Description
A 3D-printed adaptor that works as both a handguard retaining nut and a 18mm+ to 14mm- adaptor.
This was originally designed to allow use of standard 14mm- outer barrel extensions in a BET or carbine EVO – a 4″ M4 barrel extension on top of this adaptor will put the muzzle just at the end of the BET/Carbine handguard.
