The M79 Thumper: America’s Favorite Grenade Launcher

This video pits an LMT M203 grenade launcher against a watermelon, followed by rapid fire from a .50 BMG rifle. The M203's first shot missed, hitting a cinder block. The second shot hit the watermelon but failed to detonate. The .50 BMG then engaged the targets with rapid fire, demonstrating significant destructive power.

This video provides an in-depth look at the Heckler & Koch HK 33K rifle paired with an LMT M203 grenade launcher. It covers preparation of both 5.56mm M855 ammunition for the rifle and 40mm M781 practice grenades for the launcher. The demonstration includes live fire of the HK 33K and a functional test of the M203, showcasing the combined tactical capabilities of this military firearm setup.

The M79 'Thumper' grenade launcher is a break-action, single-shot weapon designed to extend squad reach beyond hand grenade range, effectively covering 50-400 meters with its 40x46mm low-pressure rounds. Its rifled barrel ensures accuracy, and it utilizes a High-Low pressure system for manageable recoil. The M79 features a simple automatic safety and inertial arming projectiles for enhanced operational safety.

The M79 'Bloop Tube' was a post-WWII development intended to provide infantry with a portable, accurate grenade launcher, replacing the bazooka. Its core innovation was the 40x46mm low-pressure system, adapted from German Rheinmetall High-Low pressure technology, enabling a lightweight design. Despite its success in Vietnam, its single-shot nature led to the development of under-barrel launchers like the M203.

This RECOILtv Gun Room episode features Iain Harrison showcasing the B&T GL06 Grenade Launcher. The video highlights the launcher's simplicity, B&T's renowned quality, and its lightweight, quick-deployment design. It emphasizes the supporting SIR (Safe Impact Round) ammunition family, designed for less-lethal applications in peacekeeping and law enforcement. The description also playfully suggests its utility against advancing armies. The video promotes the RecoilTV app available on various streaming platforms.

The Colt XM-148 was the US military's first under-barrel grenade launcher, developed from the SPIW program for the M16 rifle. Despite its innovative design, it suffered from significant flaws, including a snagging trigger bar, high cocking force, and mechanical complexity. These issues led to its replacement by the simpler and more reliable M203, making the XM-148 a notable but ultimately unsuccessful footnote in firearms history.

This video tests the 'magic bullet' theory surrounding the JFK assassination using a 6.5 Carcano rifle and a ballistic skull. Recovered bullets showed less deformation than expected, challenging assumptions about the original evidence. The test highlights the unpredictable nature of bullet performance after impact.

This video tests a Pedersoli Baby Philadelphia Derringer replica, the type used by John Wilkes Booth to assassinate Abraham Lincoln. The test demonstrates the .45 caliber black powder pistol's surprising close-range power, capable of penetrating a beverage can and causing significant fragmentation in a ballistic dummy head. The analysis compares the impact to historical accounts of Lincoln's skull fragments, highlighting the effectiveness of historical firearms.

This video compilation highlights critical firearm safety failures, emphasizing the dangers of ignoring basic rules. It features incidents like accidental discharges due to poor recoil management on revolvers and unsafe reholstering practices. The content serves as a stark educational tool, warning against dangerous internet trends and reinforcing the importance of responsible gun handling to prevent life-altering injuries.

This video analyzes the assassination attempt on Donald Trump by replicating the shooter's AR-15 setup and the Secret Service's counter-shot. It debunks conspiracy theories by demonstrating the difficulty of the initial shot and the terminal ballistics of both the attacker's and defender's rounds using high-speed footage and ballistic dummies. The analysis emphasizes that a precise ear-only shot from that distance with the described rifle is highly improbable.
