How can i due with this problem?

Well if your mount is from G&P, then it's probably the RIS, what brand of receiver or brand of aeg is it? I had a problem with my JG where the RIS was a tad too wide and had all sorts of mounting problems.

its most likely the gun, i bet its TM.

which means his front section of the outer barrel is off center.

i think its already mentioned but losen the screws from the chamber block and twist the front end back to center, use the rear sight as a reference point.

peace.

The m4 is from ICS
both of them are new.

Try that. Your front sight might just be off center from shipping/factory etc.

I have already checked. it is not the front sight proplem. I took off the redpoint and check the G&P .I think is the G&P problem
