You can use any standard lower parts kit. The only one you can not use is the one with colt large pins,
When you find a LPK, don't worry which trigger is in it. They can be a little hard to find at the moment.

The difference between a 2 staqge trigger and a standard trigger in simple terms is,
A two stage trigger has a long take up to sear engagement where there is a noticeable stop, then a light release that is useally very smooth, crisp and short.
A single stage trigger has almost no take up and a heavier trigger release.
On a stock AR trigger it is useally fairly heavy and gritty.
This is only a short basic description. There are a lot of single stage triggers that are very good.

Hope this helps.
