En Francia ya digeron hace un tiempo que el recambio no iba a ser Bullpup, y en gran Bretaña, que no lo han cambiado por vergüenza ahora que se han gastado un pastizal en hacerlo útil, ya han dicho que seguramente cuando llegue el repuesto no será Bullpup.

Y ojo, que estos últimos dicen que son más fiables (cuando están bien) que el M4 por ejemplo, pero muy poco robustos que es distinto.

El cálculo es malo, y me explico:
un FUSA debería ser un consumible. De acuerdo que debería servir para al menos 10.000 disparos, pero... ¿Cuánto cuesta un FUSA? y ¿Cuánto cuestan 10.000 cartuchos de SS109? Pongamos en el mejor de los casos, 0,30€. Haced las cuentas.
No debería tener importancia que elementos básicos del rifle (cierre, cañón, furnitura) vayan sucumbiendo. De hecho, en la vida útil de un diseño (que no debería superar una generación), se debería asumir un lote inicial y luego una adquisición en cascada y sustitución de piezas o de productos enteros a lo largo de ese período. Por una parte, sale quizás más caro que una gran compra unitaria. Por otra, aseguras el trabajo continuado a una fábrica, lo que en sí mismo tiene valor y debería reflejarse en el precio.
la corneta tenía el problema de su cierre Kiraly. Aparentemente magnífico, en realidad no. Por mucho que se intente, un cierre de retroceso directo y retrasado se somete a mucho más estrés que un cierre rotativo y con pistón, y eso acaba afectando a distintos elementos del arma. El F88 sigue ahí, es la base de una industria australiana que lo va haciendo evolucionar poco a poco y un producto realmente magnífico.
No acabo de ver la dicotomía fragilidad/fiabilidad. Si un arma es frágil, no puede ser fiable porque no va a cascar cuando nos convenga a nosotros. Y, si lo piensas, la diferencia entre un bullpup y un convencional es la posición del pistolete y del mecanismo de disparo. Nada más. El resto es exactamente igual que un diseño convencional. Por ejemplo, el SA-80 es esencialmente un diseño AR-18, pistón de retroceso corto y cierre rotativo. Esencialmente igual que el G36 y otros tantos diseños, aunque ejecutado con el culo... por parte de ingenieros no especializados, aunque suene de broma.
Mecánicamente, un FUSA bullpup no tiene por qué ser más frágil que un FUSA convencional.
The backbone of MSBS system is an inverted U-shaped receiver, made from aluminum alloy. This receiver, along with bolt group, return spring, barrel and gas system are common for both current versions of MSBS rifles.
MSBS is operated using short stroke gas piston, located above the barrel, and its gas system has manual gas regulator. Breech lock is achieved by a conventional rotary bolt with seven radial lugs that lock into the barrel extension. Ejection windows are made on both sides of the receiver, and weapon can be set up to eject to either side; this requires partial disassembly of the gun and installation of the ejection port cover on the side opposite the “active” ejection window. Non-reciprocating charging handles are located on both sides of the receiver.

Military.com 8 Oct 2018 By Matthew Cox
The U.S. Army's chief of staff said Monday that its 6.8mm, next-generation weapons, slated to replace the M249 squad automatic weapon and the M4A1 carbine, will be able to penetrate any body armor on the battlefield.
"It will fire at speeds that far exceed the velocity of bullets today, and it will penetrate any existing or known ... body armor that's out there," Gen. Mark Milley told Military.com at the 2018 Association of the United States Army's Annual Meeting and Exposition. "What I have seen so far from the engineers and the folks that put these things together, this is entirely technologically possible. ... It's a very good weapon."
Milley's comments come on the heels of an Oct. 4 draft solicitation announcing the Army's plans to "award up to three prototype Other Transaction Agreements ... with each offeror developing two weapon variants and a common cartridge for both weapons, utilizing government-provided 6.8 millimeter projectiles," according to the solicitation posted on the federal contracting website FedBizzOpps."The weapons include the Next Generation Squad Weapon-Rifle (NGSW-R) and the Next Generation Squad Weapon-Automatic Rifle (NGSW-AR)."
The Army also intends to make follow-on production awards for "250,000 total weapons system(s) (NGSW-R, NGSW-AR, or both), 150,000,000 rounds of ammunition, spare parts, tools/gauges/accessories, and engineering support," the solicitation states.
The awards could be worth "$10 million the first year and $150 million per year at the higher production rates," it adds.
The solicitation comes about three months after the Army announced it had selected five gun makers to build prototypes of the next-generation squad automatic rifle.
The contracts were the result of a prototype opportunities notice the Army posted in March for the small-arms industry to submit ideas for the NGSW-AR, an effort to replace the M249 squad automatic rifle, made by FN America.
Milley would not comment on the recent prototype contracts, but said that there were "several prototypes that were advanced forward."
He added that the Army will likely not "speak too much about its technical capabilities because our adversaries watch these things very closely."
"It's a very sophisticated weapon, a very capable weapon. It's got an integrated sight system to it, and it also integrates into the soldier's gear and other equipment that we are fielding," Milley said. "And not surprisingly with a weapon like that, it's probably pretty expensive. We expect it to be expensive so we are probably not going to field the entire Army with this weapon."
He explained the service will likely field these cutting-edge weapons to infantry and other close-combat forces.
"The bottom line is we are committed to a new rifle and a new squad automatic weapon," Milley said. "We hope to be able to shoot it on ranges down at Fort Benning, [Georgia], hopefully ... maybe sometime next year late summer."

This new rifle optic basically guarantees ‘one shot, one kill’
By: Kyle Rempfer 2 days ago
Israeli defense firm Smart Shooter showcased a new optical device for assault rifles that the company said virtually guarantees rounds on target.
SMASH 2000 Plus is a ruggedized optical device that can be placed on a wide range of legacy small arms, including the M4 Carbine.
The system works by tracking potential ground and aerial drone targets using a day or night mode with a traditional red dot sight picture. Once found, it works out a firing solution even as a soldier’s natural breathing and fatigue draws his aim off target. All a soldier has to do is hold the trigger down.
When the solution is calibrated, the round is let loose, hitting the target and nothing else, Smart Shooter officials told Army Times at the Association of the United States Army’s annual conference in Washington, D.C., this week.

“The human factor is the main reason soldiers and policemen miss the target ... because they are under stress and fatigued,” said Nir Kaveh, Smart Shooter’s marketing director.
“What we promise here is that almost every bullet will be on target, by controlling the exact moment when the bullet is released," Mazor added. “So if you’re not on target, you won’t be able to fire.”
In essence, the system adds digital precision to rifles and ammunition already fielded to troops.
While the system is designed for the rigors of close-quarters combat, it’s also able to quickly revert back to free-fire mode through the click of a button.
During one trial, Kaveh said the company took a group of Israeli soldiers and drastically increased the proportion of rounds on target.
Indeed, SMASH 2000 has been in use by the Israel Defense Forces since earlier this year, according to the company. However, Kaveh wasn’t allowed to specify which units and where the system was being fielded.
SMASH 2000 Plus is the latest variant of the SMASH system. The new variation is specifically designed to also lock, track and accurately hit fast and maneuverable tactical drones during the day and at night.
“Drones are increasingly used by insurgents to improve their situational awareness and even drop bombs on patrols," Michal Mor, CEO of Smart Shooter, said in a company release.

“Their [drones'] small size and speed make them hard for a normal shooter to tackle effectively, but SMASH makes it easy, denying enemy forces those advantages,” she added.
SMASH has been successfully tested by U.S. special operations forces and other military agencies, the company said.
The platform is also undergoing testing with the Australian Defence Force, as a combined effort with Thales Australia as part of the Australian Army’s F-90 assault rifle upgrade program.
Also of note, the SMASH system provides an optional video recording function of engagements for training or after-action debrief and analysis. Like all optics, it still needs to be “zero’d in" to the rifle on which it’s mounted.
The company also offers a SMASH 2000M with a 4x increase in magnification, as well as a SMASH 2000N with enhanced night capabilities
