Adjustable Aluminum Trigger
The SierraPapa trigger upgrade is manufactured in the USA from 6061 grade aluminum. After machining, the trigger is anodized to provide a durable, non-reflective finish.
This replacement trigger is stronger and less flexible than the original CX4 plastic trigger, and features an adjustment screw that removes much of the objectionable pre-travel found in the original trigger group. The new trigger also features a permanently installed pivot pin for attachment of the first trigger operating bar. This ensures less flex in the trigger movement. Additionally, the slightly larger diameter of this fixed pivot pin removes some of the slack in the trigger movement.
The trigger is engraved "SP USA" to demonstrate BATFE Part 922R compliance.
For best overall results the trigger upgrade should be installed concurrently with our stainless steel hammer and reduced power hammer spring upgrades.
