This video from Brownells Gun Techs debunks the myth that you cannot "over-clean" a gun. While cleaning won't wear out a firearm, disassembling it too often for cleaning can shorten its service life due to wear on pins and screws. For modern polymer pistols, hosing them down with cleaner is sufficient. Older firearms like the Colt 1911, M1 Garand, and AR-15 are designed for regular disassembly, but care should be taken not to lose small parts. The video also touches on barrel cleaning for precision shooting and the clean-burning nature of modern .22 LR ammo.
This "Smythbusters" video from Brownells debunks the myth that AR-15 rear sights from different manufacturers are not interchangeable. Gunsmiths Steve Ostrem and Caleb Savant explain that AR-15 rear sights are manufactured to a standard height, ensuring compatibility. They clarify that if a current rear sight works with a front sight, a replacement will also work. The video highlights the AR-15's versatility through easy parts interchangeability but cautions that this applies to current production models, with variations existing in older or retro reproductions. Viewers are encouraged to leave comments with questions or exceptions to this rule.
