I have another endorsement for them!
When I was mounting my FFIII on my 336 base, I stripped out one of the holes in the base.
Feeling really stupid, I emailed Burris, and they sent me a new base, and additional screws as well.
This company has the best customer service I have ever dealt with. It is very obvious they care about the people that use their products, and want them to be 100% satisfied!
Try getting that kinda help from other companies!
