Randy from AT3 Tactical provides an expert-level guide on properly aligning an AR-15 gas block, crucial for reliable cycling. The tutorial details necessary tools, including hex keys and Loctite, and outlines a step-by-step process for both dimpled and non-dimpled barrels. It emphasizes visual alignment checks using the handguard and barrel markings to ensure the gas port, gas block, and gas tube are perfectly synchronized, preventing future cycling issues.

This video debunks the 'direct impingement' myth for AR systems, explaining they use an internal gas piston within the bolt carrier. It details how gas travels via a tube and key, acting on the carrier and bolt head to cycle the action. The explanation covers bolt unlocking, gas venting, and how bolt carrier mass regulates cycling speed, while also addressing fouling concerns.
