This video from AT3 Tactical explains why Inconel, a chromium-nickel alloy, is not typically used for rifle barrels. Despite its excellent heat erosion resistance, making it common in suppressors, its extreme weight, difficulty in machining, and high cost render it impractical for standard barrel lengths. The expert speaker highlights these manufacturing constraints.
This guide details the disassembly of the SilencerCo Maxim 9, an integrally suppressed pistol, based on expert analysis from Forgotten Weapons. It covers the unique delayed blowback action, the slide and frame mechanics, and the modular suppressor system, emphasizing the importance of proper firearm handling during disassembly.
This video from Washington Gun Law TV, hosted by William Kirk, details the ATF's proposed rule changes that significantly expand definitions of firearm components and increase regulatory burdens. The proposed rule aims to bring more firearms and parts under federal control by redefining 'frame or receiver,' 'firearm,' and 'gunsmith.' It also imposes stricter marking, serialization, and record-keeping requirements on manufacturers, importers, and Federal Firearms Licensees (FFLs), particularly impacting privately made firearms (PMFs) and firearm parts kits.
The ATF has proposed rule 2021R05, aiming to redefine 'frame or receiver' to include any externally visible housing or holding structure for one or more fire control components, or any part with slide rails. This redefinition would classify many incomplete firearm frames, commonly known as 80% receivers, and certain firearm parts kits as firearms, requiring serialization and regulation. The proposed rule also expands the definition to include parts of silencers disposed of separately and could impact solvent traps. The video emphasizes the importance of public comment on this proposed rule.
