My son-in-law hunts and shoots with me a lot. He always looks like a Navy Seal when we go out. Even his Ruger 10/22 rifle looks tactical. It's almost embarassing to take him along. Trust me, all that tactical equip and looks don't seem to bring him any mor results, but he sure looks cool.
I don't see a problem. You see the same thing in the automotive realm. People who came of age thinking big-block Chevelles with Edelbrock intakes and Holley carbs were IT, make fun of the guy driving a slammed Civic with 20" wheels, wings, levitation lights, an aftermarket turbo kit, and video screens on the seatbacks. So what? Different strokes for different folks.
I personally think firearms covered with engraving are ridiculous, so I wouldn't own one. But if someone thinks that's a work of art and wants to own one, more power to him. Cowboy-style guns don't appeal to me either, and neither do revolvers. But there plenty of cowboy action shooters and revolver enthusiasts here. Good for them.
I think putting a bipod on an M4gery is rather silly, BUT if you like to shoot from the bench, what's the difference between a bipod and a benchrest w/sandbags? Not a lot.
Lights and red dots ARE practical accessories, and I am currently in the market for a holographic sight for my SAR-1. Not because I don't know how to use the irons, but because a holosight is faster in good lighting, not cheekweld-dependent, WAY faster in less-than-ideal lighting, and NEAT.
