I just traded my stock trigger springs out on my RRA A4 for a set of lighter wolf springs. I take it out back and test fire it. Bang. Next shot, nothing. I had to reset the safety to get it to fire again. Done so for te next 4 shots. Take back inside, take apart, check everything. All seems good. Take back outside, same thing. Put stock springs back, good to go!! WTF!!!!!! Any ideas? I must add that the rifle is set up with a stage 2 target trigger.

I called Wolf last week and come to find out that they do not recommend nor have any springs to trade them out with. Nothing they can do!!!

Per OP request, topic moved to this forum so it hopefully gets more views and responses.

How does the trigger behave when you pull it without the upper installed? Is there any binding? Did the spring set feel like it lightened the trigger? If you set the new spring next to the old one, is the deflection angle increased slightly (i.e. a lighter spring set needs at least the same, if not more, preload to reset properly).

If all you have to do is reset the safety on and off, then it will fire, then the hammer is obviously engaging the disconnector, but it must not be re-engaging the sear. That's where I'd be looking. One reason for that might be that the trigger isn't resetting completely forward, so either the spring isn't indexed properly, or it's binding, dragging, etc. OR, the trigger return spring isn't strong enough to reset on its own. You might be able to increase the pre-load on the spring by either bending it or blocking it. Might lube the pins, or even give them a shot with some polishing compound. I rub polishing/lapping compound on pins, then spin them in the trigger to help polish the inside of the pin hole as well, then spray it out with lube, to help ensure the trigger is 100% free. Not sure this could happen with an RRA or not, but it also might be that the disconnector is binding in the trigger so it can't release the hammer to engage on the trigger, so when the trigger resets, it's not releasing to mate the sear.

I'm not as familiar with the RRA 2 stage as I am with some of the other triggers out there, but that's where I would start. Play with the lower without the upper installed. Can't just put it together, have it not go bang, and not dig into what the root cause would be.

Hey NoMercy, AR's are for sure not my speciality as are bolt guns. I am forwarding this to my AR'smith and let him have at it. Thanks and will let ya know what happens.

Be sure you do!

The AR was designed to be "grunt friendly," but units still have an armourer.

Here's a brand new concept.
If it ain't broke don't try and fix it.

A crappy trigger is broken... (100% qualifying that heavy = crappy). Not saying I've ever seen an RRA 2 stage that was "crappy", just might need some tweaking on this one.

Thank you!!! And BullCamp82834, if you don't know what a crisp, clean, precise trigger can do for you, then I guess you wouldn't know till you did. And after years of shooting full blown, tricked out, benchrest rifles with the best triggers you can buy or build or my various other rifles with slicked up trigger systems. I work on our weapons at work all the time, thats what I do. BUT, this type of tweaking is not in my realm of expertise of amourering.

Then to come to this, pardon the pun, "Grunt Friendly" to a slightly higher plane, I was rather disappointed. Point, to make it better to my standards, yes, it is broke and needs fixing!!!!
