This Brownells maintenance guide provides a comprehensive cleaning and lubrication tutorial for AK-pattern rifles, using a Zastava M70 as the example. Host Caleb details field stripping, safe cleaning of the barrel, bolt, gas system, and receiver. The video covers essential cleaning supplies like CLP, steel wool, and bronze brushes, along with specialized lubricants for AK heat resistance. It also addresses common issues such as stuck firing pins and carbon buildup, offering practical tips for maintaining AK reliability and longevity without overcomplication.
This 'Smyth Busters' video debunks the myth that bronze bore brushes damage steel gun barrels. The hosts explain that soft bronze is unlikely to harm modern steel, though very old barrels or excessive force with abrasive powder residue could cause wear. They also caution against bronze brushes with steel cores scratching muzzle crowns and recommend brass cores for extra safety. The video suggests that damaged rifling might stem from improper cleaning techniques, such as using a steel rod in a .22 rimfire or excessive drilling with a brush on a dry bore. The myth is declared busted, with advice to use good solvents, nylon brushes, bore guides, and care with steel rods.
