G&g Predator - rail misaligned.

[Eradicus]

Hi. Got a full metal a predator that'd be a pain to return to the store.

The front rail and also therefore the shaped block nearest the receiver (where you'd normally find a barrel nut) is out of line. If it were a normal barrel nut I'd say it'd been over tightened, so if you look at it from the barrel end it's offset a few degrees clockwise.

Can anyone tell me if this is a simple process to fix and if so give me some pointers?

It the rotational positioning of this block the rail slips over is variable and can be adjusted then I'll happily get my Allen wrenches out.

If this is a fault I cannot fix then I don't want to mess with the gun and I'll take the drive to the shop!

Any help much appreciated!

Thanks.
