I see you're in the Merrimack Valley, couldn't you just have it held at the Wilmington, Chelmsford, or Billerica FedEx?
My first CMP delivery was in 2000 while my house was undergoing an addition/renovations. I wasn't home with FedEx came but the carpenters (all hunters) knew what was in the box and told me when I got home. FedEx returned the next day and I'm pretty sure I had to sign for it.
Depots are open late. IIRC FedEx depots are open until 7PM. I'll assume UPS is similar, so many folks can hit them after work.
Late would be good, give me time to get over there, or I could leave a little early. That route means I'd have to delay gratification though .
Based on majspud's post in the other thread, it looks like they don't need much more than an inspection and lubrication. If that's the case, if I arrived and I was home then I could make it to the range same day, all things being equal.
If I'm not able to get my hands on one before they stop orders again, I will truly feel cursed.
