Rock River NM 2 stage trigger review

[MrChicken]

After reading everything I could about triggers, here and other places I decided that a two stage is what I needed. I wanted a super crisp, light single stage trigger, but I also let other shooters use this this rifle in our weekly competitions so I decided that a two stage was probably best.

I wanted a lighter crisper trigger that a novice could handle. The RR NM 2 stage fits the bill perfectly. It's got noticable slack and a crisp break that I would guess is around 4-5lbs even though it feels lighter.

How much better is it than stock? 100% and totatlly different. I have the early model that does not have the "blue" springs. The stock trigger is heavy, gritty and the opposite of "crisp".

For comparison, the range had a new 15-22 with blue springs, the trigger in that gun was the same but a pound or two lighter than my stock trigger. I wonder how much lighter the JP yellow springs would make the stock trigger.

No change in ammo preference, it still does not like Winchester bulk, although all of the failures were mag snags. It still prefers the hotter ammo.

Thumbing the hammer back, the hammer spring in the RR kit feels lighter initially and heavier than the stock spring at full cock. The hammer hits hard, there'll be no misfires with this kit. Much like the stock trigger the reset is strong and loud.

Installation: 10 minutes tops. Thanks to Brett's videos that I had been through earlier, I took out the old parts, cleaned up the lower while I had it apart and installed the new trigger in about 10 minutes. There are no adjustments, it is a straight drop in kit. Easy peasy...

Got it from Brownells, $125 with USPS shipping, it arrived in two days.

Thanks for the review! I've been thinking about that very trigger for my M&P 15-22. You may have pushed me over the edge.

RRA triggers is all I run.

I have two of these triggers but did not put one in my 15-22. Seemed a needless expense after the "15 minute trigger job" and certainly good enough for my use chasing cans and shotgun hulls around the range.

My favorite trigger remains my Accuracy Speaks single stage, but the price has gotten out of hand on this one.

The liability issue of letting other people with limited experience use my rifle with a self modified trigger system was a concern.

My excuse to the wife for spending so much money on accessories is that I can move it to a real AR when I get one

Its easier to ask forgivness than permission, as long as you can talk yourself out of a divorce

Hmm, that seems pretty clear to me.

Ok, I dont want other people using my rifle that has the "15 minute trigger job" done on it. Them having a ND with the blame put on a "15 minute trigger job" would be something I don't want to deal with.

I can't understand how you didn't "get" what he said, considering how you preach against self modifying the trigger.

What he's saying is this.. "I bought the RRA trigger because I don't want to tweak my stock Mil Spec parts and have something go awry with someone else shooting my rifle"

Clear?

...Chuck is just being chuck don't worry bout him... great review and I hope it gives you years of flawless service

Can anyone explain the mechanics of how this trigger is different compared to the stock trigger? Just curious and trying to educate myself. Thanks.

Its a two stage trigger with a heaver than 4.5lb first stage followed by a nice crisp second stage break that is supposed to be lighter than the first. The 4.5lb minimum is required for service rifle competion and that is what the RRA 2 stage was designed for. I love mine and am glad I didn't cough up $275 for the Gissle

 

[idbstyler]

Thanks for the info. Is there a big difference between the this trigger and the stock?

The two stage triggers are a completely different design than the standard, single stage trigger. The sear is on the inverted Tee on the hammer, not the forward notch.

Here's the typical designs:

Two stage (Rock River).................................................................Single stage (Accuracy Speaks

I bought the RRA 2 stage match with my lower parts kit so I never got a chance to try out the standard trigger. For target shooting, if you want to be competative, you will need a match trigger. For shooting at can or just blasting away, it probably will not matter. I hope that helps.

 

[MrChicken]

FWIW, this trigger I installed has about 3/16ths take up of about 2.5-3lbs and then hard stop with a crisp 4-5lb break.
Weights measured by my uncalibrated finger...

 

[idbstyler]

Maybe someone can start a thread explaining the difference in triggers. I'm starting to learn more about them but there's still a lot out there that I don't know. I would like to upgrade my trigger but I'm still not for sure what I should be looking for. Anyone want to give me the low down on triggers?

 

[rebs081]

with the RRA NM 2 stage trigger, can you definitely feel the end of the first stage and know you are on the lighter crisper second stage ?

 

[Majorlk]

I don't know about the RR, but it's been that way on every Two-Stage trigger I have pulled.

 

[Mack]

The RR triggers are OK starting out but they wear out pretty fast (usually 3-6,000 rounds) and when they do they start to double. I prefer the Geissele SSA which will make it a full 10,000 rounds at which point it is time to replace the bolt, all the lower parts including the trigger and maybe the barrel. Any trigger you go with if after some wear it starts doubling I would not try to fix but replace at once as then you are in possession of an unregistered machine gun.
