*and wouldn't that be 53 grain Vmax, not 54 ?
I had an AR15 with a Geissele S3G, a RRA National Match 2-stage, and a couple Mil-spec triggers that were stoned/polished to a cleaner break than stock.
I've shot an AR with a Timney, and KAC SR-15 with their 2-stage Match trigger also.
The
VELOCITY 3lb SINGLE STAGE STRAIGHT TRIGGER W/ FINGER STOP was by far the best AR trigger I've ever had the pleasure of pulling...
It was on the BCL-102 I had.
