Good Quality
This lower shipped quickly, and everything was as advertised. This is my first Ambi lower, and I love it. There were no QC issues. If I find anything wrong I will update my review.

Love it overall
Overall I really like this lower but it does have some blemish like in the front of the magwell where the front pivot pin there is a straight line that seems to be during the machining process. I thought it was a crack at first. Otherwise the lower is wonderful. I also got a buffer that is unmarked so I'm assuming it's not at least a H buffer and just a carbine buffer weight. I paired it with a colt upper and acog and it feels so great. The ambi controls are amazing even for a right hand person since you can manipulate and release the bolt with your right index finger. Overall it changes the feel of a classic rifle and certainly makes any current build you have even better. Overall I recommend.
