Barrel nut connector for Valken and Milsig M17 markers

thingiverse

This is a barrel nut replacement, not to connect a handguard, but to replace the threaded hex nut connectors where they have been lost, this joins two 10mm M5 button head nuts in the middle - i.e. the connectors that go through the marker to join various components like the magwell and handguard bolt. The item isn't threaded but an m5 bolt should thread itself on insertion, play with extrusion width if needed to make it snug.
