This SmythBusters episode tackles five common myths surrounding AR-15 rifle builds. The video debunks misconceptions about using reaction rods, the state of raw aluminum after lapping, gas block alignment, clamping the barrel for muzzle device installation, and the practice of using a torque wrench for barrel nut removal. Key takeaways include alternative methods to reaction rods, the protective benefits of grease on lapped aluminum, the forgiving nature of gas port hole sizing, the acceptability of clamping for muzzle device work, and that torque wrenches are not ruined by barrel nut removal. The video aims to educate viewers and set the record straight on these building practices.

This video details the installation of a Geissele MK8 Super Modular Rail on an AR-15. Key steps include using a Geissele Reaction Rod for upper receiver stability, proper torquing of the proprietary barrel nut, and secure installation of the gas block and tube. The rail is then slid on and secured with two cross-bolts using a T-handle hex wrench. Final steps involve muzzle device installation and a thorough inspection.

Proper ammunition storage is crucial for maintaining reliability and safety. Avoid storing ammo in cardboard boxes in damp environments, as this leads to moisture absorption and corrosion. Utilize airtight containers like ammo cans and control humidity with desiccants like silica gel packs. Heat accelerates gunpowder and primer degradation, so store ammo at stable room temperatures. Reloading primers are particularly vulnerable to moisture and require strict airtight storage.

This video demonstrates how to upgrade an AR-15's A2 furniture to Magpul components. It details the removal of the A2 grip using a Bondhus hex set and the installation of a Magpul MIAD grip with interchangeable backstraps for improved ergonomics.
