Guys,
I have a lower that I milled identically along with two others using 5D router jig. One lower will not allow the trigger to function properly. At first I tried drop in trigger and it would not function. I then installed a known working mil-spec trigger from another lower and it seems like the hammer can be set at "half cock" and will work pulling the trigger but when the bolt cycles the hammer is pushed further down and is fully cocked but will not fire by pulling the trigger.
Before I start filing, stoning or removing more metal can anyone provide any insight into this? I am assuming this is a common problem and knowing what to address initially may help me save some time.
Thanks.
