What is the stupidest firearm accessory you have ever purchased and why?

[Troutburger]

When did you buy it? The M1 Carbine stock

Got last spring.

Got last spring.

 Oh OK, I was just wondering if you could have posted a warning before I bought mine, but I was first. lol

 

When I saw the kit (And only $75 extra for the sights), somehow I ended up here http://www.shootingtimes.com/2011/06/09/22-rimfire-garand-parts-list/ and several other similar places and thought about the 10/22 Garand after the M1 Carbine. But after my M1 Carbine fiasco, decided against the Garand 10/22.

If you've never experienced the "tunnel vision" that happens during actual self-defense scenarios then you really will not grasp exactly how useful laser sights are on a defensive weapon, especially when there are multiple hostiles.

They might seem "gimmicky" for recreational range use, but trust me when I say that there is no better weapon sight when looking through that adrenaline induced tunnel.

If you are going to get a laser get a green one. Red is useless in daylight and even though it works in nighttime a green is amazing in comparison. I used my green laser to point out stars to my niece.

a magnifier for my red dot.. it was on my gun for about a minute...

Happy to say that I haven't fallen for any useless add on for my pistols. I was contemplating a laser at one point but one day at the range someone next to me had one. I quickly realized that it would be more of a distraction for me and they never crossed my mind again! If I knew who that guy was I would thank him!

Beat me to it.

Considering I can't shoot for crap anyway, most of them are pretty dumb actually.

Vertical foregrip I guess.

Vertical foregrip for an AR comes to my mind first as well.

Magpul BAD lever.

Going to go with the gear for my kel tec plr16.  The gun is awesome.  In a fit of not knowing what I was doing at the time, I bought the forend which added a significant amount of weight, and a pistol scope.  The forend I took back off once I realized that putting a grip/bipod on it was not legal, making that purchase useless.   The pistol scope is nice but not what I expected, and it will likely be canned for a red dot someday.   I would have been better off just keeping it as-is from the factory, after all was said and done.
