In this Suppressor 101 episode, Justin walks first-time owners through the key steps after buying a suppressor:

• How to mount it
• How to tune the firearm for suppressed use
• How to maintain it

He covers direct-thread vs fast-attach mounting, emphasizes never using a crush washer (use shims instead), and explains how to check alignment/concentricity with a rod (or a gunsmith). He then breaks down tuning methods like adjustable gas blocks, buffer weight/spring changes for AR-style rifles, and ways to reduce gas to the face (including gas-busting charging handles). Finally, he explains re-zeroing after adding a suppressor due to POI shift and outlines cleaning schedules: ~500 rounds for .22 LR, and ~3,000–5,000 rounds for most pistol/rifle cans, while stressing the importance of keeping mounting surfaces and threads clean for safe, secure lockup.
