I have one. I am pretty happy with it. We have some clones on the German marked and I chose the XR41 as the best one to get over here.
The XR41 is basically a Greek manufactured G3 (EBO, HK-licensed), modified for the German civilian market. It has a hooked semi trigger housing, cold hammered bull barrel (under the wide handguard), mag.-flapper and flashider.
It´s a solid rifle and it shoots like hell. If You can get one - take it.
Take a look at the German importer, Schumacher, who just says that they´ll be sold out very soon, but will come again in march 08. Sabre Defense should have made a contract for another thousand with EBO (possibly along with a deal for Cannada).
If You are able to get civilian rifles from the German marked, start counting money: German Federal Criminal Police Office (Bundeskriminalamt, BKA) has just proven the civil-416 and 417 (yes, HK German made) to be legal for civilians... So watch out for some "MR223"s and MR308"s, next year!
