A mashup of Silent Night and the Zinc grip: Zilent Night. Takes Zinc magazines (though it only works with the 10 and 13-round mags because the "chamber" is much higher up on Silent Night than the zinc, so in order to be able to grab the magazine back out, it needs to be longer than the standard 7-round mag. Uses friction and a compliant mechanism to hold the mag in place. Like Silent Night, the only hardware needed is the 1/8" bungee cord. The trigger is held in place with a piece of non-extruded 1.75mm filament.Hits mid-90 FPS with AF Pro / DZ Max / Worker darts. Does not play nice with cut-down accustrike or waffle-head darts. For best results, the "correct" tension is found by stringing it with the slide forward and the string forward (like in the picture), and putting a very light preload on it. That'll allow the cord to stretch back and give a good fling to the dart.
