About this model
This is a handguard I've added for the design of my Sig MCX upper receiver kit that fits onto a Specna Arms M4 lower receiver (available here: ). The linked design features a rattler-esque handguard. You will need an external barrel extender (I've included one with the files above, but again, tolerances and print settings vary the results greatly - I recommend a layer height of 0.12 at most so that the threads print well. I print this vertically, in PLA+ with minimum of 6 walls - infill can be 50%. This design is a work in progress, and may require some small edits to fit, especially with the varying tolerances of different printers. As always, this is for a 6mm airsoft rifle, NOT A REAL WEAPON. Do not attempt to alter this for use with anything other than it's intended use..
