Got a used LE issued lower coming this week. It looks good from the pictures but I was wondering if you would replace anything just to be safe. I understand lowers don’t wear out much at all, but wanted some more knowledgeable opinions. Thanks

I would upgrade the trigger.  Not because the stock trigger is likely to be worn out, but because aftermarket triggers from Geissele or Larue are so much nicer.

It's super clean from the ad pics. And properly maintained by the LE armorer according to the seller.

I'd run it as is.

A wise man always keeps spares though.

It does look good in the pictures, probably will just run it

I'd make sure the buffer weight is what you want it to be for whatever upper is going on it.  If the trigger is heavy I'd drop some JP spring in, if its gritty I'd just replace it.  There's no "matter of course" things to replace though.

Buffer has a 3 on it. Putting a 14.5 on it

If you suspect a high round count, might be worth replacing the buffer spring.

I'd measure the action spring ("buffer" spring) and replace if too short and probably replace the disconnector spring just because I wouldn't know how old it is and $2 is not a lot of money.
