A recent study published in the Proceedings of the National Academy of Sciences reveals that across all political and social groups in the United States, there is a strong preference against living near AR-15 rifle owners and neighbors who store guns outside of locked safes. This surprising consensus suggests that when it comes to immediate living environments, Americans’ views on gun control may be less divided than the polarized national debate suggests.
The research was conducted against a backdrop of increasing gun violence and polarization on gun policy in the United States. The United States has over 350 million civilian firearms and gun-related incidents, including accidents and mass shootings, have become a leading cause of death in the country. Despite political divides, the new study aimed to explore whether there’s common ground among Americans in their immediate living environments, focusing on neighborhood preferences related to gun ownership and storage.
I’m assuming the magazine size. Which is generally why magazine size is the common way to enforce which rifles are considered problematic for home ownership.
There’s nothing physically preventing anyone from putting a readily available 30+ round magazine into a Mini 14.
It even says “same capacity” right there in the picture. Although to be fair, the Mini 14 in that picture either has a flush fit low capacity magazine installed in it or is unloaded.
