u/Impressive-Bench-982

Just got back from shooting my brand new gen 2 ace in 5.56 and I noticed some significant scratching on the bolt already. After around 120 rounds of .223 and 20 rounds of 5.56 this was the result.

Is this normal wear and tear or is it potentially not lubricated properly? I cleaned off all of the factory grease and used hoppes gun oil to lubricate bolt group and rails before shooting.

Please let me know if I should be concerned or not. There were zero malfunctions at the range.
