Kevin and Rosemarie Wyatt of Medford, Oregon www.wyattsoutdoor.com have developed a phenomenal drop box magazine setup that I used recently in an intensive four day long range rifle training course at Thunder Ranch. Good stuff, and worked flawlessly on my Remington 700. For our customers in the Pacific Northwest, the Wyatt’s know their gunwork, and are all around nice folk as well. Check them out when you need custom gunsmithing-I think you’ll like them.
