Finally bucked up and got a WOA-tuned RRA 2 Stage...
I don't vast 2 stage experience, but all I can say is this breaks NICE!

I do have few questions though:

Did anyone else have trouble with excess flash interfering with the trigger slot?
I made the decision to file it down the flash a tiny bit, but I'm not sure what to touch it up with?
cold blue? black nail polish?!

Finally, the supplied pins went in pretty easily...I thought they were a tad oversized?
I doubt they'll walk out, but I expected to have to give 'em a decent tap to get them in.
I'm wondering if my lower might be a hair out of spec.

Sorry for the ramble, just wanted to see if this is unusual or not...?

My pins were hard for me to get in on my WOA trigger on my RRA lower...other than that it was/is fine.

what trigger slot did you file down?

Oh, I didn't file the receiver, I just got rid if a bit of flash of the sides of the actual trigger.

So, one of two things was going on; either my lower (Ameetec) has a small trigger opening,
or the RRA trigger wasn't cleaned up enough.

It's weird, all my "low end" M1S stuff (trigger and my upper) fit a bit better than
my fancy CMMG and RRA stuff!


Whatever, it functions fine...it just surprised me.

Removing a bit of "flash" as you call it is not that uncommon. I have seen the same with the Jewell triggers. Some trigger wells are a bit tighter than others. Don't worry about it. You can cold blue if you want, personally I would not worry about it, it will be just fine.
