interlock

An interlock is a feature that makes the state of two mechanisms or functions mutually dependent. It may be used to prevent undesired states in a finite-state machine, and may consist of any electrical, electronic, or mechanical devices or systems. In most applications, an interlock is used to help prevent a machine from harming its operator or damaging itself by preventing one element from changing state due to the state of another element, and vice versa. Elevators are equipped with an interlock that prevents the moving elevator from opening its doors, and prevents the stationary elevator (with open doors) from moving. Interlocks may include sophisticated elements such as curtains of infrared beams, photodetectors, a computer containing an interlocking computer program, digital or analogue electronics, or simple switches and locks.

    I wound up getting these and realized they're a bit too big for my guns. Apparently these fit the 22 Savage Hi-Power, aka 5.6x52mmR, and are no longer in production. I'd like to get $50/box, or $90 for the pair. Or I'd trade them for Hornady Sub-X rounds in 308, 357, or 458. Or would trade...
