Eclipse GEO IV Core Kit

The IVCore bolt assembly is the drivetrain for both the legendary Eclipse GSL along with the new GEO3.5 and is now available as a retro-fit upgrade for all GEO marker models. The IVCore brings about not only a significant uplift in outright efficiency to the GEO, but also noted improvements in both feel and sound signature. The new breech-sensing technology in the IVCore further compliments the drivetrains design adding consistency and readability to the already revolutionary design!

The IVCore is quick and easy to install to all of the following GEO markers: GEO, GEO+, SL91, GEO2, GEO2.1, GEO3 and GEO3.1
