If you have to grind on an AR safety to fit it, something is not spec. I suspect the trigger was worked on, simply because of the low pull weight and that there was no room to fit the factory safety.

It's exactly the symptom of an overtravel screw adjusting the trigger slack and removing it completely.

Thousands of enthusiasts have built AR's from parts kits and milspec is that all the parts drop in without any grinding or alteration. Hand fitting isn't necessary to produce a functional rifle. If anything, the factories just pull another trigger out of the bin and try it - if a low pull weight is even a factor on that lower.

Gritty, 8 pound triggers are military standard, and milspec is standard for most brands out there.

Something is NOT standard with the trigger in question here. A three to four pound trigger is for target range use and will be susceptible to accidental discharge in inexperienced hands.

I would not trust that rifle until an experienced AR gunsmith can check out what has been done and can explain it - and repair it.
