This video provides two practical methods for assessing the quality of used firearms without specialized tools. The first tip emphasizes checking if all parts are original to the brand, as aftermarket modifications can be difficult to verify. The second tip focuses on estimating round count by examining barrel finish wear, with examples like the Glock 25 illustrating minimal wear on newer firearms. For AR-15s, it's recommended to prefer OEM builds over custom 'garage builds' and to inspect the bolt carrier group's interface with the hammer for signs of heavy use.

Quick Summary

To gauge used gun quality, check if all parts match the original brand, as aftermarket modifications can be hard to verify. Also, estimate round count by examining barrel finish wear; significant wear indicates higher usage. For AR-15s, prefer OEM builds and inspect the BCG for wear.

Frequently Asked Questions

What is the first practical tip for checking the quality of a used gun?

The first practical tip is to ensure all parts of the firearm match the original brand. While aftermarket parts can be fine, verifying their quality and proper installation is difficult for the average buyer.

How can you estimate the round count of a used firearm by looking at it?

You can estimate a used firearm's round count by examining the finish wear on the barrel. Firearms with a high round count will typically show significant finish wear on the barrel, especially near the muzzle and chamber.

What specific advice is given for inspecting used AR-15s?

For AR-15s, it's recommended to prefer firearms built by OEM manufacturers over custom 'garage builds'. Also, check the wear on the bottom of the Bolt Carrier Group (BCG) where it interfaces with the hammer.

What does wear on the Bolt Carrier Group (BCG) indicate on an AR-15?

Significant wear on the bottom of the AR-15's Bolt Carrier Group (BCG), where it contacts the hammer, indicates a high round count and extensive use. Cycling the action should feel smooth, not 'crunchy' or 'sloppy'.
