Tandemkross GearBox for Browning® Buck Mark

At a glance:

• Upgraded sear spring lowers trigger pull weight by .5lbs or more!*
• Installation frame houses spring for easy installation and consistent sear engagement
• No need to experiment with DIY spring fixes - one simple drop-in replacement!

The Browning Buck Mark has a great trigger right out of the box. But if you're like many Browning Buck Mark owners, you've likely researched ways to lower the gun's trigger pull weight and adjust the feel even further.

There are many DIY solutions out there, including the well-known "Heggis Flip" or Buck Mark sear spring flip. But these solutions can be complicated to perform, provide inconsistent results and can cause potentially dangerous issues with the fire control system.

Put an end to DIY fixes with the new GearBox for Browning Buck Mark from TANDEMKROSS! The GearBox is a simple, drop-in replacement for the factory Buck Mark sear spring that makes installation easier and lightens the trigger pull weight.

The GearBox comes complete with a redesigned torsion spring housed in a polymer installation frame. The frame captures the spring for easy installation and then, once installed, works as a guide for the spring, ensuring proper alignment and consistent engagement with the sear.

Pair with the Victory Trigger for maximum performance.
