STYER AUG RIFLE SUBMITTED BY GENO I posted two variations of this rifle because there are several variations of this rifle to perform many different tasks.
Caliber: 5.56mm NATO (.223rem)
Technical description. AUG is built around the aluminium casting receiver, with steel reinforcement inserts. One such insert is used to provide the locking to the removable barrels and the rotating bolt, thus relieving the receiver from most of the firing stress. Other inserts are used as a bearings for the bolt carrier guide rods. The AUG uses a short piston stroke, gas operated action, with the gas piston mounted inside the compact gas block, which is fixed to the barrel. The gas cylinder is offset to the right from the barrel. Gas piston has its own return spring, contained inside the gas block. The gas system features a three positions gas regulator, which allows for two open positions (for normal and fouled conditions) and one closed position (for launching the rifle grenades). The gas block also contains a barrel fix / release lock and a front grip hinge. Each barrel has eight lugs, that lock into the steel insert in the receiver, and there's four basic barrel patterns for the AUG: standard rifle barrel is 508 mm (~20 in) long. "Compact" or "Submachine gun" barrel is 350 mm (13.8 in) long, "Carbine" barrel is 407 mm (16 in) long, and the heavy / LMG (light machine gun) barrel is 621 mm (24.4 in) long. On each rifle barrels can be exchanged in the matter of seconds. Each barrel is fitted with the flash hider, and the heavy 621 mm barrel also is fitted with lightweight folding bipods. There's no bayonet lug on Austrian service rifles, but it can be installed if required.
The bolt system consists of the bolt carrier, which has two large hollow guide rods, attached to its forward part. The left rod also serves as a link to the charging handle, and the right rod serves as the action rod, which transmits the impulse from the gas piston to the bolt carrier. The rotating bolt has 7 locking lugs, claw extractor and a plunger-type spring loaded ejector. Standard bolt has its extractor on the right side, to facilitate right-side ejection, but the left-side bolts (with mirrored positions of extractor and ejector) are available for those who need left-side ejection. The two return springs are located behind the bolt carrier, around the two string guide rods, that are located inside the bolt carrier guide rods. The cocking handle is located at the left side of the gun and normally does not reciprocate when gun is fired, but it can be solidly engaged to the bolt group if required by depressing the small button on the charging handle. On the latest AUG A2 variant, the charging handle was made folding up and of slightly different shape. The AUG action features a bolt stop device, that holds the bolt group open after the last round of ammunition from the magazine is fired. To release the bolt after the magazine replacement, one must pull the charging handle. The hammer unit is made as a separate assembly and almost entirely of plastic (including the hammer itself). Only springs and pins are steel. The hammer unit is located in the butt and is linked to the sliding trigger by the dual trigger bars. The safety is of the cross-bolt, push-button type and located above the pistol grip. There's no separate fire mode selector on the AUG rifles. Instead, the trigger itself is used to control the mode of fire. Pulling it half the way back will produce single shots, while the full pull will produce automatic fire. The enlarged triggerguard encloses the whole hand and allows the gun to be fired in winter gloves or mittens. The standard sighting equipment of the Steyr AUG rifle is the 1.5X telescope sight, with aiming reticle made as a circle. This circle is so dimensioned so its visible inner diameter is equal to the visible height of the standing man at 300 meters range. The adjustment knobs on the sight are used only for zeroing. The sight housing, which is integral to the receiver on the AUG A1 models, also features an emergency backup iron sights at the top of the telescope sight housing. Some early production AUG rifles of A1 pattern were fitted with receivers that had an integral scope mounts. On the AUG A2 models, the standard scope mount can be quickly removed and replaced by the Picatinny-type mounting rail. The housing of the AUG rifles, integral with the pistol handle and triggerguard, is made from the high impact-resistant polymer, and is usually of green (military) or black (police) colour. The housing has two symmetrical ejection ports, one of which is always covered by the plastic cover. The rubber-coated buttplate is detachable and, when removed, opens the access to the rifle internals, including the hammer unit and the bolt group. The buttplate is held in position by the cross-pin, which also serves a s a rear sling swivel attachment point. The AUG is fed from the detachable box magazines, that hold 30 (standard rifle) or 42 (light machine gun) rounds. The magazines are made from semi-translucent, strong polymer. The magazine release button is located behind the magazine port and is completely ambidextrous (some said that it is equally NOT comfortable for either hand use).
P99 PISTOL
Type: Double Action The P99 pistol was a rather radical step forward for the Walther company, made under new management. The development of a new pistol started in 1994 and the first production pistols were shown to public in 1997. The earliest pistols were made in 9mm, and a .40 S&W version appeared in 1999. By 2004, the Carl Walther company presented the second generation of the P99 pistols. These new guns had even better ergonomics, and new model designations – the old P99 was renamed (and slightly redesigned) to P99AS (Anti-Stress), the double-action only P990 turned into the P99DAO, and only the P99QA (Quick Action) retained its name. The second generation also included the P99 Compact pistols, apparently made with input from American company Smith & Wesson, as the basically similar SW99 Compact pistol appeared on the US market a little earlier. Smith & Wesson makes a close copy of the P99 as the SW99, using Walther-made polymer frames and its own slides and barrels of slightly different shape. S&W also makes a .45-caliber version of this pistol. 9mm P99 pistols also are manufactured under Walther’s license in Poland, and are standard police sidearms there.
How to field-strip (disassemble) Walther P99: 1) remove the magazine by pressing the magazine release button; 2) check that the chamber is empty; 3) on P99, P99AS and P99QA, press the decocking button; 4) press down and hold the disassembly sliders, located at either side of the frame, above the trigger; 5) push the slide forward and out of the frame; 6) remove the return spring assembly from below the barrel; 7) remove the barrel from the slide. Reassemble in reverse order.
THC Gun Of The Month- Octoberak-47 Assault Rifle
The AK-47 (short for Russian: Автомат Калашникова образца 1947 года, Avtomat Kalashnikova 1947) is an assault rifle used in most Eastern bloc countries during the Cold War. Adopted and standardized in 1947, it was designed by Mikhail Kalashnikov and originally produced by Russian manufacturer Izhevsk Mechanical Works.[3] Compared with most auto-loading rifles of World War II, the AK-47 is compact, of comparative range, moderate power, and capable of selective fire. It was one of the first true assault rifles and, due to its durability and ease of use, remains the most widely used assault rifle. More AK-type rifles have been produced than any other assault rifle type. Ballistics The standard AK-47 or AKM fires a 7.62 ﾗ 39 mm round with a muzzle velocity of 710 metres per second (2,329 ft/s). Muzzle energy is 2,010 joules (1,467 ftｷlbf). Cartridge case length is 38.6 millimetres (1.5 in), weight is 18.21 grams (281.0 gr). Projectile weight is normally 8 grams (123 gr). The AK-47 and AKM, with the 7.62 ﾗ 39 mm cartridge, have a maximum effective range of around 300-400 meters.
THC Gun Of The Month- SeptemberM4A1 Assault RifleThe M4A1 carbine is a variant of the basic M4 carbine intended for special operations use. The M4A1 can be found in use by many U.S. military units, including the Delta Force, U.S. Navy SEALs, U.S. Army Rangers, and the U.S. Marine Corps' Radio Reconnaissance Platoons and Force Reconnaissance companies. The M4A1 Carbine is specially favored by counter-terrorist and special operations units for close quarters combat because of the carbine's compactness and firepower. These features are also very useful in urban warfare. Although the M4 does not have as great an effective range as the longer M16, many military analysts consider engagement with a non-specialized small arm above a range of 300 meters to be unnecessary. It is effective at ranges of 150 meters or less. It has a maximum effective range of about 400 meters.
Caliber - 5.56mm NATO (.223 Rem) |
In general, the AUG is known for good ergonomics, decent accuracy and a good reliability.
Barrel replacement procedure, as noted above, takes only few seconds (assuming that the shooter has the spare barrel handy). To remove the barrel, one must take off the magazine, and clear the rifle by operating the cocking handle. Then, grasp the barrel by the front grip, push the barrel retaining button at the gas block, and rotate the barrel and pull it out of the rifle. To install a new barrel, simply push the barrel down into the front of the receiver all the way and then rotate it until it locks. The rifle now is ready to be loaded and fired.
The Walther P99 is short-recoil operated, locked-breech pistol. It uses a modified Browning locking system, with the barrel engaging the slide with a single large lug entering the ejection window. The frame is made from polymer and has interchangeable grip backstraps. Three backstraps of different shape are included with each pistol, so users can adjust the grip to their own preferences. The trigger is striker-fired, with an automated firing pin block safety, and varies with the model. The standard P99 is double / single action with a decocking button. Earlier P990s and current production P99DAOs are double action only, and the P99DAO also features a slightly different automated safety built into the trigger. The third variation of the P99 family is the P99QA, which features a partially pre-cocked trigger for a constant trigger pull from the first to the last shot. One feature, unique to the P99 series pistol triggers, is that despite being striker-fired, these pistols do not require the user to press the trigger during disassembly to disconnect the sear from the firing pin. This is done by using the decocking button, built into the top of the slide. This button is relatively large on the standard P99, as it is routinely used to decock the striker, and much smaller on the P99QA, as it is used only during disassembly to disconnect the firing pin from the sear. The P99DAO does not have such button, as its firing pin is always disconnected from the sear and at rest, except for the time the trigger is being pressed. The most recent Anti-Stress feature is, in fact, a modification to the trigger system which makes the trigger pull for the first shot in Single Action mode much longer than for subsequent shots. The Anti-Stress feature is activated each time the pistol is reloaded. Another safety feature is a striker cocking indicator, made in the form of a small pin, which protrudes from the back of the slide when the striker is cocked. First generation pistols had a slide release only at the left side of the frame, second generation guns may have optional ambidextrous slide stop release levers which, combined with ambidextrous magazine release levers built into the base of the trigger-guard, make these pistols truly left-hand friendly. All variations of the P99 use adjustable rear sights with white inserts. Magazines are of double-stack design.
