I have a first year Cynergy that has not cracked.
Estimate 10,000 target shells through it.
I do keep the screws tight.
Be advised that if you send one to Browning it will be returned with a heavy trigger. Why they insist on doing that to us is a mystery.
Not just everyone can do a trigger job on a Cynergy either, it's a difficult thing to work on.
They had a good idea there in the basic action design, but then they missed the boat with just about everything else.
This universal porting nonsense on everything they make now costs them sales.
