The Air Force adopted the Model 630 or Model 649 under as GAU-5A/A. Army adopted the Model 629 Commando under as XM177E2. The Model 629 and Model 649 has longer barrels and Model 629 has a forward assist while the Model 649 does not. Army adopted the Model 609 under as Submachine Gun, 5.56 mm, XM177E1.

The Model 609 has a forward assist while the Model 610 does not have one. The Model 607A was made with XM16E1 receiver with forward assist and a standard pistol grip. The Model 607 CAR-15 Submachine Gun was a compact weapon with the first models made with M16 receivers without the forward assists and a shortened pistol grips from the CAR-15 Survival Rifles. The burst cam on the Model 605B could be modified to two-round or six-round burst. The Model 605B had no forward assist, but had a four-position selector switch which has a 360 degrees motion that could move clockwise or counterclockwise. The Model 605A CAR-15 Carbine was a shortened version that can be brought aboard in vehicles or helicopters.

For example, 9Г—19mm refers to a bore diameter being 9mm and has an overall case length of 19mm. The second number reflects the case length in inches or millimeters but again, usually measured in millimeters. The first number reflects the bore diameter in inches or millimeters but usually measured in millimeters. The two numbers used in cartridge names are the length for modern cartridges. This list can also be use to find firearms base on the AR platform for your OC to use (though most of them are not that unique by external design but most are unique in mechanical design and/or cartridges use). This is here for assisting with distinguishing AR-15/M16 platform from very known based firearms such as the M4, M16, and the HK416 along with additional information (I will improve this list over time).
