What do you get when you cross a car wash spray nozzle with a Thompson submachine gun? No, it's not a joke. It's a new and rather unconventional .45-caliber (.45 ACP) subgun that attenuates/mitigates felt recoil and muzzle rise/climb--thus increasing controllability--on full-auto by putting the bore axis at or slightly below the centerline of the shooter's fist and forearm and combining that ergonomic aspect with a mechanical recoil attenuation/mitigation system. It's called the KRISS Super V Sub-machine gun, and it's brought to you by the good folks at Transformational Defense Industries (TDI), headquartered in Washington, D.C. That's more than a little ironic. Think about it--a select-fire (full-auto capable) small arm being developed in D.C., one of the most anti-legal-firearms-ownership/anti-Second Amendment cities in the country. Most likely, TDI's manufacturing facility is located outside the District (in an actual state, somewhere), and it would seem logical that their testing facility would be located somewhere in Virginia. We'll look into it.
TDI claims that in addition to reducing felt recoil and muzzle rise on full-auto, the KRISS's unique design...
reduces weapon weight by as much as 50%. The total number of parts (including moving parts) is supposed to also be lower, but DefRev doesn't have a parts count, yet. According to the company, the KRISS Super V subgun can be adapted to other calibers. We assume this means that 9mm (9x19mm) and .40 S&W versions are possible. The TDI website states that the KRISS prototype has already been "extensively analyzed and tested by the US Army Picatinny Arsenal" (NJ), and that the the KRISS weapons platform "has proven itself to be a major step forward that can equip the war fighters of today with the ability to deliver a large quantity of high impact rounds with the accuracy that can only come from a low-recoil, light-weight weapon."
DefenseReview will try to acquire the results of those tests, ASAP. In the meantime, we highly recommend that our readers take a look at the KRISS Super V Sub-machine gun video clip (link below). From viewing the video clip, it's DefRev's opinion that TDI needs to do a just a few things with regard to further developing the KRISS:
1) Develop a 30-round magazine, or make the KRISS compatible with Thompson 30-round box mags.
2) Redesign and elongate the magwell so it can be used as a vertical foregrip, or design an actual vertical foregrip (fixed or folding) for the weapon. If a folding vertical foregrip is designed, it must be sturdy/robust. If a separate vertical foregrip is added, the barrel will most likely have to be lengthened slightly. Without a vertical foregrip, the firing method employed by the test shooters in the TDI video clip looks just a wee-bit dangerous for the shooter, as the support hand must be placed awfully close to the muzzle during full-auto fire. It just doesn't look safe to us. A robust vertical foregrip would provide for a much more secure (and thus safer) hold. It would also allow the KRISS to be used as a less-lethal blunt impact weapon for CQB/CQC (Close Quarters Battel/Close Quarters Combat), where lethal force isn't necessarily required.
3) Reduce the weapon's cyclic rate/rate-of-fire (ROF) a bit.

The triumphant advance of the smallest GLOCK pistol, specially developed for concealed carry and previously a domain of 5-round snub nose revolvers, started with the presentation of the GLOCK 26 in August 1994. The GLOCK 26 offers more than an alternative in this field. The magazine capacity of 10 rounds as standard and the highly accurate firing characteristics explain the worldwide distribution among security personnel and secret services.

HECKLER & KOCH G3
Type Battle rifle
Place of origin West Germany
Designer Mauser, CETME, Heckler & Koch
Weight 4.1 kg - 5.54 kg
Length 1,025 mm
Barrel length 450 mm
Cartridge 7.62×51mm NATO
Action Roller-delayed blowback
Rate of fire 500–600 rounds/min
Muzzle velocity 800 m/s
Effective range 500 metres (550 yd), 100–400 m sight adjustments
The G3 was and in some cases continues to be produced under license in: France (MAS), Greece (Hellenic Arms Industry), Iran (Defense Industries Organization), Luxembourg (Luxemburg Defense Technology), Mexico, Myanmar, Norway (Kongsberg Våpenfabrikk), Pakistan (Pakistan Ordnance Factories), Portugal (FBP), Saudi Arabia, Sweden (FFV), Thailand, Turkey (MKEK) and the United Kingdom (Royal Ordnance).
The G3A3 (A4) is a selective-fire automatic weapon that employs a roller-delayed blowback operating system. The two-piece bolt assembly consists of a breech (bolt head) and bolt carrier. The bolt is held in battery by two sliding cylindrical rollers that engage locking recesses in the barrel extension (popularly called a "trunnion"; BATF calls this a "mounting block"). The breech is opened when both rollers are compressed inward against camming surfaces driven by the rearward pressure of the expanding gases upon the bolt head. As the rollers move inward, recoil energy is transferred to the locking piece and bolt carrier which begin to withdraw while the bolt head slowly moves rearward in relation to the bolt carrier. As the bolt carrier clears the rollers, pressure in the bore drops to a safe level, the bolt head is caught by the bolt carrier and moves to the rear as one unit, continuing the operating cycle. The bolt also features an anti-bounce mechanism that prevents the bolt from bouncing off the barrel's breech surface. The spring-powered claw extractor is also contained inside the bolt while the lever ejector is located inside the trigger housing (actuated by the recoiling bolt).
The rifle is hammer fired and has a trigger mechanism with a 3-position fire selector switch that is also the manual safety toggle that secures the weapon from accidentally discharging (fire selector in the “E” or “1” position – single fire mode ("Einzelfeuer"), “F” or “20” – automatic fire ("Feuerstoß"), “S” or “0” – weapon is safe ("Sicher"), trigger disabled mechanically). The weapon can be fitted with an optional 4-position safety/fire selector group illustrated with pictograms with an ambidextrous selector lever. The additional, fourth selector setting enables a 3-round burst mode of fire.
The firearm was equipped with iron sights that consist of a rotary rear drum and hooded front post. The rear sight, mechanically adjustable for both windage and elevation, has an open notch used to fire up to 100 m and three apertures used for: 200, 300 and 400 m. The receiver housing has recesses that work with HK clamp adapters used to mount day or night optics.
The rifled barrel (contains 4 right-hand grooves with a 305 mm twist rate) terminates with a slotted flash suppressor which can also be used to attach a bayonet or serve as an adapter for launching rifle grenades. From the G3A3 the barrel had polygonal rifling. The barrel chamber is fluted, which assists in the initial extraction of a spent cartridge casing (since the breech is opened under very high barrel pressure).
The G3A3 (A4) uses either steel (260 g) or aluminium (140 g) double-stacked straight box magazines, or a 50 round drum magazine. Original H&K drums are rare and command high prices, a reproduction is available at much less cost from Allied Armament. H&K developed a prototype plastic disposable magazine in the early 1960s, but it was not adopted as aluminum magazines were just as light and proved more durable, as well as easier to produce.
Standard accessories supplied with the rifle include: a detachable bipod (not included with rifles that have a perforated plastic handguard), sling, cleaning kit and a speed-loading device. Several types of bayonet are available for the G3, but with few exceptions they require an adapter to be inserted into the end of the cocking tube. The most common type features a 6¾ inch spear-point blade nearly identical with the M7 bayonet, but with a different grip because of its mounting above the barrel. The weapon can also mount a 40 mm HK79 under-barrel grenade launcher, blank firing adapter a straight blowback bolt (called a “PT” bolt, lacks rollers) used for firing 7.62×51mm ammunition with plastic bullets, a conversion kit used for training with .22 LR ammunition and a sound suppressor (that uses standard ammunition).
The G3 is a modular weapon system. Its butt-stock, fore-stock and pistol-grip/fire-control assembly may be changed at will in a variety of configurations (listed below). For example: by simply removing push pins the fixed butt-stock can be removed and replaced with a telescoping butt-stock.

BARRETT MODEL 99
Rugged. Reliable. Uncomplicated. The Model 99 is designed for one thing only: to get the job done. With its brilliantly simple design, hard-core construction and surprisingly few moving parts, it offers match-winning accuracy time and time again. At the heart of this robust and accurate bolt action rifle is a one-piece 7000 series aluminum alloy extrusion. A heat-treated steel M1913 optics rail is attached to the top of the extrusion by closely spaced high-strength bolts. The match-toleranced barrel is pressed and locked into the receiver, creating a rock-solid unitized structure on which to mount a riflescope. The Model 99 barrel is made in a heavier contour to ensure repeatable accuracy. The chamber area is encased by the thick-walled aluminum extrusion of the receiver, resulting in unparalleled safety for the shooter.
The bolt is machined from a single piece of shock-resistant tool steel. The action’s strength is exemplified by the 15 bolt lugs that lock into the machined barrel extension. The bolt’s few moving parts, an extractor, ejector and firing pin assembly, make it reliable and easy to maintain.
The Model 99 is easily disassembled without tools by removing three quick-release assembly pins. These pins attach the trigger housing and bolt guide to the receiver assembly. The match-quality trigger design is exclusive to Barrett and virtually maintenance-free. The bipod can easily be detached for benchrest shooting.
