I assume you mean the long, rectangular piece? That is the main structure of the launcher. It holds the barrel and the trigger group bolts to it. He plans machine it down as small as pissible and mount the throw levers right to it and get it tighter to the handguard. It will never be as close to the barrel as an M203 due to the fact it is being mounted to an RIS.why is there that piece that takes up so much space between the handguard and the launcher?
Are you looking to actually shoot it, or just the LCF or evil look?black_bear said:...why is there that piece that takes up so much space between the handguard and the launcher?
