I have one just like you described....well, I think, mine is heavy, stainless, 26". I had to work on the forearm also.
The hanger system can be found used on ebay and Gunbroker.com alone or with a forearm occas. you might want to look there. Bullberry has lots of encore goodies. You can find them on the web, you might also want to check out eabco.com (E. Aurthur Brown and Co). . Mine did about 2moa oob. It is now shooting about 3/4" groups of 5 shots. My only complaint is it's on the heavy side.

Good Luck and let us know how it shoots
