This is a great lower parts! Very high quality for the price, unlike other cheapo parts kits you might find at your local gun store.
Note: This kit does NOT include the Fire Control Group (No Trigger, Hammer, Retaining Pins, or associated springs).
We highly recommend using a drop in trigger anyways.
