M-Lok Handguard for Airsoft M4

thingiverse

This is strictly for Airsoft use only! Don't even think about trying it out on a real rifle, as it will not withstand the intense stresses of a live firearm. I'm not responsible if you end up shooting yourself in the foot. I tested this design on my Classic Army M4 and got it to work, but I make no promises that it'll fit your other rifles. To be safe, start by printing just the barrel nut and see how it fits. If that works out, then try attaching the handguard to the barrel nut with minimal post-print sanding required. The nuts on the handguard are designed for M6 fasteners.
