The US Army recently published a market survey for the Precision Grenadier System, with a few more details on the overall system:

- System: weapon + FCS + ammo
-Max effective range of 500 m (desired)
-OaL ≤ 863 mm
-Weight ≤ 6.6kg
-Self-loading (desired)
-Tof: ≤ 3 s to 500 m

The PGS will be a man portable integrated weapon system that enables precision engagements to destroy personnel targets in defilade and in the open with increased lethality and precision compared to the legacy M203/M320 grenade launchers. The PGS will provide overmatch to comparable threat grenade launchers in near peer formations in future operating environments (jungle, urban, woodland, subterranean, desert, day/night/obscured). The PGS is envisioned to consist of a weapon, a fire control, and a suite of ammunition which enables the user to engage targets in defilade/cover, hovering UAS targets, conduct door breaching, engage close combat targets, and light armored targets.
Based on past results, the Government has determined that specific technologies and components are available to accomplish this mission and is looking for a fully integrated, armament solution. Vendors are encouraged to team as necessary in response to this market survey / sources sought notice. The Government anticipates a single vendor to be the lead system integrator.
The following integrated system attributes are outlined in order of importance. The Government is interested in receiving information on the attributes that can be achieved:
- System Survivability:  The system and its ammunition should be capable of functioning in cold, ambient, and hot conditions at all humidity conditions and be survivable and operational after exposure to chemical, biological, radiological, nuclear exposure (CBRNE) to include effects of electromagnetic pulse and cyber-attacks.
- System Effectiveness:  Ability to achieve a high probability of incapacitation given a shot from the minimum engagement distance to 500 meters (desired) against unprotected personnel targets in defilade/cover and stationary exposed targets.
- Engagement Times:  Time to engage target is desired to be ≤ 5 seconds from decision to engage to trigger pull for a target out to 500 meters.  After trigger pull, time of flight is desired to be no greater than 3 seconds to 500 meters.
- Length:  Overall system length is desired to be less than 34 inches.
- System Weight:  System weight is desired to be less than 14.5lbs.
- Target Acquisition:  Ability to acquire targets with a high Probability of Recognition given a detection out to a range of 500 meters in clear air during day and nighttime conditions and a high Probability of Recognition given a detection out to a range of at least 300 meters in obscurants is desired.
- Powerless/Degraded Operation:  The system provides the ability to continue the fight and engage targets even when the fire control has no power or becomes damaged and inoperable is desired.

Family of Ammunition:
a.    Counter Defilade Round:  Round to precisely and quickly defeat personnel targets in defilade positions.
b.    Training Round:  Non-pyrotechnic round ballistically similar to the counter defilade round to train the PGS capability.
c.    Expanded Capabilities: Ability to expand capabilities is desired with different types of ammo such as:
i.    Armor-Piercing Round
ii.    Close Quarters Battle Round
iii.    Counter Unmanned Aerial System (UAS) Round

- Variable Magnification:  System capable of having variable magnifications to enable accurate engagements within the range of the systems capability is desired.
- Ranging/Far Target Location:  Capable of accurate range determination to a man-sized target out to 800 meters and vehicle or troops in the open (squad sized targets) out to 1,000 meters in less than one second is desired.
- Digital Overlay:  System capable of providing alpha-numeric display and a dynamic reticle within the fire control field of view out to a range of 1000 meters is desired.  System can calculate a dynamic reticle for refined targeting including (but not limited to) range to target, atmospheric conditions, weapon orientation, and ballistics of the weapon/ammunition selected is desired. The computation time for the dynamic reticle to be displayed is desired to be no more than 1 second.
- Firing Mode:  System capable of semi-automatic firing is desired.
- Resolution:  System provides sufficient angular resolution to distinguish between hostile and non-hostile targets during daytime, clear air conditions from 0-600 meters and accurately determine threat characteristics (e.g. a threat light armored vehicle or armed squad size element in the open) during daytime, clear air conditions out to 1,000 meters.
- Ambidextrous:  System capable of ambidextrous configuration without degradation of performance or safety is desired.

Q18: Will the PGS replace only the M320 or both the M4/M4A1 and M320 carried by the Soldier?
A: Fielding considerations are not finalized; however, the PGS is intended to replace the M320 or the M4A1/M320 in CCF organizations depending on unit composition.

Q22: Has the basic carry load of the ammunition been established?
A: The basic load is envisioned as 45 rounds, subject to METT-TC considerations, and risk that commanders weigh while considering threat, terrain and other considerations. For example, certain missions in certain places may require a higher number of C-UAS rounds to be carried, as an example, while other mission may require more breaching rounds. These decisions are made by commanders. 45 rounds is a planning guide. Doctrinally there is no such thing as a basic load.
