As an engineer being practical is something more than just design philosophy. I don't buy stuff just because it's cool. Each tool in my workshop has a definite purpose and gets used. I don't buy them just to have and to hold them. When it comes to building my tactical 870 shotgun everything has a purpose. I bought the sidesaddle shell carrier with picatinny rail because looked at the ergonomics of reloading during a course of fire and I wanted the reloads on the receiver not on the stock. I've allways looked at the various heat shields for shotguns and quietly chuckled.
Until I burnt my hand on the barrel of of my 870 on Friday. After a dozen rounds downrange the damn barrell gets HOT! Coolness factor may be a good thing especially in a heat shield.
