AR-15/10 Hammer. Mil-Spec. Made in the USA
So when you pull the trigger on your AR this little thing swings up and hits the firing pin causing the firing pin to strike the primer on the round thus causing the weapon to go PEW. Without it the weapon doesn't PEW. You want your weapon to PEW don't you?! This hammer replaces your worn or lost one so you can once again PEW.
