@troy fairweather - when looking at the 2 stage options for AR’s, be sure your needs and preference aligns with the trigger design.
I did a fairly detailed write up on 2 stage AR triggers here a while back covering the differences, but there really are two classes, heavy/light vs. light/heavy - with a “mid/mid” class in between, which I personally count in the light/heavy class.
Personally, I’m a heavy/light shooter. If a trigger is 2lbs total, I want a 1.5lb front end with an 8oz break. I don’t like triggers which are light up front and find a heavy wall - I want a smooth rolling trigger which “trips” over a light, candy cane break. Some guys want a safe trigger which feels more like a single stage bolt rifle trigger - a light slack take up plus a heavier break.
“Back in the day,” as they say, when there were far less options, and my funds were more limited, the Rock River NM/Varmint and the Bushmaster NM 2 stage were the affordable options beneath the Geissele. I favored the Bushmaster for many years despite a slightly higher price because I could reduce the second stage to under a pound, with the whole shebang just a touch over 2 - heavy/light. The Rock River is a Light/heavy with the first stage simply a slack spring take up followed by a 4lb break. I cut out the pins and replace the “disconnector spring” with a JP reduced power spring to reduce the second stage weight considerably - but they’re still much heavier in the second stage than the first when you keep them at a safe total weight.
RRA triggers also are not “drop in” triggers. They’re component triggers, such they do not require anti-walk pins. I don’t get too worked up over cartridge vs. component triggers. Most of mine are component because I like the Geisseles and the Bushmasters, and because the Rock Rivers are inexpensive (even though they aren’t my preferred type - still great triggers, especially for the money). TriggerTech and Elftman are cartridge types, I buy the anti walk pins and don’t worry.
So for someone jumping into these, I encourage folks to put a finger to both types and do some shooting before they decide which to adopt. Or at least, be sure your philosophy aligns with the trigger stage design.
