Chance saw the Rush and said "This is great but what if I changed basically everything?" and the Crush was born. The Crush uses heat inserts, a linear rail, and an optional quick-release stock giving it a very premium feel. Other notable changes from the Rush include straight talon mags, a smaller grip, and a more compact feel.
DIY will include fasteners, 11 inch barrel, plunger tube, rush bars(not T4), rods, and both a normal length K25 spring and a lower power 5 inch 788 spring. All you will need is your choice of plunger tube lube.
