If you need a first-rate gunsmith for a service rifle, Sinclair International has compiled its own list of smiths including highly respected names. For service rifles (including AR types), Sinclair recommends the following:

To Sinclair’s list we would definitely add John Holliger of White Oak Precision. John built the upper for the Smith & Wesson M&P AR with which Carl Bernosky won the Camp Perry High Power Championship in 2007. This marked the first time an AR-style semi-auto has won that event. John also builds many outstanding components for AR-style rifles, including windage-adjustable front sight bases, and the White Oak Precision Adjustable Buttstock (right).
