I created this fixture to store and/or test the fire control group (trigger/hammer/sear/safety) for AR-style receivers. It can be used for troubleshooting issues, and for training purposes to demonstrate how the parts all interact.
I've tested it with both mil-spec and drop-in trigger groups, and single/multi-piece safeties, but it may require fitting for other particular or non-standard parts.
Recommended Print Settings:
Main Body Material - PETG, Perimeters - 3 (or more), Infill - 75% (or greater)
Hammer Stop Material - TPU, Infill - 100%
Required Hardware - 2 each of M4 x 50mm Socket Head Bolts and 4mm Nuts
Note: This is not a firearm - This model is designed for testing parts only!
