Connecticut’s entire congressional delegation has proposed legislation that would designate the site of an historic firearms manufacturer as a national park.

The move comes even as the same Democratic members are fighting for tougher gun control laws in the wake of last December’s mass shooting at an elementary school in Newtown, Conn.

Rep. John Larson (D-Conn.) and Sen. Richard Blumenthal (D-Conn.) proposed the Coltsville National Historical Park Act, which would have the Secretary of the Interior administer the site of Samuel Colt’s Firearms Manufacturing Company. The site in Hartford, Conn., which Colt founded in 1855, is already a national historic landmark.
