This video discusses stoppages encountered with an AIM Surplus Gen3 Glock build. The primary issues reported were failures to extract, initially attributed to potential extractor spring tension, and later, random action locking to the rear, particularly when operating one-handed. The presenter replaced the plunger spring with an OEM Glock part to address the extraction failures.
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.
