A Brooklyn couple was arrested yesterday for keeping a small arsenal in their home, cops said.

Harvey Rodriguez and Colette Barotti were under investigation for allegedly hawking stolen jewelry on eBay — but when investigators arrived at their Mill Basin house at 6:30 a.m. with a search warrant for the baubles, they uncovered a cache fit for an invading army, cops said.

There were at least 10 weapons in the Montana Place home, including an Uzi and an AK-47, as well as several handguns, cops said.

They were chargedwith criminal possession of weapons.
