Before SHOT 2023, I was tipped off by a co-worker who knew that I was a Tikka fan that a company was bringing a bullpup chassis and optimized bullpup trigger for the Tikka to SHOT. That company is MK Machining of Hallsville, MO. One of the few bright lights in the otherwise dingy SHOT Dungeon was MK Machining’s MK2 Bullpup Chassis, which is now available for Remington 700 short and long actions, as well as Tikka T3 actions.

[SHOT 2023] MK Machining’s MK2 Bullpup Chassis and Amazingly Good Bullpup Trigger
According to a company rep, the lead designer of the MK2 was told by industry colleagues to give up on trying to create the perfect light bullpup trigger, as it couldn’t be done. He took that as a challenge, and I daresay he succeeded. At the heart of the MK2’s trigger is a custom Timmy Calvin Elite single stage trigger. What makes the trigger able to release the sear so crisply and with such a light pull is the patent-pending linkage.
The linkage reminded me somewhat of the throttle linkages I have seen. Pulling the Timmy trigger moves two parallel rods in opposite directions. These rods are connected to a pivoting actuator on a secondary trigger box underneath the sear. The result is a bullpup with an amazingly good trigger. The trigger is also adjustable for pull weight without disassembly of the chassis via a cut in the trigger guard.

It looks cool and high quality, but I can't imagine how ergonomically frustrating and uncomfortable it would be to throw a bolt back and forth near your shoulder.
A semiauto bullpup is one thing, but this is ridiculous. The bolt handle is right below your eye when locked, and then you have to pull it all the way back to your ear to chamber another round? What is this, archery?
