Introducing a drop-in polymer block, crafted to provide a true feel of trigger movement and pull weight without risking thumb injury.

Feel free to drop the hammer! This shock-absorbing block stops the hammer from striking the magazine well wall, preventing expensive receiver damage and broken hammers.

Designed to fit into the magazine well with the upper receiver, it specifically protects the lower receiver when testing the function of a newly installed hammer and trigger. The block locks securely into place and can be easily removed by pressing the magazine release.
