This video provides an in-depth review of the Colt I AR, a rifle submission for the US Marine Corps' Infantry Automatic Rifle (IAR) program. The presenter highlights its robust monolithic upper receiver with integrated aluminum heat sinks for superior heat mitigation, a key requirement for the contract. The review also details the performance of the Exigent Defense Fire Team 556 suppressor, noting its quiet operation and durability. While acknowledging the HK M27 IAR won the contract, the reviewer argues the Colt I AR was a superior design for sustained automatic fire, particularly in its short-barreled configuration.
