Look on the auction arms and try to pick up a used rifle in poor condition barrel wise, but with the 209 features. Many times you can get them for $75.00 . Then you have a spare trigger, spare sights, stock, etc..

I have three LK rifles and not one of them would I ever want to convert to the 209 system as the #11 system works so well. But I can understand why people wanted to. Good luck in your search. 80-85 grains of 2f powder and a 300 grain Hornady XTP is an excellent shooting load in all three of mine.
