I recently purchased a Mini-14 (583*) and have a problem with the trigger not resetting. It’ll reset if if I give the trigger a couple of good tugs and I can feel the hammer fall into place. Is the secondary seat spring tapered like an AR spring? I had a situation with a build wear the sear...

I did the trigger job off you tube as i have on many Minis but on this 189 Mini 30 i took off just a bit too much, now it shoots 2 round bursts..... Anyone know where to get trigger parts other than Ruger, I don't want to send the gun in ??? Thanks in advance.
