Concur with M.D. on the weapons. While New England gunsmiths knew how to make rifles, consumer demand in the area was predominantly for fowlers and so it was with fowlers (or smoothbore muskets) that many New Englanders rallied to the colors (of their choice).
The one documented rifle was unusual as it was fitted with a telescope sight. The rifle was owned by portrait artist turned militiaman Charles Wilson Peale (yep, the famous painter). Peale had a telescope fitted by instrument maker David Rittenhouse. However, while he managed to hit a piece of paper at 100 yards, nothing shows that he ever attempted to use it in combat.
