Just got my CPM, One problem thats bothering me. It appears that my iron sights are way off (they don't line up). The bbs shoot to the left about three inches off from the front sight, consistently, and the hop-up adjusts fine. Im pretty sure the barrel is not warped or anything, but my front sight definitely is crooked. I understand the front sight wobbles and may misalign, but I am unable to adjust it far enough back to the left (it stops). I am trying to remedy this, but my flash hider doesn't come off with ease. I heard the newer CPMs have the spring operated pin glued to into position, hence me not being able to disengage (it does look like there is glue on it). Anyone have any techniques of loosening super glue? I heard about heating it but thats all I've heard.
On the plus side, the gun shoots past my standards of an AEG. I don't use AEGs, this is actually my first for the most part, compared to my friend's G36s and P90s this shoots much straighter and harder it appears. Also, the hop up effectively works!
