This lower came with the quality you expect from Jmac. the “Auto” selection isn’t just for show, as the internal is cut to accept the 3rd pin components, should you SOT & drill it.

This product is high quality, and was machined flawlessly. 10/10 would recommend, and 100% chance I will continue to use JMAC products.
