In case you've been thinking about doing a 209 FPJ or a 209 bare primer conversion on your knight bolt action Sportsman warehouse has them on sale for 64.97 with free shipping. Direct from knight they are about 3 times that much. They have the conversions for the Mountaineer and the Ultra lite. But if you have a newer disc extreme the bolt will fit but not the breech plug. I just bought the mountaineer bare primer conversion for my disc extreme and the bolt fits perfectly. It's a fancy bolt , jeweled and the bolt handle is knurled. The picture on Sportsman's warehouse doesn't show the jeweling or knurling but mine was. I've been using the FPJ bolt with the lehigh primer adapter but for this price it gave me a spare bolt. I tried the internals out of both my western bolt and my FPJ bolt in this new one and they both fit perfectly. So the only other parts you would need for your disc extreme would be the Lehigh bare primer breech plug and the vent liners. scroll down the page on the link provided.
