SAR West Gun Show!

This video from Legacy Collectibles announces their participation in upcoming gun shows in Phoenix, AZ (December 5-7) and Allentown, PA (December 6). The team, including new CEO Chris, will be present to accept consignment firearms. The speaker expresses personal satisfaction in remaining active with the company post-retirement, highlighting the community aspect of collecting.

This experiment tests the penetration depth of various sniper rifle calibers (.308 Win to .50 BMG) into hard-packed desert dirt. Results show significant differences, with smaller calibers penetrating only a few inches while larger rounds like the .408 CheyTac and .50 BMG reached depths of approximately 12 inches. A bonus test demonstrated the durability of a titanium Ridge Wallet against a .50 AE Desert Eagle.

This video demonstrates the destructive potential of a .50 BMG round and an M67 grenade on an oxygen tank in a truck bed. The initial .50 BMG shot caused a significant fireball and explosion, while a second shot and a grenade detonation resulted in severe structural damage to the truck. Remarkably, the Dodge Dakota remained operational after the ordeal.

This video demonstrates the extreme dangers of shooting pressurized oxygen and acetylene tanks in a truck bed using a .50 BMG rifle. The acetylene tank caused a massive explosion and fire, while the oxygen tank was propelled by its own gas release. The experiment also included testing an M67 grenade, highlighting the destructive potential of such scenarios.

This video demonstrates the extreme danger of shooting pressurized oxygen tanks. While smaller caliber rounds like 7.62x39 and 5.56 FMJ failed to cause significant damage, a .308 Winchester round ignited the released oxygen, causing combustion. The .50 BMG round resulted in a massive explosion, highlighting the severe risks involved. The content emphasizes that oxygen tanks are not safe targets and should never be shot.

This experiment tests the destructive potential of a .50 BMG rifle against an oxygen tank filled with propane. The .50 BMG round, specifically an armor-piercing 'black tip' variant fired from a Serbu BFG-50A, successfully ignites the propane in the oxygen-rich environment, causing a massive explosion and launching the oxygen tank. Damage assessment shows a significant impact hole but no clear exit, highlighting the extreme energy transfer.

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.
