The video opens with a discussion about choosing between an M4 and an M16, leading into the Anderson AM-15 Dissipator as a hybrid-style option. The rifle uses a 16-inch barrel paired with a rifle-length handguard, giving it the profile of a full-size M16 while keeping overall length closer to a carbine. The hosts compare it visually to a traditional M16 with a 20-inch barrel and explain that the front end of the Dissipator looks different because of the shorter barrel under full-length furniture. They note that this model is a new entry in Anderson’s retro line of rifles, intended to evoke classic M16-style configurations while offering a more compact package.
The hosts explain that the Dissipator concept dates back to the Vietnam War. Troops issued M16 rifles sometimes cut barrels down to around 16 inches to move more easily through dense brush and reduce weight at the muzzle, while retaining the rifle-length gas system and handguards. Those early cut-down rifles often suffered cycling issues because shortening the barrel reduced dwell time, the interval between the bullet passing the gas port and exiting the muzzle. To address this, Anderson slightly enlarges the gas port on the AM-15 Dissipator to capture more gas within the available dwell time. The dwell time on this 16-inch barrel is described as roughly equivalent to that of a 10.5-inch barrel, and the hosts state that this tuning allows the rifle to cycle very reliably.
To evaluate reliability, one host runs two full magazines through the Anderson AM-15 Dissipator in quick succession. The goal is to see how consistently the rifle cycles with the gas port positioned relatively close to the muzzle on the 16-inch barrel. During the rapid fire, the rifle appears to function without malfunctions, and the hosts observe that the ejection pattern looks consistent. They emphasize that the gas system seems well tuned, with the rifle cycling smoothly despite the shorter dwell time associated with the Dissipator layout. This initial test suggests that Anderson’s adjustments to gas port size and system setup are effective for sustained firing.
After the first shooting sequence, one host returns with a detachable carry handle installed to complete the retro aesthetic and take advantage of the long iron sight radius. The rifle is shown with flip-up sights as well, but the carry handle is highlighted as a more period-correct choice for this configuration. The host also points out a different cut on the bolt carrier. Anderson is described as transitioning to this alternative mil-spec approved bolt carrier design, which includes a profile intended to act as a scraper to help keep the carrier area cleaner during operation. With the carry handle mounted and the updated bolt carrier in place, the host conducts additional firing to confirm that the rifle continues to run reliably.
The hosts discuss how the long rifle-length handguard on the Anderson Dissipator provides ample space to place the support hand wherever it feels most natural. They note that shooters can grip far out toward the front or closer in, thanks to the extended real estate. At the same time, the shorter 16-inch barrel removes some weight from the muzzle compared to a traditional 20-inch M16, reducing fatigue during extended shooting. The configuration is said to appeal especially to those who prefer iron sights, since the long sight radius is a key benefit of the design. The hosts remark that adding a red dot would somewhat defeat the purpose of pushing the front sight and gas block so far forward on this retro-style rifle.
To further evaluate the rifle in a practical context, the hosts set up a friendly timed competition using the Anderson Dissipator. The course of fire consists of 10 rounds on a target at approximately 25 yards, then 10 rounds at about 75 yards, followed by 5 rounds back at 25 yards, for a total of 25 rounds. A shot timer is used to record overall time, and they also track misses. One host completes the course in about 23 seconds with several misses, while the other finishes in roughly 28 seconds with more misses. They acknowledge the hit counts and times without exaggeration, using the drill primarily to show how the rifle handles transitions between distances and sustained strings of fire.
In closing, the hosts reiterate that the Anderson Dissipator is a notable addition to Anderson’s retro line, combining a long handguard and sight radius with reduced front-end weight. They mention discussing suppressor use with Anderson and relay that, according to the manufacturer, the long gas system and relatively short dwell time help prevent the rifle from becoming excessively overgassed when a suppressor is attached. Even with the added back pressure of a suppressor, the system is not expected to run harshly. The hosts emphasize that they were pleasantly surprised by how well the rifle cycles in its unsuppressed configuration and indicate interest in shooting it more, including in suppressed setups, to further observe its behavior.
