Actually that could be a great idea for learning how to QS.  Never thought of it but it's simple and probably really effective.  Sure it's cheap but you've got to appreciate the inginuity.

I consider myself a pretty good sniper. In this game that means Im able to quickly scope in or 'drag scope' as well as conventional sniping. I will usually post decent scores (My best being 52 kills with the MSR in a game of KC) with a sniper rifle and always stay positive. Put it this way, I RARELY find another sniper that gives me a good game... Until the other day.

I usually check the in-game leaderboards and noticed that one 'restarter' had incredible stats, (17 KD). At this point I was very keen to play against him as curiosity got the best of me. He ended up on the other team and, low and behold I killed him twice before he pulled the plug and ended the game (he was host). I decided to call him out as a dashboarding booster. He replied with rage and insisted we do a 1v1 snipe only. I usually dont waste my time with these kinds of things but I gladly accepted as I knew I could hold my own against most players, especially with a sniper.

Let me just say, I have NEVER faced someone as good as this guy. We did a private match of free for all on Dome and he ended up picking me off before I could even get a chance. His accuracy that game was something ridiculous like 80% and he ended up beating me 30-13. I dont know if it was cause the radar was always on and he had just gotten that good at QS'ing, but he definitely was the best I have ever faced. I honestly dont think regular 2-3KD players stand a chance against this guy using a fully auto.

Whether there was something fishy going on, I honestly dont know. He still missed a couple of shots but over all he was ridiculously accurate and I hardly stood a chance as I would die as soon as he appeared on my screen.

For what its worth, check out his ELITE, his PSN is Kozmic-spartanx. I wish I knew what his real PSN was that he had been playing on all along before making the restarter account as it would have been easier to judge his innocence then, To answer your initial question, no I dont use the tape technique you have mentioned and have actually never heard of anyone who does.

Hes not a hacker he just played kill confirmed and got a really good score and stopped playing so his kd would be so high

@rlbl...

There was video of some young guys selling a thing that held a laser pointer in place dead center of your crosshairs.  It was here on the forums.

I took one of my kids jelly sticky things and took a tiny chunk of it and  stuck it dead center of my crosshairs after watching the video (I aint pointing a laser at my tv for hours on end) and I will be honest man it did absolutely nothing for snipers and very little for other guns.  The fire pattern is so random within the crosshairs that the red dot on my tv was worthless.  It fell off after a game or two and the vaccum ate it.   

It did help some with hip firing from high accuracy weapons while using steady aim as it essentially gives you a rds from the hip.

In private match you can hip fire into the concrete walls and the pattern is all over the place.

I think it has to be someghing else, possibly just really good players or some type of hack.

I wouldnt consider someone putting a small dot on their TV  a hack or considered modifying their tv's either.  I mean if thats the case people using kontrol freaks are modifying their controllers for an advantage as well.  I mean if putting a dot on your tv is the key to being good then shame on the rest of us for not doing it.....  All of us could do that which makes it fair IMO.

Sometimes that just how the game works. I played a S&D match on Seatown and final kill was a quickscope. The crosshair wasn't even close to the guys head, the bullet tracer clearly hit the ground, but the guy walked away with a headshot

Everyone in the lobby agreed that he shouldn't have gotten the kill. Quickscoping can have such horrible hit detection

I would say I'm pretty competent with a sniper rifle and I'm decent enough at quickscoping that when not hampered by the effects of lag compensation, I'll connect with a decent percentage of my shots.  It took a good few months to get there, with some terrible FFA performances, and a crushing of my W/L ratio and KDR, but nowadays I'm pretty much always positive by a decent margin. 

Anyway, when I was starting out trying to quickscope I went on youtube and searched for as many vids with tips and advice on quickscoping and also sniping in general, since it had never been one of my strong weapon classes.  I did come across a vid showing people putting makeshift red dots on the screen to improve their accuracy, so I thought, what the heck, I'll give it a try.  I actually found it to be more of a distraction than anything else and quickly decided it wasn't for me, because I was focusing more on the dot than the target. 

One of the things that I find difficult is centring the target before ADSing, particularly because I don't have great control and dexterity in my thumbs, so I find that I have much more success with dragscoping, which though quite fast and efficient in most situations, isn't as quick as a pop-shot.  I would say I'm average to above-average with pop-shots, as are most of the decent snipers I come across (the ones posting positive scores).  However, every once in a while I'll come across someone who seems to just be able to hit them almost every time and it's a tough proposition to deal with someone with such a high degree of control and accuracy on high sensitivity.  That isn't easy to do with such consistency.

That being said, when I see 2-3 guys being taken out by a sniper standing in the open I really have to question whether it's a case of the sniper being really good, or the other players just being really bad.  I've never had a situation where I've even had a 2 on 1 with a sniper in the open and he's been able to take both of us out unless one of us has foolishly stood right behind the other.  Even when you see those montage clips where the guy gets 4-5 man feeds, most of them have just been running forward like headless chickens, or looking the other way, Very rarely have I seen the sniper actually under fire.

Whether there are hacks, aimbots, sticky plasters on the tv it doesn't matter to me.  I am so fed up with quickscopers on small maps like Dome that everytime I get killed by one I simply backout, regardless of how good or bad I, or the team, may be doing at the time.  Part of me has  a little sympathy for the sniper, there are limited map opportunities in MW3 to snipe properly, but people who have no interest in sniping properly are the ones who bug me.  It has got to the point where I just dont want to be involved in their little games. 

I have my fingers crossed that Treyarch will come up with a solution to all this, such as sniper free lobbies, but I'm not holding my breath.  This issue and lag are two reasons I wont be buying BO2 until I know for sure what the game is like.  If I had known MW3 would have as many quickscopers as there are I would never have bought it, but it's too late now.
