The combat rifle is capable of filling various roles depending on its configuration, such as a close-quarters automatic or a precision sniper. It is also chambered for .45 rounds, one of the most abundant forms of ammunition in the game. With higher ranks of Gun Nut, caliber conversions to the weaker .38 rounds and more powerful .308 rounds become available.

- Despite being chambered for a handgun caliber by default, there are always rifle cartridges seen in the magazine when reloading, suggesting the combat rifle was originally chambered for either .308 or 5.56mm, and was switched to the more abundant .45 round at the last minute in development. This makes it a rather curious weapon, being a large-caliber rifle that fires pistol rounds in two of its three configurations. Only a select few weapons in the Fallout universe share this kind of oddity, like That Gun and its regular counterpart for instance, which are pistols that fire rifle rounds.
- The combat rifle makes the best use of .45 rounds, boasting the highest damage for those calibers out of all other weapons that utilize them as well.
