Go to the Knight Web site if you want one. They sell for around that cost. Then check some of the other stores to see what their prices are.

I am wondering why you think you need a 209 conversion for a MK85. Granted they used a #11 cap, but they were one of the most consistent ignition rifles ever. As long as you used loose powder (other then Black Horn 209 and some of the other new ones). Those things just went off.

I have a Wolverine LK-II with the same ignition system as you. I personally like the ignition system.
