By this, I mean that if a sysadmin has asked you to provision rack 14A, Switch-2, interface Gi3/5, make sure that’s the port they really mean. Don’t take their word for it that the port is available. If the guy who ran the cable made a mistake (even if that guy is you), you might be re-provisioning a production port and causing an outage.
With that said this trigger kit shows that high price mean blaaaahhhh, it does the job and does it well. I also got the single stage trigger kit and compared them both, with the 2 stage you definitely get that more control pull if your trying to be very precise and controlled. I completed two builds both have the 2 stage kit .223 wylde and .308.
