ShootingSight RPS AR15 Trigger Review

Written by: Buddy Murphy

This is a review of the ShootingSight RPS Trigger upgrade kit. This kit features a 2-stage trigger and hammer configuration, compatible with the AR-15 and other platforms that utilize similar pivot pin spacing. This trigger is considered a National Match trigger and should be compared to others like the Geissele’s National Match.

Should this hammer be black? No. That is carbon from heavy use suppressed in a direct impingement rifle. Does the trigger feel gritty? No, it is still very smooth.

The sear surfaces have been meticulously lapped to achieve ultimate smoothness and feature a Nickel Boron (NiB) coating. This makes the trigger highly resistant to wear and offers a low coefficient of friction, resulting in a smooth and consistent pull. Like most AR triggers, this is not adjustable.

Let me take you back to High School physics class. Static friction is greater than kinetic friction because static friction acts when the body is at rest. Whereas in kinetic friction, an object is in motion. You can feel this in the trigger. Once the trigger starts moving towards the second stage wall, it feels less heavy than when you start moving the trigger. The reset is very positive and is just beyond the second stage wall, but not fully out to the first stages at-rest position.

One of the standout aspects of these trigger/hammer sets is that they are CNC machined from alloy Rolled Plate Steel. Thus entirely avoiding the use of cast parts. The finer grain structure of this steel provides significantly greater tensile strength (about 10 to 20% stronger), better impact resistance, and less fatigue compared to cast steel. This allows for the sear edges to be precisely honed, resulting in an exceptionally crisp break that maintains its sharpness over heavy use.

This trigger installs like any mil-spec trigger, nothing proprietary (look at you cartridge triggers). Which makes it compatible with any lower that accepts mil-spec triggers.

Additionally, the RPS Trigger kit includes an extra powerful Wolff hammer spring, which delivers maximum ignition energy and an impressively fast lock-time of just 4 milliseconds. The second stage trigger creep has been virtually eliminated, ensuring a clean and crisp break with no felt travel in the second stage.

I use this rifle for CMP (Civilian Marksmanship Program) practice every weekend (unless I’m trying out a different rifle), so this trigger gets a lot of use. I can tell when I am using a different trigger, it just isn’t as smooth, and my scores can tell too.

The trigger pull weight is set at 4.5 (2.5/2.0) pounds, which meets the NRA/CMP minimum requirements for the Service Rifle class. Overall, the RPS Trigger upgrade kit is an excellent choice for those looking to enhance the performance and reliability of their rifle.
