Airsoft Artisan DD416 -type handguard kit
 
The DD416 handguard... this should be on all DEVGRU-inspired HK416 builds period.
 
Definitely a unique look & approach towards functionality and miles ahead of its time - before MLOK/Keymod were the norms, this was the "modularity" evolution from your typical picatinny rails. 
 
This will fit WE, VFC, Umarex HK416 AEGs & GBBRs. If you need it for Marui, please drop a note in the order, so we send you the barrel nut for the Marui for free.
 
Notes:
Made from 6 series aluminium.
CNC metal construction.
Anodized color finish.
Set includes two 7 slot rail panels, 1 barrel nut, and 1 handguard locking screw.
