LMG-A Objective Statement 9Oct24 FINAL.docx

UNCLASSIFIED

1. Scope This specification establishes the desired performance characteristics of the USSOCOM Lightweight Machine Gun – Assault (LMG-A). The LMG-A is intended to replace the legacy MK48 for a lightweight assault machine gun. The LMG-A will extend the range of suppressive fire capability out to 1500m. The LMG-A shall be accurate to 6.0 MOA (T) / 3.0 MOA (O) at 100 yards firing 7.62mm NATO ammunition and USSOCOM TDP 6.5CM ammunition. USSOCOM is also interested the capability of the LMG-A to adopt other calibers such as 6.8x51mm high pressure ammunition (U.S. Army TDP) and the .264 Lightweight Intermediate Caliber Cartridge (.264 LICC) via caliber conversion kits.

2. Description

2.1. Major Components

a) The LMG-A shall be a lightweight belt fed, multi-caliber system which will include a primary barrel, spare barrel, with required bolts, barrels, and operating groups for each caliber, buttstock, receiver, sound/signature suppressor, operator manual, cleaning kit, operator tool kit, maintainer tool kit, spare parts kit, training munition kit, bipod, backup iron sights, sling, and a Transportation Security Administration (TSA) approved locking hard carrying case capable of storing a fully accessorized weapon.

3. Operation and Performance characteristics

a) The LMG-A shall be capable of firing in fully automatic and semi-automatic firing modes.

b) The LMG-A shall have an ambidextrous safety selector that prevents the weapon from being fired when the trigger is depressed and the weapon is on SAFE (T), capable of charging the weapon when the weapon is on SAFE (O).

c) The LMG-A shall be capable of firing 7.62x51mm NATO family of belted ammunition to include training munitions, and USSOCOM TDP 6.5 Creedmoor belted ammunition via left-hand feed.

d) The LMG-A shall have AMR not to exceed 6.0 MOA (T), 3.0 MOA (O) at 100 meters (109 yards) when firing 7.62 NATO ammunition.

e) The LMG-A shall be equipped with quick-change barrels in assault and standard configurations.

f) The LMG-A shall be capable of being suppressed, while reducing the signature of the weapon in flash, ground disturbance, sound, and gas blowback. The suppressor shall not modify the rate of fire by more than 10% (T) or 2% (O).

g) The LMG-A suppressor shall be of a quick-detach, lockable design, and minimize Point of Aim/Point of Impact shift when mounted or dismounted.

h) The LMG-A shall have a two-position, non-reciprocating charging handle that is operable and moveable to both the left and right-hand side of the weapon.

i) The LMG-A shall have a user-adjustable bipod that is rapidly deployable/stowable and provides tension and lockup upon loading.

j) The LMG-A buttstock shall have an adjustable for length (T), collapsable (T) side folding (O), and adjustable cheek riser (O) that does not interfere with the function of the weapon.

k) The LMG-A shall have a maximum overall length with bipod attached, buttstock, and barrel (with suppressor) of 49.0 inches (T) less than or equal to 44.0 inches (O). Sights and other accessories will not be included in the weight requirement.

l) The LMG-A shall weigh no more than 17.0lbs (T), 12.75lbs (O).

m) The LMG-A shall have Mil-STD-1913 rails, with numbered slots at the 12 o’clock position with a minimum of 8.50 inches aft of the feed tray cover for optical sights.

n) LMG-A shall have M-LOK attachment points at the 3, 6, and 9 o’clock positions on the forward handguard to support the attachment of accessories and enablers.

o) The LMG-A shall have a rate of fire between 500-750 rounds per minute (T=O).

p) The LMG-A shall minimize felt recoil across all firing modes.

q) The LMG-A shall have a single mounting point for DoD-common weapons mounts.

r) the LMG-A shall have a mounting point for common ammunition carrying boxes or soft pouches.

For additional information on the desired capabilities, parameters, and attributes for the LMG-A, please reference the draft Performance Specification attached to this Request for Information (RFI). Interested respondents should include a white paper and quad-chart in their proposal detailing their approach to meet this requirement.

USSOCOM will host a two-day industry event at SOFWERX in Tampa, Fl., on November 19th & 20th. For interested vendors to meet with the program office to discuss submissions and refine the requirement. Vendors that are planning on attending are requested to bring a physical weapon or prototype mockup along with a white paper and quad chart for individual discussions. Live ammunition is not permitted, and all weapons will be verified safe and clear upon entrance.
