Frequently Asked Questions

What are the main benefits of the Rise Armament SST-140 trigger over a mil-spec trigger?

The Rise Armament SST-140 offers a smoother pull, shorter pull length, a crisper break, and a significantly shorter reset compared to standard mil-spec triggers. It also provides a lighter pull weight, typically around 3 lbs, enhancing overall shooting feel and control.

What is the typical trigger pull weight for the Rise Armament SST-140?

During testing, the Rise Armament SST-140 consistently broke around 3 pounds, with measurements showing slight variations up to 3 pounds and 4 ounces. This consistent, light pull weight contributes to improved accuracy and faster follow-up shots.

How easy is the Rise Armament SST-140 to install?

The SST-140 is a one-piece drop-in trigger unit, which generally makes it easier to install than traditional mil-spec trigger assemblies that involve separate springs and components. This design simplifies the modification process for many AR-15 owners.

What are KNS Precision anti-walk pins used for with AR-15 triggers?

KNS Precision anti-walk pins are used to secure the trigger and hammer pins in an AR-15 lower receiver. They prevent the pins from walking out during recoil, which is especially important with lighter trigger pulls and can help maintain consistent trigger function and prevent potential damage.
