KSC G19 shooting to the left
My ksc g19 has been shooting very accurately up until last week. After installing some upgrades (new hop-up rubber, metal slide/barrel, high flow valve on mag, and an upgraded valve knocker/hammer spring) the bb's were swerving upwards right after leaving the barrel. So I turned the hop-up dial to reduce spin. My bb's now fly fairly parrallel to the ground, but the dial had to be turned all the way to the right, which is supposed to mean "no hopup". Even though it seems strange, i wouldn't really mind this if my bb's were firing straight. They now swerve to the left quite severely.
I was thinking that there is either something wrong with my hop-up unit or that my barrel is slightly bent for some reason or a combination of both? The barrel has been recently cleaned and everything lubed up nicely. Any suggestions? |

Remove the barrel assembly again and check that the hopup rubber is even in the gap the barrel has in it (hopefully you know what i mean). If it appears to be centered in the gap and the hop rubber looks even, simply try rotating the barrel in the chamber just a couple degrees this can often effect the bb's flight path.

OK i took it apart again and re-aligned the barrel and hopup rubber. When i looked through the hopup rubber it looked like the bump where the hopup bearing is located was off to the left a little. Now (after taking it apart and re-aligning) it looks like its parallel to the loading ramp and looks a lot better.
Its a little late to test it out, but ill be sure to post up my results tomorrow. |

Heavier BBs will make it more accurate too, I've used all the way up to 0.43g BBs (I mostly use 0.28g now unless indoors, then I go with 0.25g) to compensate for random shots. Something else for you to do is to wrap tape around the inner barrel just behind the O-ring, and build it up to the point there your inner barrel doesn't wiggle around while in battery. KSC Glocks have bad barrel wobble, and doing this fix (will take some adding and subtracting pieices of tape to get it to fit right) will give you a huge boost in accuracy. These are more tips that I felt like sharing as opposed to fixes for your issue.
