The Neptonics Systems Tuna mech is awesome! The housing is machined out of solid stainless steel and has fully rounded ends making it a breeze to install. You no longer have to square the ends of your pocket! The updated internal components have new geometry for an even nicer, smoother release. This mech is strong and durable. It will accept shaft sizes: 9/32 5/16 11/32 & 3/8. Stainless steel pins and line release are included.
