This video highlights a significant issue with an AIM Surplus Gen3 Glock barrel, where the 416R stainless steel appears to be excessively wearing and 'eating itself alive.' The instructor notes that this level of aggressive material removal is not seen on OEM Glock barrels with significantly higher round counts, suggesting the AIM Surplus barrel is extremely soft due to improper heat treatment. The slide is unaffected, further indicating the barrel's material deficiency.
