Any time I need anything it is here when I need it without question. I have tried other suppliers and ship dates are not honored sometimes it can take two weeks for item in their stock!! Thanks for being consistent and prompt.

After an extensive look for parts, Ramona Real of Military Fasteners was the one that could help in finding what I needed and provide the necessary paperwork to go with it. Shipping on time and packing perfect. Good people to work with and highly recommended A+++++
