I have a new Jewell HVR top safety trigger for a rem 700 I just installed in my EDM Arms XM408 and am having a big problem. When function testing the trigger it works fine without the safety engaged, but when the safety is on and I try to pull the trigger and then switch the safety off, the gun fires. It releases the firing pin as the the safety lever is moved off. Is there an adjustment problem in the trigger or what?!
