On the 26 June the US Army posted a pre-solicitation notice stating that they are looking for an optic for mounted machine guns. The US Army Contracting Command notice calls for an optic which can be mounted on both the 7.62x51mm M240B, the .50 calibre M2/M2A1 Machine Guns and the 40mm Mk19 grenade launcher.

The pre-solicitation comes ahead of an anticipated Request for Proposals from Project Manager Soldier Weapons (PM SW). PM SW are looking for optics which will give faster target acquisition times and increased first burst hit probability for vehicle mounted automatic weapons.

Here are the key parts of the notice:

The Army Contracting Command – New Jersey (ACC-NJ), Picatinny Arsenal, NJ 07806-5000, on behalf of Project Manager Soldier Weapons (PM SW), anticipates issuing a RFP to for the procurement of the MMO on or about July 16, 2018. The Mounted Machine Gun Optic (MMO) is required to achieve faster target acquisition times and increased first burst Probability of hit (P(h)) for machine gunners firing from vehicle mounted platforms with the M240B, M2/M2A1, and Mk19 Machine Guns. The MMO procurement is planned as a Full & Open Competition (F&OC) acquisition seeking a system solution that will enable warfighters to scan with both eyes open, then rapidly slew the weapon on target, and engage with a higher confidence of getting the first burst on target. The MMO addresses the Joint Operations Concepts key characteristics through rapid, lethal, precision engagements in adverse conditions; provides endurance and resiliency through improved reliability growth; and supports agility and expeditionary needs through improved maneuverability. The applicable NAICS code is: 333314.

The acquisition approach is to issue a full and open competitive (F&OC) solicitation utilizing the tradeoff methodology to evaluate and select the best value system that meets the requirements of the Mounted Machine-gun Optic. As a result of the F&OC, up to three (3) Firm Fixed Price (FFP) Indefinite Delivery Indefinite Quantity (IDIQ) contract(s) with options per weapon platform will be awarded. Each contract will be issued a delivery order of thirty-five (35) units, which also satisfies the minimum ordering per awarded contract. This hardware will undergo developmental and user testing, generating data which will inform the exercising of full-rate production (FPR) options per weapon platform. Awards are anticipated to be made in 4th quarter of fiscal year 2018.

Up to 3 contracts could be awarded for 35 optics each these will be used in developmental testing and user testing ‘within a period of performance of 90 days from contract award’. Based on this testing production options for a potential IDIQ contract for a maximum quantity of 11,450 optics. An official RFP is expected to be posted in mid-July with awards anticipated to be made in 4th quarter of fiscal year 2018.

    The MK19 should have a different, Smart Optic with laser range finder to allow the use of 40x53mm airbursting grenades which have been developed by STK and Rheinmetal.

    Carlos Hathcock, the Vietnam sniper... in a book about him I did read, that he had installed an optic on a .50 cal and did even hit some Vietnamese with that over large distances. This was back then, when the long rifle enthusiasts among the GIs ordered their weapons back in the USA - and got them delivered to Vietnam.

    I wonder, if the Muricans read the books of their heros too. Hathcock btw was not demanding a sniper program, but a sharpshooter (in german - Heckenschütze) program. Well, now he was heard: the CSASS from H&K, the G28... only almost 50 years later...

    And the "mail order equipement" - I wonder, if this still works today. The ordinary american civilian makes a better equiped impression, then his counterpart in the armed forces.

    But at least have the Muricans an army, my country, Germany, not anymore... But who knows, what this is good for: Our next potential enemy would be Russia - and a conflict with them might not go ballistic, but nuclear...
