For any of you guys out there that are hesitant to change out you trigger package, don't be. I just swapped the trigger in one of my Rock Rivers in to my ACR - I had never taken an AR trigger out before... and it was a piece of cake.
My ACR trigger was horrendous - coming in right at n i n e pounds! My Rock Rivers are great - nice and crisp and at about 4.5 lbs. I just couldn't wait for the Brownells delivery and was planning on some accuracy testing with a scope on the ACR today so I made the switch.
It took me all of about 15 minutes after viewing a few of the "how to" videos. Now I have a very nice 4.5 lb. pull ACR. Can't wait to get to the range with it.

The rock river trigger is great, I also swapped mine out with one the day I got my acr, best cheap mod for the platform imo

Yep, easy to do. I swapped mine out with an RRA before I sent it back for the recall, but was worried about going missing while it was back for the firing pin work so swapped it back. I think I'll order a Geisselle for it eventually but luckily my factory trigger wasn't too bad as-is.

I put a RRA trigger in mine also. Great trigger. Then I lost my mind and put in a Geissele SSA Trigger in because I love this rifle so much. I can't stop buying upgrades...

It a bonified disease, I think we all have it.

...i got a case of the upgrades too...and i got a question freddy...i read on some other forums that the hammer spring on the geissele 3gun trigger and maybe the ssa is shorter than the acr stock trigger spring...some had troubles with the install and some just used the stock spring instead...so is it true?...

...i've read people had problems with the spring on this forum as well and on youtube videos...some say it pops out but if you bend it a little it'll stay...would you bet your life on it?...

 

[DSM]

FWIW I used the stock ACR spring when I swapped to the RRA. It may have changed the pull of the trigger however slightly but it worked fine and was of course better than the factory unit.

 

[Freddy979]

I was lazy and kept the stock spring in there. I need to measure the trigger pull to see if it changed the pull weight from what is advertised for the trigger. It feels smooth though. I will look at the springs later today and see if they are different lengths.

yea man i'd like to hear if its true or not...if they're the same size i'll buy one right now....

 

[Freddy979]

Okay. I took my trigger assembly apart for you and verified that the spring lengths are the same. The Geissele springs are coated a nice shiny black too.

I'm new to the weapon upgrade world. Just so I'm totally clear, are you guys talking about the RRA national match trigger that fits receivers with a .154 hammer/trigger pins?

 

[Freddy979]

Yes. Any standard trigger will work.

I'm a noob at triggers, are all triggers standered or are some triggers special , and how do you tell the differance?

As far as AR triggers I guess I would class them into a few different categories. First would be plain Jane stock triggers like what you'd get in a generic parts kit or what the ACR has NIB currently. Second would be a 2-stage style like a Rock River or LMT or Geisselle combat trigger. Third would be more specialized triggers for match gunners like Jewell units. Of course there are subtle and not so subtle differences between any two triggers but I'd reckon that to be a decent break down.

A lighter trigger does not an accurate rifle make. The trigger is one component of the entire rifle. But a smooth trigger usually will help the shooter wring some more performance out of the rig but allowing less disturbance of the sights through the trigger pull.

 

[Avnwo]

Yes. Any standard trigger will work.

Thank you Freddy

So, how important is it that I swap out the spring from my stock trigger pack, to the one coming with my RRA 2 stage trigger? Is it noticeable? Any pics / tips on bending the spring to match the contour of the factory spring?

 

[Downrange]

I used the hammer spring from the alg defense kit. I bent it as similar to the acr spring as I could. However I feel the the detent arm could have a deeper pocket for the spring end.

Pretty much spot on DSM, also note a few things. Geisselle expects you to use the stock spring with the Super ACR, so I can assume it does not effect things to much, or he would supply what he feels is a proper replacement. 2- The 2 stage vs match most of the time just means a match trigger has adjustment for take up, over travel, and break. but they are almost always the same as the standard 2 stage component wise... and the RRA is a nice replacement.

I bent the spring that came with my Geissele SD-3G to basically the same as the stock spring. I can show a picture if you want, but you basically just need to duplicate the angle and location of the stock one. I just use pliers. It took several minutes to get the angle just right.

 

[ACR500]

I just used the stock spring with the SSA-E. it works flawlessly. I didnt want to chance it and try to bend it myself.
