Bullet key chains using deactivated rounds of the caliber of your choice. As with other items in this shop, we can make these from your own bullet if you prefer (must send a live round to be able to make these or a deactivated one with the bullet still with it). FREE SHIPPING on orders of 4+ 50 BMG is MASSIVE. Look at the picture of it on the hand for comparison.4.6×30 and 5.7×28 are quite smallIf I don’t have the caliber you want, message me and it is likely that I can get you it. All rounds have been modified so they cannot be used for their original purpose again.
