The Blaser Tactical 2, LRS2, LRS1 and CISM rifles utilize a common accessory system known as UIT or the Anschutz Rail.
I purchased a small amount of 1913 rail to attach an Atlas Bipod to mine. But with all of the available UIT attachments options available, the world is your oyster.
If you are having problems finding UIT accessories for sale online, try searching for companies based in Europe. Either directly or through Amazon & eBay. They will have more UIT / Anschutz components than you can shake a stick at.
Hope this helps.
