Heard of this for sixguns. I pull them apart and smooth everything, change springs.
For AR, I have just bought acceptable triggers, and accepted what they gave.
Great triggers are nice, for most, any halfway decent triggef will suffice.
If I ever decide on a super acvurate AR, then Gieselle would get my money.
The thing is, you don't really know how accurate your AR is until you put a good trigger in it.
