This is my first build, so please be gentle.

After assembling trigger/hammer/disconnector, function check fails.

Hammer falls forward when trigger is pulled
Hammer jams on the disconnector (will not cock) if trigger is held back, trigger must come forward 1/8" in order for hammer to get past the disconnector and cock.


Is this a thing?   If I had to fix it right now, knowing what I know now, which is almost nothing, I would file down the rear/lower tab on the disconnector, aft of the disconnector spring a few hundredths.

parts out of spec?  did I make an error?  it seems straight forward.

My off-the-shelf ar15 doesn't have this issue.

Safety is not yet installed - does that keep the trigger forward enough when the user is pulling back?

Standard parts need the safety installed to function check. The safety limits the trigger travel distance even in the fire position. Sounds like you may have already figured it out though.

Confirmed - thanks.  my "off the internet" instructions called for a function check prior to safety installation.

All together, works great.

thanks again,
