hop up know how???

[Junky]

I just purhcased a new stock replacement hop-up rubber for my KWA glock 19, Aswell as a tight-bore barrel.

I installed the new items and although i noticed a difference in velocity from the barrel the consistancy of my shots is horrible! Is this due to the new hop-up???? i am assuming they need to be "broken in" .... i have only put thru about 60 rounds since i replaced it. ???????

is this true or should i just get a new one again??

Try putting a bit of silly oil on a Q-tip and give the new rubber a wipe of it. Chances are your rubber is pretty sticky from being new, and having some oil on it is always a good plan. Also, put a wrap of electical tape about 2mm behind the O-ring on the inner barrel, that tends to bring out about a 75% increase in accuracy, much more than a tightbore will provide. KSC/KWA inner barrels tend to have almost 2mm in play in all directions which causes really bad accuracy, even at close range. Just putting the tape on will close your groupings by a LOT. Oh ya, heavy ammo (0.25g minimum, it sucks compared to higher weights, 0.20g is really bad!) is better in GBBs than light ammo for accuracy/range.

any chance the tightbore is a madbull? I have had some mixed luck with them.
