Introduction

The SUB-2000 is a pistol-caliber carbine manufactured by Kel-Tec CNC Industries of Cocoa, Florida, United States. The rifle is a blowback-operated, semi-automatic firearm with its operating spring located in the tubular stock.

The weapon feeds from a grip-located magazine well, using magazines designed for popular models of various other manufacturers’ handguns, and is an inexpensive carbine. The distinguishing characteristic of this rifle is that it folds in half, for storage and transportation, and its slim profile compared to other rifles.

It is available in two versions chambered for 9 mm or .40 S&W caliber cartridges. It was designed by George Kellgren, a Swedish-American designer who also designed many earlier Husqvarna (in Sweden), Grendel, and Intratec brand firearms, including the famous TEC-9 handgun.

The receiver is made of an impact-modified glass-reinforced Zytel. The front end houses a hinge block holding the barrel and the rear sight. This block is securely locked in place by a swiveling trigger guard. The receiver rigidly attaches to the stock by multiple lugs. The bottom of the receiver forms the pistol grip, also accepting different magazines according to the version specified. The receiver also houses the firing mechanism. The 4130 ordnance steel barrel has a spring-loaded collar to ensure an accurate lock between the receiver and the polymer fore-end and the fully adjustable front sight. The fore-end also has integrated the ability to house batteries and/or other small devices. The tubular steel stock contains the bolt and is ended by the polymer buttstock. The heavy two-piece steel bolt holds the firing pin, and the extractor and has the operating handle on the bottom. A captive guide recoil spring with a buffer actuates the bolt. The firing mechanism is of conventional single action type. It has a positive disconnector, and a push bolt safety that blocks the sear and disengages the trigger bar. The hardened steel ejector is internal. This design, with its long bolt travel, allows for very large functioning marginals.

The basic SUB-2000 design is implemented in a rather unusual folding design that folds for storage into half its total extended length. Folding is accomplished by pulling downward on the trigger guard and swinging the barrel assembly back over the top of the rifle. A latch in the buttstock secures the front sight housing, and the gun can be locked with a key in the folded position for added safety. The gun cannot be fired when folded.

At the 2007 SHOT Show held in Orlando, Florida, Kel-Tec introduced a series of new “High-Efficiency Rifles” called the RFB, standing for “Rifle, Forward-ejection, Bull-pup.” The RFB is a gas-operated semi-automatic rifle with a tilting breech block locking mechanism, loads the 7.62×51 NATO cartridge and uses metric FAL magazines; the RFB “family” consists of a series of Bullpup rifles with three barrel lengths (18″ barrel carbine, 24″ sporter and 32″ target versions), and a patented forward-ejection system via a tube placed over the barrel that ejects the spent case forwards, over the handguard of the rifle. This eliminates a major drawback of Bull-pup rifles, which is that they may not be readily usable by left-handed shooters. Distribution of the RFB rifles in the USA was scheduled for February 2009; as of 2013, it has been publicly released for sale. As a further Revolution of the Bullpup, the RDB (Rifle Downward-ejecting Bullpup) was released in late 2015.

The Glock pistol has a relatively low slide profile, which holds the barrel axis close to the shooter’s hand and makes the pistol more comfortable to fire by reducing muzzle rise and allowing for faster aim recovery in rapid firing sequences. The rectangular slide is milled from a single block of ordnance-grade steel using CNC machinery. The barrel and slide undergo two hardening processes prior to treatment with a proprietary nitriding process called Tenifer. The Tenifer treatment is applied in a 500 °C (932 °F) nitrate bath. The Tenifer finish is between 0.04 and 0.05 mm (0.0016 and 0.0020 in) in thickness, and is characterized by extreme resistance to wear and corrosion; it penetrates the metal, and treated parts have similar properties even below the surface to a certain depth.

The Tenifer process produces a matte gray-colored, nonglare surface with a 64 Rockwell C hardness rating and a 99% resistance to salt water corrosion (which meets or exceeds stainless steel specifications), making the Glock particularly suitable for individuals carrying the pistol concealed as the highly chloride-resistant finish allows the pistol to better endure the effects of perspiration. Glock steel parts using the Tenifer treatment are more corrosion resistant than analogous gun parts having other finishes or treatments, including Teflon, bluing, hard chrome plating, or phosphates. In 2010, Glock switched from the salt bath nitriding Tenifer process to a not exactly disclosed gas nitriding process. After applying the nitriding process, a black Parkerized decorative surface finish is applied. The underlying nitriding treatment will remain, protecting these parts even if the decorative surface finish were to wear off.

A fourth-generation Glock 17 consists of 34 parts. For maintenance, the pistol is disassembled into five main groups: the barrel, slide, frame, magazine, and recoil-spring assembly. The firearm is designed for the NATO-standard 9×19mm Parabellum pistol cartridge but can use high-power (increased pressure) +P ammunition with either full-metal-jacket or jacketed hollow-point projectiles.
