Accuracy problem
 

Hey, i just bought a BNIB CYMA Aks-74u From Bob the angry potato. He said that is comes stock with a tight bore, metal bushings, and I believe him, but when I tested it, i couldn't even hit the same spot on a newspaper from 30 ft.
I have heard that the aimers are off with these, but im not convinced. Could there be anything else that is affecting my gun? Any solutions to get better accuracy. And also, i was using .20 gram BB's in a windless environment.

Clean your barrel, there might be some leftover crap from manufacturing (Well known for dboy's guns to have shit tons of grease in their barrels, I don't know about CYMA though, well worth a try, and a good habit to have.)

If that doesn't fix your problem, it might be your hopup, consider getting a new piece of rubber.

Did that, probably should have mentioned that. :D

buddy, airsoft guns are not real guns. They won't hit the exact same spot everytime.

And AKs have crude sights, they are hard to have consistent shots with.

Good to know, this is my first AEG after all, i guess i was just expecting it to be a lot more accurate, especially if it has a tight bore.

could be BBs...or your aim!....lol

Haha, could be, but I don't think so ;) Also conscript, it was 30ft, the hop-up was unadjusted, and i don't think that would affect it, as it was 30 ft. Never know though.

the best grouping I got at 30 feet with an AEG indoors was 0.6 inch. at 40 feet, it will become 1 inch.

Yea, if your spread is like ~1 inch with the gun anchored, I wouldn't worry too much about it.

Definatly worse than that :o I was thinking maybe a scope mount, and a simple RDS would correct the sight problem, if there is one. Any suggestions? Also would anyone happen to know the approximate FPS with .28 gram BB's, when its stock 490 with .12g? I did the pop-can test with my .20, and it went through both sides, so I'm estimating 360-380? But i would like to use .28;s, so i would appreciate any help.

Have you adjusted your hop up (as in, made sure it's on)?

Often you will see a performance decrease if you turn your hop up off.

+1 to the bb's. I changed weight and brand and went from 55% to 85% accuracy. (accuracy meaning number of bb's hitting a small target.)

Also make sure you hop-up bucking rubber is sitting nice in the chamber and on the barrel.

Or you could just have a lemon....:D

To tell you the truth, I'm not sure, i havent gotten a chance to test it out longe range, as i live in a rural area, but if you have one, or have seen one, the pull able tab which im assuming is the hop-up(im a new guy), the tab is all the way to the right.

Accuracy has a LOT more variables than just the barrel, it's affected by every part in your gun that comes in contact with the air that moves that BB, the piston head, cylinder, cylinder head, air nozzle, hopup rubber (very important one), and of course the fact that CYMA AK's aren't very good at anything to begin with...
For starters switch to .25s, and buy a 5$ upgrade hopup rubber. Make sure that barrel was installed properly as well.

Take your flashhider off and look down the barrel (observe usual safety protocols). Is the inner barrel centered within the outer barrel? Does the inner barrel have a lot of room to move/wobble inside the outer barrel? If so, wrap some tape around the inner barrel, until it no longer wobbles inside the outer barrel.
