AR-15 Trigger Test Block
thingiverse
Test an AR lower with standard trigger without risking damage to the lower. This one has been thoroughly tested in four lowers, each equipped with a different trigger variant, and has had its hammer dropped over 500 times. The angled hammer face disperses force across a broader area for added durability. A small amount of looseness is incorporated into the AR design to accommodate minor printing imperfections.

This design was inspired by PrintedFirearm's innovative AR-15 Trigger Pull Test Block, available on Thingiverse (https://www.thingiverse.com/thing:991599).
