Una cuestión adicional: una vaina abotellada dificulta la expulsión adelantada respecto a una telescópica, ¿no?

Ese cartucho es básicamente imposible que se adopte. Lo que está apostando MARS es porque se adopte su sistema patentado de cierre por retroceso largo y buffer.

Puede ser brutal como dije, pero por volver a 20 cartuchos por cargador no hago el cambio, salvo que el proyectil tenga guía terminal.

US Army Selects Three Companies To Vie For Next Generation Squad Weapons to Replace M249 and M4
por SSD vía Soldier Systems Daily
Last night, the Army announced the three companies which will proceed to Phase 2 of the Next Generation Squad Weapons Program. Solicited this Prototype Project Opportunity Notice (PPON) as a Other Transaction Agreement under Section 804 Authority.
The PPON called for each vendor to develop two weapon variants under the NGSW program and 6.8 millimeter ammunition common to both weapons. This is NOT the 6.8 SPC cartridge evaluated by USSOCOM in the early 00s, but rather more akin to 270 WSM.
The three companies selected are:
W15QKN-19-9-1024 – General Dynamics-OTS Inc. – Williston, VT
W15QKN-19-9-1025 – AAI Corporation Textron Systems – Hunt Valley, MD
W15QKN-19-9-1022 – Sig Sauer Inc. – Newington, NH
Although the Army has tried over the years to find a replacement for the M-16 family of weapons, which the M4A1 Carbine is the latest iteration of, none have been successful. Each and every time, the Army has found that the candidate weapons did not result in a great enough improvement in lethality to replace the status quo.
Specifically, the Army is seeking a Next Generation Squad Weapon-Rifle (NGSW-R) and Next Generation Squad Weapon-Automatic Rifle (NGSW-AR). The NGSW-R is the planned replacement for the M4/M4A1 Carbine and the NGSW-AR is the planned replacement for the M249 Squad Automatic Weapon (SAW) in the Automatic Rifleman Role in the Close Combat Force.
According to the solicitation, the duration for each prototype OTA is estimated to be up to eight years. The first 27 months will be for prototyping the NGSW-R, NGSW-AR, and ammunition. Following this prototyping effort, there may be additional iterative prototyping efforts for the NGSW-R, NGSW-AR, and ammunition. These iterative prototyping efforts will each have separate durations and will occur within the eight year duration.
Furthermore, in accordance with 10 U.S.C. 2371b(f), and upon a determination that the prototype project (or any subsequent iterative prototyping efforts) was successfully completed under the competitively awarded OTA(s), a follow-on production contract(s) or OTA(s) may be awarded without the use of competitive procedures.
Because of the duration of the OTA, and that prototype OTA will undergo two prototype test events including Soldier Touch Points, they are asking for a lot more weapons and ammunition than in the current NGSAR PON. Deliverables for each prototype OTA include 53 NGSW-R weapons, 43 NGSW-AR weapons, 845,000 rounds of ammunition, spare parts, test barrels, tools/gauges/accessories, engineering support, and iterative prototyping efforts as defined in the Statement of Work.
The follow-on production award(s) is planned to be an Indefinite Delivery / Indefinite Quantity Federal Acquisition Regulation (FAR) based contract with Firm Fixed Price Delivery Orders up to ten years or a fixed amount OTA up to ten years. The production award(s) may include 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 value of this follow-on production award(s) is estimated to be $10M in the first year and estimated $150M per year at the higher production rates.
GD comes in partnered with True Velocity ammunition and their polymer case design.

Additionally, we hear that GD submitted a bullpup carbine, which several sources have claimed is what the Marine Corps hopes to get from NGSW. Considering the 6.8mm requirement, rumors that they are using the Desert Tech MDR seem like a good bet.

AAI Textron is seen by many as the government solution as their weapon and Case Telescoping technology has been funded for years under the Lightweight Small Arms Technology program.

It is the most radical departure of the three from currently fielded weapons. This is a video of their technology demonstrator shown at a recent industry meeting.
During SOFIC, SIG SAUER exhibited their Next Gen solution. They are producing the weapons and annunciation themselves.

Despite the ammo case’s three component construction this looks to be the lowest risk design.

This program is moving along very quickly considering vendors just delivered prototypes to the government at the end of May.
