How accurate is it? Sub MOA?
How good are the parts?
How does it compart to a RRA Varmint Gun or DCM gun?

Joeken has them for $650, has anyone bought one from them?

The omega is made by Hesse.  The general consensus around these boards is to stay away from Hesse as durability of the products is hit or miss.  There reputation on their waranty and customer service also has been bad in the past.  I guess they left a bad taste in the mouths of quite a few members of this board.

However there have been a few people who have had good luck with Hesse rifles, but I have rarely seen anything written on the Omega Match rifle.  Joe Ken also adamantly states that he stands behind every product he sells, but I have not heard if this is true or not.
