All firearms and magazines used for function testing shall undergo a Technical Inspection (TI) and be cleaned and lubricated before testing is conducted. The ability of the ammunition sample to function in firearms will be evaluated by firing 750 rounds in 3 firearms per make/model (250 rounds per individual firearm). Function testing will be conducted in the following make/models: Colt M4 carbine (11.5” 1:7” twist 5.56x45mm NATO barrel, 0.070” gas port, H2 buffer, with and without AAC M4-2000 suppressor), and the ICE Mk12 rifle (18” 1-7.7” twist .223 Remington Wylde barrel, rifle length gas tube, 0.0995” gas port, Vltor A5 receiver extension system, with and without Ops Inc M4/Allen Engineering AEM5 suppressor). After contract award, lot function testing may be conducted with any new 5.56x45mm NATO firearm adopted or authorized by ICE. Acceptance criteria are delineated in Section 3.13 and Table II for each type of ammunition malfunction. Any firearm and magazine used for function testing that experienced a disqualifying malfunction or misfire shall undergo a post evaluation Technical Inspection.

4.13 Environmental Conditioning.

4.13.1 High Temperature. Two loaded 30-round magazines will be placed in an environmental conditioning chamber set at 135 ±5°F for 8 hours. Each magazine will be individually removed from the environmental conditioning chamber and fired within 1 minute in an ICE duty firearm.

All rounds in each magazine shall be fired within 20 seconds after initiating firing. Ammunition expended in the function test will be visually examined for cracked or perforated cases.

4.13.2 Low Temperature. Two loaded 30-round magazines will be placed in an environmental conditioning chamber set at –35 ±5°F for 8 hours. Each magazine will be individually removed from the environmental conditioning chamber and fired within 1 minute in an ICE duty firearm.

All rounds in each magazine shall be fired within 20 seconds after initiating firing. Ammunition expended in the function test will be visually examined for cracked or perforated cases.

4.13.3 Saltwater Immersion. Sixty (60) rounds of ammunition will be submerged in a 5% by weight saltwater solution for 1 minute, removed from the saltwater solution, and then placed in an environmental conditioning chamber set at 70 ±5°F and 70 ±5% relative humidity for 24 hours.

The rounds will then be loaded into 30-round magazines and fired in an ICE duty firearm. This evaluation will be conducted within 20 minutes after environmental conditioning. All rounds in each magazine shall be fired within 20 seconds after initiating firing. Ammunition expended in the function test will be visually examined for cracked or perforated cases.

4.14 Visible Muzzle Plume. A high-speed camera and/or thermal imaging device will be used to detect any visible muzzle plume emitted from the muzzle while firing. Five rounds will be fired in a darkened range from a Colt M4 carbine (11.5” barrel) with standard A2 flash hider.

4.15 Luminous Ejecta. A high-speed camera and/or thermal imaging device will be used to detect any luminous ejecta emitted from the breech during cartridge extraction and ejection. Five rounds will be fired from a Colt M4 carbine (11.5” barrel).
