So I recently acquired a Spikes tactical rifle. Owner told me the whole rifle is spikes, EXCEPT lower parts kit was CMMG. Anyway it shot ok but noticed the trigger pins were walking out. Upon further inspection th hammer spring was upside down. Fixed it and re-installed both hammer and trigger pin so the the double grooves are on both sides. This was my first time doing anything on an AR lower. I did notice it made the trigger quite a bit heavier after doing this.
Anyways I perform a function check, all is well, HOWEVER, 1/5 times if i stage the trigger to the "wall" before break it will fail to reset back to normal position.
It has a badass selector that i re installed. i notice while its "stuck" if i manipulate the safety it can sometimes return to normal position, however with safety removed completely the trigger still sticks 30% of the time, especially after a "full trigger pull" and completed reset.
This is bugging the hell out of me and am wondering if i screwed up, or is it shit trigger components... Any help would be much appreciated I'm considering just swapping out entire trigger group since I cannot verify all was initially installed well.
