Rough, scratches and noisey
I bought two (2) of these for rifle builds. Both sound and feel like the buffer is being pulled across a cheese grater. The buffer and spring are okay. I swapped the buffer & springs from various rifle, and it is definitely the tube causing the rough performance. These are supposed to be 7075. Maybe, but they are rough. After a couple of range trips, nothing has changed.
