gnatshooter Posted June 15, 2014 Report Share Posted June 15, 2014 Friends, I am running a DPMS LR-308T and recently switched from the smooth-sided high-profile receiver to the low-profile receiver with forward assist. On the forward-facing side of the forward-assist housing, I am getting an accumulation of "brass dust" while shooting. It comes off easily with just a finger rub. At the same time, I am getting dents like this on all my spent brass. Click on the pic for a larger version: In the picture, the dent is the area on the shoulder, slightly on the left side of the picture, that looks like an inverted teardrop, or triangle. It's not a deep dent, but can easily be both seen and felt with a finger. First off, does this mean my rifle is overgassed, or something like that? I'm thinking the spent brass is hitting the forward assist housing on the way out, but it runs flawlessly. Second, is this spent brass reloadable, or is it toast?
