Description

This service is to remove the sear block or webbing from a lower to allow Geissele High Speed Triggers to properly fit your lower. Send your stripped lower. Stripped means STRIPPED, but you can leave the trigger guard in place, everything else needs to come off.

The $50 service will lower the shelf a bit to fit aftermarket triggers and remove the webbing in Colts as well as the Colt sear blocks.

The $80 service will lower the shelf to the bottom, and widen the sides to no specification. We don’t hold specific tolerances and it wont be pretty.

The $105 service will convert the lower to M16 Specs minus the hole.

There is no refinishing offered as part of this service.

A lower is a firearm, you must include a copy of a photo ID. The address on the photo ID is the address where we will return ship the firearm. No exceptions. We do not accept 80% lowers, or any type of personally made firearm. If you send us a lower without a serial number and proper markings – WE WILL DESTROY IT AND THROW IT IN THE TRASH. We will not engrave our info and serial number and send it back.
