The 41,040-square-foot property at 61 Arrow Road sold last month.
The buyer was Dajana Delmic, who, along with her husband Miodrag Delmic, owns Cheshire-based online bulk ammunition retailer Target Sports USA.
The Delimics have been on a Greater Hartford buying spree in recent months and many of their purchases involved investment properties unrelated to their core business.
In late April Miodrag Delmic purchased the Crossroads Plaza neighborhood center in Cromwell for $5.1 million and in November they bought the former Wethersfield headquarters of the now defunct healthcare consultancy Qualidigm (936 Silas Deane Highway) for $2.2 million, among other recent deals.
The seller of the 61 Arrow Road Wethersfield property was Russell Road Properties LLC.
