I'm just replying to just the first part of your question (Are there any shooting gadets that you thought were stupid...).
Well yes, now that you mention it, I think hanging all kinds of crap off of AR-15 is ridiculous. Maybe it's just me or maybe I'm just an old fart but I hate the way a lot of people think that they have to hang FOUR Picatinny rails on every AR-15 and then see how many gimmicks they can hang on it! I think it's obscene the way that they try hang 10 pounds of crap off of a 6 1/2 pound rifle! If I need a bipod, the original cloths-pin type clip-on bipod works wonderfully and is completely out of my way and doesn't affect my POI when I'm not using it. And I don't need a flashlight on my AR-15, Thank You! I'm not planning on going into a cave to hunt bats! And having a flashlight on your gun is about the best way that I can think of to target yourself to the bad guys! AND don't get me started about people that remove the original carry handle then turn around put on a Picatinny rail so they can mount another carry handle! I could go on and on but I'm sure you get the idea. I like the original SP-1, and with the possible except of the more easily adjusted A2 sites, I don't want anything else added to it.
Sorry but YOU asked.
Interesting you point out that you aren't answering his actual question, but then allege that's what he asked. but then again, the rest of that made as much sense.
This whole statement made my head hurt. Here goes...
So you don't want people to hang 10 pounds off a 6.5 lb rifle, should they only do that on 12 lb rifles?
It's amazing you reference your clothespin bipod not affecting your point of aim when you aren't using it, but completely overlook that it does when you ARE using it. Those picatinny rails that you quake in fear of are likely free floated, which will ACTUALLY keep your POI in place.
I guess you were trying to be amusing, implying that lights on rifles are for caving, but personally I would like to be able to see what I am preparing to shoot, as opposed to firing blindly, which seems to be your intent. Or maybe you're just hoping that anything that happens will only happen in the middle of a sunny day, outside. Either way, you sound like a danger to yourself and/or someone around you.
And yes, it might be you and you might be an old fart.
I am not a fan of (even pressure activated) flashlights on AR-15's or assault rifles. I know I'll catch flack for it, but "FOR ME" I just can't stand it. Its weights the gun down and seems pointless when I can just get a night scope or something.
Welcome to THR.
I don't follow your logic. A light will weigh the gun down, but a "night scope" won't? Pointless? How is illuminating what you are preparing to destroy, as well as some periphery pointless? I suspect you havent used night vision before, so let me help you experience it. Go get a paper towel tube and then look down it and through a window screen into a room that is dimly lit with a green lightbulb. Or, you can bathe your target in a nice white light and be able to see other things around you.
