This review details the Norinco M305A, an M14 variant chambered in 7.62x39mm, notable for its compatibility with standard AK magazines. Externally, it closely resembles a traditional M14, with internal modifications focused on the magazine well and fire control group to accept the smaller cartridge. The rifle represents a unique convergence of M14 and AK platforms, specifically adapted for the Canadian market.

This expert-level explanation from Forgotten Weapons details the historical methods of converting semi-automatic Uzis to full-automatic fire in the US before the 1986 ban. It covers the 'registered bolt' and 'registered receiver' techniques, emphasizing the legal implications of modifying or registering specific firearm components. The instruction highlights the critical role of pre-1986 laws in allowing these conversions.

This expert guide, presented by Ian McCollum of Forgotten Weapons, details the legal intricacies of using transferable H&K auto sears with semi-auto host firearms. It emphasizes that modifying the receiver's semi-auto shelf is illegal, and instead, the trigger pack housing must be modified to fit. The guide covers crucial purchase precautions and potential legal pitfalls, particularly for MP5 conversions.

This video details a non-factory safety modification commonly found on German inter-war police submachine guns, particularly the Erma EMP. Unlike standard open-bolt safeties, this system locks the bolt in the forward, closed position, allowing for safer carry with a loaded magazine. The modification involves cutting slots into the receiver and bolt, and attaching a lever-based safety unit.
