Frequently Asked Questions

What are the main components of a rifle trigger?

A rifle trigger typically consists of the trigger housing, the trigger itself, the sear, adjustment screws, springs, and a safety mechanism. These parts require high precision manufacturing and assembly for optimal rifle accuracy.

How is a Gunwerks rifle trigger assembled?

The assembly involves press-fitting housing plates and adjustment blocks with oversized pins using a hydraulic press, followed by installing the trigger and sear. Critical adjustments for pull weight, overtravel, and sear engagement are then made.

What is the purpose of a Trigger Scan device?

A Trigger Scan device analyzes the force and movement during a trigger pull, generating a force-travel chart. This data is used to verify that the trigger meets specific performance profiles required for precision shooting.

What adjustable parameters are key for rifle trigger tuning?

Key adjustable parameters for rifle triggers include the weight of pull, the amount of overtravel after the break, and the sear engagement. Proper adjustment of these is crucial for accuracy and a crisp trigger break.
