After 6.5 Grendel AR-15s are shot the sharp edges on the barrel extension are worn down by the brass cases. Granted magazine feed lips can scratch brass but with use the scratches from magazines and barrel extensions become less noticeable on the brass. The larger case diameter of the 6.5 Grendel always appeared to show the scratches and dings more than my 5.56 AR-15s.
There are forum members who smooth out the sharp barrel extensions to improve reliability and save wear and tear on their brass.
I have put about 2K rounds thru this barrel. SS has a really high hardness score I think this thing will last a really long time. so, that being said I took a minifile to the lugs to soften em up a bit. Remember fellas the file only werx in one direction. :p
