Gun Rights T-Shirt I'm Good With Numbers 45 5.56 7.62 T-Shirt

When you're good with guns, you're good at a few other things, like aiming and knowing your guns. If you're a gun lover, gun owner, or Second Amendment supporter, this t-shirt is for you! It also makes a great birthday or holiday gift. In guns, especially firearms, the caliber or bore is the approximate inside diameter of the barrel, or the diameter (in hundredths or sometimes thousandths of an inch) of the projectile it fires. Know the numbers and statistics; we can protect our country.
