(C&P from Kirby's FAQ)
How long should I expect it to take for a rifle to be shipped from APS?
Currently, I am telling my customers 12-15 months from time of deposit receipt. This is a best guess estimate in good faith. At the end of 2009, I was 26 months on full custom orders. At the end of 2010 I was at around 20 months. This is also dependant on component makers getting me the parts in a timely manor and those parts meeting my requirements for quality which does not always happen. If a stock or barrel or receiver must be returned for replacement because it does not meet my standard to build on, it will take more time but this is relatively rare but it does happen.
Good luck!
