Airsoft Canada - View Single Post - Loss of accuracy after tight bore upgrade... why???

ao_tenshi · April 26th, 2013, 20:04

Hello all,

I would like to get some advice from the community about the possible reasons why an inner barrel upgrade would cause a loss of accuracy. This is my first attempt at upgrading an aeg...

I have a stock KWA M4, which was shooting very accurately (1/2" groupings). I've recently upgraded the inner barrel to a 509mm madbull 6.03mm tight bore (stock was 395mm). No other mod except a suppressor extension to accommodate the longer inner barrel.

Now with this upgrade, Im getting extremely inconsistent shots and groupings as bad as 3-5"... any suggestions on the cause of this and how to rectify this?

Thanks in advance!!!
