Federal authorities on Tuesday seized guns, silencers and more from a federal firearms licensee in Indianapolis after a months-long investigation revealed the west-side gun shop violated federal laws, the U.S. Department of Justice announced Wednesday.

The Bureau of Alcohol, Tobacco, Firearms and Explosives found evidence that G2 Sport Products, 8255 Indy Court, knowingly transferred handguns to an out-of-state resident, made false entries in records, failed to report multiple handgun sales and knowingly transferred firearms to a prohibited person, U.S. Attorney Josh Minkler said in a press release.

The store's owners agreed to the seizure of about 390 silencers, receivers and firearms — including rifles, shotguns and handguns — Minkler said. The items seized have a total estimated value of $224,000.

The store also agreed to an "enhanced surrender" of its federal license. That means the store's owners cannot reapply for the license and cannot deal firearms anymore, Minkler said.

The seizure comes after Scott Genung, who said he was responsible for much of G2 Sport Products' store operations, was indicted on a charge of being a prohibited person in possession of a firearm, Minkler said. Undercover law enforcement bought several firearms at the store from Genung, who is a convicted felon, Minkler said. Genung carried a firearm during those transactions, he said.

Genung was convicted in Hamilton County in 2002 of conspiring to deal a schedule I, II or III controlled substance, according to online court records. If he is convicted of possessing a firearm as a convicted felon, Genung could face a maximum of 10 years in prison and a $250,000 fine, Minkler said.

Genung, 43, is the president of ROMAR Concepts LLC, and worked customer service for G2 Sport Products, according to court records. The businesses are located in the same building.
