5.56x45mm NATO Caliber T-Shirt
Grey:Black:Description: Whether you put in time for our country with the M16 rifle, M4 carbine, or M249 SAW, own an AR-15, enjoy plinking with a Ruger Mini-14, or like to push long distances with a Remington 700, this shirt is for you. If you're not familiar, the 5.56x45mm NATO cartridge is the miliary higher pressure metric child of the ubiquitous .223 Remington cartridge. If someone "not in the know" asks you why there's a repeating multiplication question dealing with measurements on your shirt, just make up something clever then tell the the answer is 250.2mm. Another great design subtle enough to wear anywhere. Details:
