Part 3 of 3--Q & A
>>Area suppression lethality module - what is the minimum life required for firing 40mm grenades? Will the requirement be to mount the M203 or the XM320? If it is for the XM320, will we be provided a sample (or drawings of the interface) to determine compliance for attachment?
There shall be no degradation in reliability or damage to the host weapon system. The requirement is to provide attachment points that serve as recoil bearing surfaces to withstand the recoil forces generated by the ASLM. It is possible that the ASLM interface can be modified (if required) to mount on the OICW Increment I.
>>Acoustic and blast suppressor compatibility - since no suppressor is required as part of the OICW submission, is it required to fit some specific suppressor or is some specific mount required?
Not being evaluated under the Bid Sample Tests.
>>Sling - please define "quick release type fasteners".
Fasteners that can be attached/removed quickly and without tools. For example, pushing a button to release a latch. No screws.
>>Collapsible/adjustable bipod - please define how much adjustment is required for the bipod. Please define what is meant by "minimum torque TBD ft-lbs in the direction opposite of the forward movement".
The Performance Specification para 3.6.15 has been updated to reflect the following requirement. The DM and LMG shall have a collapsible and adjustable bipod. The bipod, shall have a collapsed length from the centerline of the bore of no more than 10.75 inches. When extended, the length of the bipod shall be no less than 14.0 inches when measured from the centerline of the bore. When extended/open, the bipod shall be able to withstand a minimum impact energy of 88.40 lbf-ft at an angle of 55 degrees without collapsing or loss of functionality.
>>Accessory attachment points - please explain what is meant by "capable of alignment with respect to the barrel, accurately, and repeat ably". Fixed rails are designed to be parallel to the barrel. Are permanent/fixed rails considered to be integral and will they meet the objective?
The sentence "capable of alignment with respect to the barrel, accurately, and repeatably" refers to being able to remove and mount the sight or other FC accessory and maintain alignment with the barrel. Permanent/fixed rails may meet this requirement.
>>Resident accessories power - please explain if this requires one central power supply to be used for all resident accessories.
As a threshold, a common type power source means, for example, a battery that is available commercially and easily procured. The objective requirement is to operate from a single, central power supply.
>>Round counter - please explain if this can also be used to replace requirement 3.8.6 for inventory with an automated system. Also, please explain what is meant by "powered from the OICW common type power source". We are unaware of any round counter that can count, give date and time and differentiate between ball and blank rounds. Please provide information on what type of interface will be required. Please provide information that is TBD. Will this be based on battery life or equipment life? Can the round counter be integrated with the Fire Control?
This requirement is separate from 3.8.6. However, it is not exclusive, if the offeror can combine the two, that may be beneficial. Powered from the OICW common type power source means uses the same battery type. Interface with the rounds counter is up to the offeror to determine. There is no TBD on this requirement. While the round counter may be integrated into the FC, it must remain with the weapon if the FC is removed.
>>Workmanship - should the section "hammering to shape" be interpreted to not allow hammer-forged barrels or does it only apply to repair operations?
"Hammering to shape" refers only to repair operations during manufacturing of the weapons.
>>Can you please specify the Threshold and Objective goals for weapon unit weight? There are conflicting numbers in the specification.
The weights have been updated to reflect the weights as shown in sections L&M. The Carbine system should weigh no more than 9.19 lbs, which is equivalent to an M4 MWS with an M68, BUIS, PEQ-2A, visible red laser pointer, white light flashlight, and empty magazine. The SC system should weigh no more than 8.39 lbs which is equivalent to a modified M4 MWS with a ten (10) inch barrel, an M68, BUIS, PEQ-2A, visible red laser pointer, white light flashlight, and empty magazine. The DM system should weigh no more than 11.43 lbs which is equivalent to an M16A4 MWS with an ACOG, BUIS, PEQ-2A, Harris bipod, visible red laser pointer, white light flashlight, and empty magazine. The LMG system should weigh no more than 16 lbs without sling or ammunition.
>>The specification asks for a “family of stocks” for the rifle but provides no information about what capabilities and requirements are being met. Please provide specifics as to what this “family of stocks” should be able to accomplish and whether a universal stock capable of meeting all specs & requirements would be equally acceptable.
A family of stocks refer to interchangeable stocks that may be used on any variant. E.g. if the Carbine has a standard stock, and the DM has a DM specific stock, the soldier may interchange them as needed for the mission. Specific stocks are based on the offeror, and are not mandatory. As long as the requirements for each variant are met (size and weight), a universal stock is acceptable.
>>Section M.11.1.a states that it will be considered a weakness if a single weapon is capable of performing multiple roles within the OICW family. Can the Army please provide a justification for this rating? If a manufacturer can produce a single weapon that meets all of the performance requirements, e.g., for the Carbine and Special Compact rifles, why would the Army specifically choose to have multiple models with different logistic needs in inventory? Similarly, if a Carbine is capable of meeting the accuracy requirements of the Designated Marksman rifle, why would it be considered a negative that all of the delivered Carbines would be suitable for use as a DM weapon?
The RFP has been updated to reflect that a weapon system that is capable of serving dual roles and meet the requirements, will not be rated negatively.
