and a .338 Lapua Magnum needs 75 lbs (3 bags). The experiment concludes with a grenade detonation among the flour bags.

This video demonstrates the destructive power of a .50 BMG API round against six stacked Ozark Trail cast iron skillets. The experiment reveals that even multiple layers of cast iron are no match for this heavy caliber ammunition, with the skillets being completely obliterated. The content highlights the extreme ballistics of the .50 BMG round and the limitations of common materials against such force.

This video tests the ballistic resistance of a 1.5-inch thick titanium plate against various .50 caliber rounds, including Raufoss, APIT, and AP. While the rounds cause significant surface damage and craters, the titanium plate successfully withstands the impacts without bulging, demonstrating its impressive strength against high-caliber threats.

Mark Serbu details the complex process of converting a CNC lathe into a 12-barrel blank-firing machine gun. The project highlights the critical role of a lathe's C Axis for precise rotational control and the application of PID control theory to overcome initial firing failures. Modifications were made to ensure the device fires blanks only, avoiding legal issues.

This video demonstrates how to rifle a barrel in a home shop using basic tools, bypassing expensive CNC equipment. It covers material preparation, precise drilling and reaming, and the critical process of pushing a rifling button. While a DIY approach is shown to be possible, the video highlights the significant difference in quality and precision achievable with professional CNC machining.

This video provides an in-depth analysis of the Serbu RN-50 rifle that experienced a catastrophic failure during a Kentucky Ballistics test. Mark Serbu, the designer, meticulously examines the damage, noting severely bent steel side plates, sheared-off breech cap ears, and a sheared pivot pin. The inspection also covers the breech cap's condition, barrel threads, and the stuck casing, revealing a case head separation.

Mark Serbu, designer of the RN-50, addresses a catastrophic failure experienced by Kentucky Ballistics. He reassures customers about the RN-50's safety, attributing the incident to counterfeit or over-pressured ammunition. Serbu highlights the rarity of such events and emphasizes industry transparency, noting that his company has produced approximately 1,400 RN-50s since 2016 with hundreds of thousands of rounds fired without issue.
