All too many works of art have been digraced with slotted recoil pads and white line spacers. Would those same defilers draw a mustache on the Mona Lisa? Ignorance, illiteracy, and narrow mindedness have impeded the progress of civilization and stained our collective sense of aesthetics since man first drew breath.
"What? Who's Shelhamer?" (ignorance, born of firearm illiteracy) "I'm gonna put this recoil pad on it anyways. It's my gun and I'll do with it as I darn please." (narrowmindedness)
Sigh.
