Then don't sweat it. Separate the upper and lower.
Bring just the upper to JoJos, its about a 40 minute ride to Southington.
While the upper is at JoJos, pin the lower.
You've got 90 days to make it legal, so no sense in not bringing it.
I'm assuming when you say pinning, you mean pinning the stock.

p.s. What brings you to east lyme. That was a big Pfizer town and everyone is moving OUT of EL as Pfizer continues to bleed jobs from CT. (And expands their presence in Cambridge) I'm sure you got a deal, especially if you bought one of the MANY high end houses left behind by Pfizer people.
I've lived in Essex, about 10 mi away for 21 years, let me know if you need any local info.
You want to join Niantic Sportsmen's, its actually in East Lyme. Decent place. Not as nice as the MA clubs and more money. But still worth it. If you need a sponsor for membership let me know.
Start digging for your NRA Basic Pistol certificate. You'll need it to get your CT resident pistol permit.
