Ok, so this is pretty much inside baseball but I thought I'd post this for the Missus and Young Son who are both pony fans and YS is also a Brony. If you don't know don't bother asking.
When someone has an AR-15 named after them, they gotta be one tough pony!
For those not familiar with the hardware in this image, shown below is an AR-15 receiver mock up with appropriate MLP oriented engraving. Don't even think Brony's aren't manly or they may shoot your apples off!
