The National Rifle Association released a new app on Sunday that includes a gun range equipped with coffin-shaped targets, and the option for players to simulate using a military-grade sniper rifle.

According to Think Progress, "NRA: Practice Range" is billed as a "network of news, laws, facts, knowledge, safety tips, educational materials and online resource" for the organization.

The app includes what it calls "9 true to life firearms," and allows players to download an MK-11 sniper rifle setting for 99 cents. The rifle can shoot 750 rounds per minute.

"Practice Range" was released almost a month after the mass shooting at Sandy Hook Elementary in Connecticut, which gun advocates have insisted should be blamed on violent video games; Rep. Marsha Blackburn (R-TN) said in a CNN interview she was "astounded" by scenes from the "Call of Duty" game series.

However, as Think Progress also reported, some gun manufacturers have partnered with video game creators, granting them permission to use real gun models as a mean to market their firearms.
