Default RRA National Match Trigger - Failure and Repair

I don't know if anyone here has had an issue with their RRA NM trigger, but I thought I'd post a link just in case my video on the subject might be helpful.

Not uncommon for the springs to relax and then the trigger not make weight. Have had to help competitors disassemble and bend springs on more than a few occasions in order to make weight at an EIC match.

My loaner rifle has a RRA NM trigger. After a year or two it just stopped making weight one day. I ended up using a JP Enterprises SR spring kit and stoning a few of the surfaces and now it's one of my favorite triggers.

Just to frame the issue....no other manufacturer trigger with use ends up failing the weight test ? Rock River is the only trigger with this trend ?

Just curious...how many rounds fired till this phenomena begins to show up ?

Sorry, but I canít answer your question. The video I made about my trigger had nothing to do with it failing to make weight. Iím not entirely sure how that topic became part of this conversation.

I have a RRA 2-stage in my match rifle. I actually like it better than my Geissele triggers. BUT....it won't make the 4.5# for SR. It will make the 3.5# for match rifle though.

If you contact RRA, they should be able to rectify that trigger for you. Thereís a good chance you got the springs for the (3.5 lb) varmint trigger.

Just put a very small bend in the hammer spring legs increasing the tension and it will correct the low trigger pull. My RRA NM trigger was under 4.5# right out of the bag. A slight bend and it has remained just under 5# since. Failure to reset is often caused byva burr that can develop. I had one that wouldn't right out of the bag. A tiny but of work with a stone and it was good to go. That one has about 10K rounds to it's credit varmint hunting.
