The nation's gun manufacturers use "disturbing sales tactics" to sell assault weapons to civilians while failing to track deaths or injuries that result from the use of their products, according to a report issued in late July by the House Oversight Committee.

Driving the news: In late May, the committee opened an investigation into five gun manufacturers in the wake of deadly mass shootings in Uvalde, Texas and Buffalo, New York.

The big picture: Gun manufacturers have reaped more than $1 billion from sales of AR-15-style firearms in the last decade, the report stated.

What they're saying: "How much are the lives of America’s children, teachers, parents, and families worth to gun manufacturers?" committee chair Rep. Carolyn Maloney (D-N.Y.) said in a press release.

The big picture: In opening its investigation, the committee requested information regarding the manufacturing, sale and marketing of semi-automatic rifles from the five gun makers: Daniel Defense, Bushmaster, Sig Sauer, Smith &Wesson Brands and Sturm, Ruger & Company.
