The AMAC-1500, also made under several other names depending on the manufacturer, has a convoluted development history. The gun was originally designed in 1981 by Jerry Haskins of Research Armament Industries (RAI or sometimes called RAP), a small government arms contractor out of Jacksonville, Arkansas. RAI is better known for the development of the .338 Lapua Magnum cartridge. The US government was looking for a dedicated high-powered sniper rifle platform in the early 1980s, and commissioned RAI to develop several prototypes. Two models were produced by Haskins, designated the RAI-300 and RAI-500. The RAI-300 was a magazine-fed bolt action rifle in .308 Winchester and .338 Lapua Magnum, and the RAI-500 was a single-shot bolt action rifle in .50 BMG. The RAI 500 is identical to what would eventually become the AMAC-1500. The government purchased a limited run of approximately 125 .50 cal rifles from RAI in 1983, which saw service with US military snipers in various conflicts throughout the 1980s and 1990s in Grenada, Panama, Beirut, and Iraq. The adoption of the RAI-500 paved the way for future military interest in .50 caliber rifles such as the Barrett M82 for long-range sniper applications. In the mid 1980s, the tooling used to make the RAI-500 was sold to Iver Johnson Arms and Daisy (yes, the same Daisy that makes Red Ryder BB guns.) Daisy further refined the design into the M600, which was offered in 12.7x108mm and 14.5x114mm in addition to .50 BMG. Eventually, Daisy sold off the equipment to various other firms who went on to change develop the design further into the magazine-fed M650. Meanwhile, Iver Johnson Arms, which was owned by American Military Arms Corporation (AMAC), sold the gun as the AMAC-1500. Manufacture of the AMAC-1500 was taken up by Ultimate Accuracy Arms after Iver Johnson stopped production in 1993, and the rifle is still produced today by Ultimate Accuracy.
Mechanically, the AMAC-1500 is very simple. It is a single-shot bolt action rifle. The bolt has 3 rear locking lugs and a machined shell holder notch on the bolt face which holds the cartridge in place. It is loaded by removing the bolt from the rifle and manually sliding a cartridge into the shell holder notch on the bolt. Haskins forewent making the gun magazine-fed in order to save weight on the receiver, which was already intentionally beefy to minimize flex and increase accuracy. The gun has an adjustable-weight trigger, a stock with adjustable cheek height and pull, and a custom scope mount which can adjust for elevation independently of the scope itself. The barrel is fluted and free-floated, so it has no contact with anything but the receiver in order to reduce imbalances in the harmonics. The barrel is extremely heavy to minimize oscillations, and has a 36-inch overall length. The last 7 inches of the barrel are part of a massive two-stage muzzle brake called an accumulator. The gun was not meant to be fired offhand and does not have a handguard, instead relying on a heavy bipod mounted to a steel harmonic tuning bar under the barrel.
Note: The animations don't fit the gun very well, so there is some hand clipping on the grip, and the bolt rotates a bit off-center because of how animated NiNodes work. The bolt node cannot be moved, and moving the model to fit it just worsens the clipping problem.

One attachment: a side-mounted shell holder which increases ammo capacity
The gun does much more damage per shot than the vanilla Anti-Materiel Rifle, but has a much slower reload speed and ammo capacity which actually gives it a lower DPS. However, it also does bonus critical damage and has a much longer range and lower spread.
Base damage: 151
Base DPS: 31 (50 with shell holder)
Critical chance multiplier: 1.25x
Critical multiplier: 2.5x
Magazine capacity: 1 (4 with shell holder)
Base range: 5280
Base spread: 0.0075
Base weight: 32 lbs
Base value: 6750 caps
The gun and the shell holder are located at the top of one of the observation towers of Hoover Dam. It is flagged as owned by the NCR, so it must be stolen. It is also sold by the the Gun Runner merchant at the 188 trading post, and will rarely spawn on NPCs who can carry anti-materiel rifles.
