Eurooptic.com?

I like the Euro Optic folks - solid bunch. I've met them at the NRA and SCI shows and have done lots of business with them.
They have high end stuff (barrels for my Blaser R8, Zeiss Victory scopes etc...) that I couldn't get anywhere else much less put my hands on them before buying.

I've bought a number of things from Europtic with no complaints whatsoever.

Excellent company to do business with.
