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, T4 bars, rods, and a normal length K25 spring. All you will need is your choice of plunger tube lube.
Please note: My kits include 3 M3 rods and the related M3 nuts. This does not require any changes to the print. I have built all of mine without any metric changes. However, the metric shroud and back cap will be marginally easier to use if you are comfortable printing the relevant files.
