If the dovetail screws into a "threaded insert," why couldn't 3R offer a thumbscrew of the same size, length, and threadHello,
we thank you first for your interest in our products.
No, it is not possible to replace the ilf dovetail with a DAS fitting or an old Hoyt style fitting, and we can not make the limbs with a standard ILF fiiting.
The ILF dove tail has six sides to be screwed with a spanner because it is a threaded insert.
Remove the ILF dovetail, screw in the DAS thumb screw.
It might actually be easier than swapping out bushings.
