Apparently I am losing the last bit of sanity I had, thought I had placed the order even had set up an account, but must not have actually placed the order. No charges to my credit card account and no history of the order with Numrich after all.
Just ordered a trigger extension part # 280780A and a "replacement" striker & lifter assembly (transfer bar) part # 1139220B which were both shown as being in stock. Sure do wish I had noticed the "failure to place order" sooner because I have been looking for them to get here for a week. Was hoping to get them installed ahead of our 2nd primitive weapons season which starts this Sat. Guess it is time to primer up a batch of cases and practice my "handi-rifle" trigger pull technique.
