There are multiple accounts of shermans being captured by german troops and used against the US forces. I don't doubt that US rifles were captured and used as well, but that would not be as obvious to a foot soldier, as a captured tank coming your way. So it is less likely to be documented. I think the only way we will ever know, is to find photos like the one shown above.
BTW HillBilly Burgett's books are excellent reads. If you want a better overview of the battle of the bulge, read "The Battered Bastards of Bastogne" by George E Koskimaki. It is not an account by one person, but by many.
