The TCR-18 (The Chuck Rifle - designed in 2018) is the current standard issue assault rifle for The Armed Forces of The Chuck since 2019, being the replacement model for the previous TCR-15.

The TCR-15 is still a very capable firearm, however The Chuckian government deemed a new weapon was required for their armed forces, which could take advantage of modern technology, to obtain increased accuracy, longer effective ranges and increased lethality.

The rifle was designed and is manufactured by McAllister Munitions Company in The Chuck and is much loved by its users due to its light weight, reliability, ease of maintenance and accuracy.

The first prototype was delived to the The Armed Forces of The Chuck in mid 2018, which then underwent gruesome Military Viability Tests. After serious testing and improvements from these findings, The Armed Forces of The Chuck commisioned the weapon into service, being more than satisfied with its performance.

The weapon has proven its reliability across a multitude of environments. From the frozen tundra of the far north to the tropical rain forests near the equator, even including desert landscapes.

Design details

Operating Mechanism

The TCR-18 is a selective fire, gas-operated weapon that fires from a closed bolt. It uses ignited powder gases channelled through a vent in the barrel to drive a long stroke piston located above the barrel in a gas cylinder to provide power to the operating system. The weapon features a self-regulating gas system and a rotary bolt breech locking mechanism (equipped with two locking lugs), which is rotated by a helical camming groove machined into the bolt carrier that engages a control pin on the bolt. Extraction is carried out by means of a spring-loaded extractor contained in the bolt and a protrusion on the left guide rail inside the receiver acts as the fixed ejector.

The reason that the firearm uses the 6.8×43mm (SPC) round and not the common 5.56mm Nato or 7.62mm round is the weight, accuracy, low-recoil and increased lethality benefits that it offers.

Features - Fire Selector

The weapon is hammer-fired and uses a trigger mechanism with a 4-position fire selector and safety switch. The stamped sheet steel selector bar is present on both sides of the receiver and its positions are marked with letters: "S"— indicating the weapon is safe, "R"—single-fire mode ("R" is an abbreviation for "repetition"), "B"- 3 Round Burst mode and "A"—fully automatic fire. The "safe" setting disables the trigger and secures the weapon from being charged.

Features - Rifle Stock

The TCR-18 is equiped with a folding stock, with the tail of the stock fitted with a light rubber buffer. This stock setup was designed to optimise accuracy and user comfort during the firing of the firearm. The stock is manufactured with lightweight synthetic material.

Features - User Handling

The firearm's pistol grip is made of a sturdy light weight synthetic material. The grip is molded, allowing the user better grip and comfort. Lastly it is covered with a nonslip material, to ensure accuracy and comfort even when the user's hands are wet.

The barrel rail also acts as the hand-guard, made from a lightweight and non-slip synthetic material. This again optimises accuracy, comfort and safety to the user.

Features - Feeding

The weapon is fed from a synthetic box magazine with a 35-round or 50-round cartridge capacity (designed to use the 6.8×43mm SPC cartridge) loaded in a staggered configuration. The spring loaded magazine can me dissassembled for easy cleaning and maintenance.

Features - Sights

The rifle has conventional iron sights that consist of a front post and a flip-up rear sight with 300m, 500 m and 800m apertures. The front sight is adjustable for windage and elevation and is also a flip up, allowing easy installation and use for various other optical sights. The rear sight is mounted to the Picatinny rail to the rear.

For nighttime use, the rifle is equipped with self-luminous tritium light dots (exposed after placing the rear sight in an intermediate position) installed in a pivoting bar to the front sight base, which folds up in front of the standard post and aligns with two dots in the rear sight notch.

Features - Barrel

The RAS (Rail Accessory System) allows the barrel to be Free Floating, and dual functions as a simple yet ergonomical hand grip (as mentioned in 'User Handling').

The match-grade cut barrel is manufactured from 410 grade stainless steel, and due to the Rail Accessory System, turns it into a free floating barrel, once again optimising accuracy. The barrel front end is slotted with a flash hider, with a barrel thread, allowing a optional surpressor to be added.

The RAS, encompassing the entire length of the barrel and body cover up to the rear sights, allows the add-on of a wide variety of accessories to the weapon, with ease and without the need of tools.

Features - Body

The rifle's stock, pistol grip, body cover, magazine, and RAS is manufactured from a durable light weight synthetic material, reducing overall weight. The only metal parts is the "internal working parts" and the barrel.

For regular field maintenance and cleaning, the firearm is disassembled into the following components: the receiver and barrel group, bolt carrier, bolt, return mechanism, gas tube, receiver dust cover and magazine.


The following accesories is issued with each weapon:

- Weapon Case
- Weapon Bag (All Terrain)
- 5 x 35-Round Magazine
- 2 x 50-Round Magazine
- Cleaning Kit
- Tactical 3-Point Weapon Sling
