So I've had some "no primer strikes" with my Velocity trigger and CMMG upper (these are not light primer strikes; there is no evidence of the firing pin touching the primer).  In looking at the trigger mechanism I know if I manually cock the the trigger normally the hammer and sear are not engaged.  During pre-travel (take-up) the surfaces sear and hammer surfaces engage and with a bit more trigger movement the hammer falls.

If I manually cock the trigger too far the hammer comes to rest on the sear component forward of the engagement surface and the trigger is effectively locked up.  I don't know if this is the cause of my issue and I'm guessing the ramp on the bolt is designed to cock the hammer "just the right amount" to avoid the "over-cocking" phenomenon.  Is it possible there is an incompatibility between the CMMG bolt and Velocity trigger design?  The Velocity trigger is the AR variant as appropriate for the CMMG.  Any thoughts.

The next time this happens I'm going to put the gun on safe, pull the pins and take a look at the trigger assembly.
