STATEMENT OF WORK

1. The weapon must be commercially available and in serial production. All weapons procured under this solicitation shall be of new manufacture. Rebuilt, overhauled, remanufactured, or “seconds” shall not be accepted.

2. After the selection process is complete, the awardee will be required to notify the Contracting Officer’s Technical Representative and the Contracting Officer at least sixty (60) days in advance of any changes in material, make up, or specifications of the weapon prior to shipping. The purchaser may require a sample with the changes incorporated for examination, evaluation and approval prior to shipping.

3. The weapon must be operable, without modification or alteration, by a right or left-handed user, firing with the right or left hand, depending on handedness.Is that a real word?

4. All metal parts of the weapon shall have a dark subdued, rust/corrosion resistant finish. The finish shall be unaffected by commercially available gun cleaning solvents, such as Simple Green, used in heated ultrasonic cleaning tanks.

5. All metal components and finishes shall be capable of withstanding cleaning using commercially available cleaning solutions, such as Simple Green all-purpose cleaner/degreaser, designed to be used in heated ultra sonic cleaners. Flaking, peeling, blotching, etc. of the finish is unacceptable.

6. The weapon shall be 5.56 x 45mm caliber (US Mil. Spec.) and function with assorted ammunition to include - M855, frangible and training ammunition. Chamber dimensions shall conform to current U.S. Military specifications for 5.56 x 45mm.

7. The weapon shall come equipped with a flash suppressor.

8. The weapon shall utilize a gas operated short stroke piston system.

9. The weapon shall be selective fire, i.e. semi-automatic and full automatic. A “burst limiter” in the full-automatic mode is not acceptable.

10. The fire control selector shall have three positions; safe, semi-automatic and automatic and shall rotate manually without binding from one position to another when the hammer is cocked. The selector shall remain in place in each position by a perceptible spring detent load until manually reset. Additionally,
a. With the hammer cocked, when the selector is placed in the “SAFE” position, it shall prevent the trigger from releasing the hammer so that the weapon is incapable of being fired.
b. When the selector is placed in the “SEMI AUTOMATIC” position, it shall permit the disconnect to engage the hammer, so that the weapon is capable of semi-automatic fire only (one shot with each pull of the trigger).
c. When the disconnect has engaged the hammer and the trigger is released, the disconnect shall release the hammer without the hammer falling.
d. When the selector is placed in the “AUTO” position, it shall permit the automatic sear to engage the hammer, so that the weapon is capable of automatic firing (continuous firing until the trigger is released or all cartridges are expended).

5. The fire control selector shall be ambidextrous and must be capable of being operated with the thumb of the shooting hand without removing the shooter’s hand from the rear pistol grip.
