UPDATE: Clownbow, just wanted to let you know that what Uturn posted was correct. Brownells does have them in stock, arrived this afternoon. Installed in the lower, put the halves back together & it fits in there like a charm. Cycled the bolt a couple of times with an empty mag, and it catches like it's supposed to. I banged the rifle a bit to see if it would release (had read that it didn't like to hold the bolt in another thread), bolt stayed locked back. Hit the lever to release and all worked well.
I'm not sure how many of them Brownells has but you may want to order one up quick if you really want one. A little pricey, but if it's the one thing that works, I'll pay. $60.94 to the door. Was a little tweaked that there wasn't at least a sticker for the reloading bench, but oh well.
Good luck.
