Testing

There are two primary requirements in this test to verify the analysis. The first being a function test and the second a measurement of trigger break weights.

 

This will be a straightforward test using commercially available and inexpensive equipment. The desired requirement for trigger weight reduction is between 1lbf and 1.5lbf.

​

Function: After installation the device must be verified to be unfireable in the safe selector position as well as being capable of firing in both of the fire positions.

 

Break Weight: Using a commercially available trigger pull gauge a series of samples will be taken of both the Mil Spec and SSA Triggers. These samples will be overlaid with the advertised break force graph and calculated theoretical value. This will provide a three point technical baseline giving a high degree of precision. This will then be performed for both modes of the new trigger design and will also be compared to the calculated theoretical values.
