Jinming M4A1 GEN 9 Gas Block

Works with my barrel interface and 16mm aluminium tube, allows any length external barrel and gas tube location, will also work with free float handguard assuming it clears the gas block.

Clamps around barrel and interfaces with the stock handguard if required, requires 3mm cap head screw and nyloc nut combo (20mm long) to tighten to barrel.

Printed in PLA but would be better in ABS or PETG.

Hopup isn't my design, excelent model can be found https://www.thingiverse.com/thing:3236970
