The Gear Locker takes a look at the EMG/CYMA CGS Lightning Series Colt 723, a gas blowback rifle designed as a replica of the carbine used by Delta Force during the late 1980s and early 1990s. He checks its historical accuracy, noting features like the N1-style stock, the C7-style upper receiver with a fixed carry handle, and period-correct Colt markings. While he points out minor issues with the laser-etched serial number and missing barrel markings, the external build is described as a faithful recreation for enthusiasts.

Operationally, the rifle utilizes the T8 gas system, which is based on the MWS design and provides realistic functions such as recoil and a reciprocating bolt. The internal components allow for adjustments to trigger travel and gas output, though the reviewer mentions a plastic buffer guide and the need for proper lubrication to ensure smooth cycling. During testing, the rifle demonstrated a high muzzle velocity and a fast rate of fire, though it required heavy BBs to manage the power output.

The Gear Locker says that this replica is a specialized option for historical reenactors and airsoft players focused on "clone" builds who may not have access to real firearms. Because gas blowback systems require more maintenance than battery-powered alternatives, the rifle is positioned for users seeking a tactile experience. He plans to further customize the piece to match specific 1980s mission specs in a future installment.
