Ergo lower pk - ERGO AR-15 Enhanced Lower Parts Kit

Nice parts and very well packaged. Great lower kit for sure. One problem though. I spent a good half hour taking the grip on and off after I put the ambi selector in because it would not rotate properly. Come to find out that the LH side selector was on upside down as it came! I took the rh side off, slid it in over the detent and assembled 3 times to find out it wouldn't select properly. Took it out again and found the LH selector was on wrong as it came. Check it when you open it and make sure it's on the right way before trying to install.
