This Seat and #650 are required to fit the Megamouth to an Osprey or Other Lever Bows. Impale Archery continues to challenge the status quo with the new IA-1.  This new Seat IA-1 along with the #650 adapter allows a picatinny reel, like the Megamouth, to be mounted.  The ability to use the seat with either a spincast or picatinny reel make this the ultimate choice for versatility.  The IA-1 is machined from a single piece of T6-6061 aluminum.  The sleek cutouts, modular angles, strength, durability and compatibility with picatinny reels set this reel seat apart.  The IA-1 with adapter weighs a mere 5.4 ounces and offers for adjustability forward and back.  Both the IA-1 and REVO include a line management system, making them a single solution that eliminates twisting and turning between components.  The overall length of the IA-1 is 9.75” and comes with all necessary stainless steel mounting hardware included.  Reel not included.
