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.

The MK2 seems to be a well-built, American-made, adjustable and modular chassis. However, the standout feature of the MK2 is the absolutely phenomenal trigger these bullpups have due to the glass-smooth linkage of their trigger system.

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.

The MK2 chassis works with factory bolt releases, uses AICS magazines, is adjustable for comb height and LOP, has an ARCA rail, barricade stop, M-LOK slots, and ambidextrous safety on both sides of the trigger guard, a 20-MOA rail and uses AR15 grips. If you are looking for a way to get your Remington 700 or Tikka T3’s OAL a lot more compact while still having a phenomenal trigger, take a look at MK Machining. They also make some pretty cool throw levers as well.
