I recently purchased a McMillan Adjustable Cheek Pad for my DMR project. They are really curteous and helpful. Talked with a Tech about the installation as they don't come with installation instructions, and he was very helpful and answered whatever questions I had and I didn't feel rushed at all. Well after the installation I found that there was a problem with one of the screws. It was a smaller diameter than the other. I called them and there was no problem. They said they'd ship me out 2 new screws and they came in 2 days later. Ya can't beat that. I'm impressed. I would not hesitate doing business with them in the future.
