The M249 light machine gun (LMG), formerly designated the M249 Squad Automatic Weapon (SAW), and formally written as Light Machine Gun, 5.56 mm, M249, is the American adaptation of the Belgian FN Minimi, a light machine gun manufactured by the Belgian company FN Herstal (FN). The M249 became more or less a direct adaptation of the Belgian design with a few Army-requested changes to suit mission needs and American production methodology. The weapon was selected in 1982, introduced with the US Army in 1984 (the US Marines accepted the weapon in 1985) and, after an extensive period of testing common to most US military firearms, the M249 was finally delivered to frontline US Army forces in 1992. By and large, the M249 remains faithful to the overall form and function of the FN Minimi with the most notable change being the addition of a perforated heat shield at the barrel and a new butt. The heat shield protects the operator from accidental burns and also serves to minimize the effects of heat distorting the action as seen through the sights.
Like other modern infantry forces, the US military survives through various levels of specialists that benefit the whole. Base infantryman armed with their standard service rifles head the assault and these forces are supported by specialist troops armed with larger, heavier automatic weapons for suppression fire and direct contact of enemy forces. The M249 fulfills this role as a portable, voluminous fire design intended to support infantry actions at the squad level.
The US move to a more compact machine gun was born from a 1960s initiative which saw American ground forces tied to the cumbersome, rifle-caliber-chambered M60 General Purpose Machine Gun (GPMG) of the Vietnam War era and the Browning M2HB heavy machine gun system. As such, there proved a “bridge requirement” to bring about a more portable system chambered for the smaller 5.56mm NATO round via belt. The weapon would be crewed by a single operator for efficient management in the field and provide the needed sustained fire through a high-volume automatic action. While various experiments were conducted in the Vietnam War to find such a weapon, the solution would not come until well after the war in the 1980s with the settlement of the Belgian FN Minimi. The Minimi was successfully evaluated (as the XM249) beginning in 1974 against the Colt M16 HBAR and the Heckler & Koch HK23A1. Testing continued into 1981.
The M249 retains the general appearance and layout of the FN Minimi before it. The receiver is a large, rectangular block housing the required internal components. The stock is a webbed, twin strutted assembly affixed to the rear of the receiver in the usual way. The trigger group and pistol grip are underslung beneath the receiver. Ahead of the receiver is the forend/handguard shrouding a portion of the barrel and gas cylinder. A folding bipod assembly is fitted at the gas cylinder and collapses rearwards against it when not used. The barrel protrudes a short distance ahead of the forend and is capped by a conical slotted flash hider. Iron sights are provided over the receiver and midway along the barrel. A carrying handle is offset to the right side to facilitate transport and barrel changing. Ammunition is fed through a port along the left side (box or belt) and exits from the right. Sling loops allow use of a shoulder strap. The M249 can also be supported via the M192 LGM tripod assembly.
Production of American M249s is handled by FN Manufacturing Company of Columbia, South Carolina, USA. The initial batch of 1,100 M249s were built and delivered directly from Belgian factories and were marked as such. Since entering service as the “M249 SAW”, the system has been redesignated in 1994 to “M249 Light Machine Gun (LMG)”
The M249 has been manufactured or modified into several notable forms beyond the first generation base M249. The M249 PIP was an early Product Improvement Program form with a plastic stock replacing the original metal one. New sights were also added as was a new pistol grip, bipod and flash suppressor. Picatinny rail sections were eventually installed. The M249 PARA is a more compact version with sliding butt. The M249 Special Purpose Weapon is a compact SOCOM series version with weight reduction taken to the extreme – lacking the carrying handle, magazine well and vehicle mounting hardware. Another SOCOM type is the Mk 46 Mod 0 with Picatinny rail support and varying barrel options. The Mk 48 is yet another SOCOM breed following the Mk 46 Mod 0 though chambered for the larger rifle-caliber 7.62x51mm NATO standard cartridge.
Deranged mass shooters have long employed the lethal firepower of the AR-15, the popular civilian version of the military assault rifle that has been issued to U.S. troops since the Vietnam War. Early Sunday morning in Orlando, a hate-filled gunman armed with an AR-15-style rifle—a Sig Sauer MCX—stormed a crowded gay nightclub and killed 49 people and wounded more than 50 others in the deadliest mass shooting in American history before he was shot dead by a SWAT team.
Omar Mateen, 29, a New York-born shooter who had pledged allegiance to ISIS during a 911 call, reportedly equipped his semi-automatic rifle with a high-capacity magazine enabling him to fire dozens of bullets without reloading, Vocativ reports.
The controversial AR-15, which is famously America’s most popular sporting rifle with more than 12 million sold, is prized for its accuracy, speed, reliability and portability by hunters and target shooters.
But the civilian AR-15—which differs from the military version in that it can only be sold as a semi-automatic—has also been used in some the most high-profile murder sprees in recent memory.
Shooters armed with AR-15s have killed people in the following massacres, according to NBC News:
Dec. 2, 2015 — The AR-15 was one of the weapons Syed Rizwan Farook and his wife Tashfeen Malik used to kill 14 people and wound 22 more in an attack on the Inland Regional Center in San Bernardino, California.
Oct. 1, 2015 — Christopher Harper Mercer fatally shot and assistant professor and eight students in a classroom at Umpqua Community College in Roseburg, Oregon. He was armed with an AR-15 and other weapons.
June 7, 2013 —John Zawahri was armed with an AR-15 when he went on a rampage at the Santa Monica Community College outside of Los Angeles. He killed five people and wounded four before he was killed in a shootout with cops.
Dec. 14, 2012 — Adam Lanza used an AR-15 purchased by his mother to murder 20 first graders and six staffers at the Sandy Hook Elementary School in Newtown, Connecticut. He used a handgun to kill himself as the cops were closing in.
July 20, 2012 — The AR-15 was part of James Holmes’ arsenal when he opened fire during the midnight screening of “The Dark Night Rises” at a movie theater in Aurora, Colorado [killing 12 and wounding more than 70].
While many law-abiding gun enthusiasts will continue to advocate the AR-15 for hunting and shooting sports, the latest carnage in Orlando has unsurprisingly rekindled fierce debate about the AR-15 and other assault-style rifles.
Sadly, if history is any judge, it won’t be the last time the AR-15 or its widely-available ilk will be used in a horrific mass shooting.
Do you have plans of taking a shotgun with you when it comes time to grab the bug out bag and get out of dodge? I know that shotguns are not normally part of bug out plans due to their size and weight. Most of us are already packing our handgun and a rifle, no one has room for a shotgun.
Well with the introduction of the Chiappa M6 X-Caliber 12 gauge survival shotgun you can elect to leave your standard rifle and shotgun at home you choose to. It shoots 12 calibers of ammunition.
The rifle was originally designed to fire a 12 gauge shell and a .22lr, but with the X-Caliber adapter set the M6 can fire up to 12 different calibers including .380 , 9 mm , .357Mag/.38SP , .40 S & W, .44 Mag, .45 ACP , .410/.45colt, and 20 gauge.
The entire system is made of steel except for a foam insert in the butt stock to reduce weight. By pressing a single lever, the M6 can be folded at a hinge point to a compact 18″ that can easily fit in most backpacks.
