Nice as that is, the triple tap is a very very expensive unit. I would personally recommend the pws fsc 556.
Nice rig, who makes the handguard?
looks only, or do you have a purpose for needing/wanting a new one?
Look at the Eliminator from ATRS. Have one on my rifle and love it.
S&J linear brake, with flutes to match your handguard holes?
