Sig Arms rifle parts & accessories?

[bellero]

Where does one shop for Swiss Arms parts and accessories? I just got myself a Black Special and I'm looking at getting myself a few accessories such as a cheek rest and maybe more. Also interested in getting the Swiss Arms extendable bipod.

Thanks

CSC in Calgary has a display case full of parts.
