In 2004, some three years into the Global War on Terror, Sergeant Bryan Kremer was sprawled out in the prone behind his Barrett M82A1 .50-caliber semi-automatic sniper rifle in the dusty hellscape that was early 21st-century Iraq. His spotter was arranged alongside behind a powerful optic of his own. The two men were surveilling a group of insurgents operating nearly a mile and a half away.
These two guys were deployed to Iraq with the 2d Battalion of the 75th Ranger Regiment. Kremer and his fellow Rangers were busy doing the Lord’s work in the aftermath of the 9/11 attacks. Once the rules of engagement were satisfied, his spotter lased the target one last time and Kremer set his dope. They took into account wind, air density, and mirage. These guys were fluent on the subjects of gyroscopic drift, angle to target considerations, and Coriolis & Eötvös Effects. Satisfied that all was as it should be, Kremer attended to his breathing, aligned his reticle, and squeezed.
The massive 671-grain Raufoss Mk 211 Class A match round exited the Barrett’s gaping harmonica-shaped muzzle brake at 2,800 feet per second. Several seconds later, that big honking bullet sent an Iraqi terrorist straight on to his date with those 72 dark-eyed virgins. Kremer and his spotter had just executed the longest successful sniper shot in American military history. The final GPS-verified range was 2,300 meters or 2,515 yards.
Death Dealing Down Under
Eight years later in 2012, two Australian 2d Commando snipers crouched behind matching Barrett semi-automatic .50-caliber sniper rifles equipped with Schmidt & Bender optics. Their quarry was a senior Taliban commander identified via pre-mission intel. This deep into the wilds of the Kajaki District in Helmand Province in Afghanistan, this notorious terror leader rightly believed himself invulnerable. These two Aussie snipers held a quick confab and made a plan.
They, likewise, pondered a dozen different variables that would invariably affect the flight of the heavy match bullets out of their hulking semi-auto precision rifles. When they felt they had the right moment, both snipers fired simultaneously. It took six seconds for the two rounds to traverse the 2,815 meters (3,079 yards) to the target. Having blown the Taliban commander quite literally to pieces, these Aussies had set yet another fresh long-range record despite there being two shooters who now shared it.
The Gun
The Barrett M82A1 rifle stretches 57 inches from muzzle to butt and weighs just shy of 33 pounds empty. This remarkable precision weapon is as long as a pool cue or a standard ironing board. It weighs as much as a mid-sized cinder block or a truck tire. Despite the fact that the barrel recoils back into the receiver upon firing so as to mitigate the big cartridge’s undeniably prodigious recoil, the rifle still offers shockingly precise long-range accuracy.
A personal friend who was issued a Barrett while serving as a sniper with the Ranger Regiment in Afghanistan didn’t care much for it. He said it was too long, too bulky, too heavy, and most importantly, too loud. As they typically humped their precision rifles up onto mountaintops to secure an optimal vantage, the gun’s generous dimensions and ample weight made that climb a proper butt whooping. The booming sound it made also reliably alerted the entire countryside that the Ranger snipers were out collecting scalps. However, that Barrett .50-caliber precision rifle nonetheless still did things that lesser weapons simply couldn’t.
Origin Story
Ronnie Barrett, the father of the M82A1 sniper rifle that bears his name, was not an engineer or a gunsmith. He never went to college or studied technical design. Ronnie was a professional photographer who was tasked to take some action photos of a Navy river patrol boat bristling with weapons. This was the first time he had ever seen a Ma Deuce .50-caliber machine gun up close. At the end of the day, he found himself intrigued with the thought of firing one of those gigantic half-inch anti-aircraft rounds from the shoulder.
Ronnie went home from that photo shoot and began sketching. The prevailing wisdom was that the .50 BMG round was clearly too large for a practical shoulder-fired weapon. However, Ronnie schemed out a way to harness physics and launch these hand-sized anti-materiel cartridges out of a semi-automatic rifle without brutalizing the shooter in the process. The basic action is philosophically similar to that of the Browning Auto-5 shotgun.
At the moment of firing, the bolt and barrel recoil briefly as a unit. Once they hit the rear stops, the two components disengage and the barrel returns forward under spring power to reset for the next round. The bolt continues rearward to eject the empty case and pick up a fresh example from the 10-round magazine on the way back into battery.
It took forever for Ronnie to find a machinist who would give him the time of day. However, tool and die maker Bob Mitchell accepted the challenge. Four months later, they had a firing prototype. The first .50 BMG round Ronnie Barrett ever fired was through his own experimental rifle.
Trigger Time
Firing the M82A1 is indeed a unique experience. The recoil is more a shove than a slap. Most folks liken it to a 12-gauge shotgun firing high-brass loads, and I would as well. The muzzle blast out the sides of that big muzzle brake will reliably clear your sinuses if you are stupid enough to stand close alongside at the moment of firing. Ask me how I know this …
The pistol grip and safety are standard AR-15 fare. There is a full-length Picatinny rail for glass up top and a rugged M60-style folding bipod. Despite the gun’s gargantuan dimensions and manly comportment, it indeed remains a precision instrument downrange.
Market Penetration
The CIA purportedly took out an ad in Shotgun News in the 1980s and subsequently bought their first batch to ship to the Mujahideen in Afghanistan for use against Soviet helicopters. Sweden’s was the first recognized military to field the big gun. American snipers first unlimbered the Barrett beast in anger in 1990 during the First Gulf War.
Nowadays, the big Barretts are everywhere. Fifty-four of the world’s 195 recognized countries utilize the Barrett M82 rifle operationally. They have also been famously employed for real by the Provisional IRA, Mexican drug cartels, the Houthis, and al Qaeda. Heck, I own one, and I’m just some dude.
Ruminations
Today, Uncle Sam uses an upgraded version of the M82, called the M107. Though technically classified as an anti-materiel rifle capable of knocking out light armored vehicles and combat helicopters, the gun is obviously capable of precision work when called upon to do so. Five of the world’s top 20 longest confirmed sniper kills were executed using Barrett M82 rifles. That’s not bad for a gun designed on the back of a metaphorical cocktail napkin by a professional photographer.
