[ARCHIVED THREAD] - M4LEPII Canted Piston Gas Block

Posted: 3/22/2012 1:44:37 PM EDT

My M4LEPII has a pinned piston gas block that is twisted just slightly right. It bothered me a little bit that the K7 rail, never lined up with both the upper and gas block perfectly but not enough to push me to do anything about it, until I added an offset front sight onto it. Now it I have to set the rear windage to it's maximum and it's still a little off.

How should I go about correcting this?

With help from CMMG customer service I got this corrected. They offered to do it for free and install my new hand guard if I sent it in.

Loosened the screws and removed the roll pins.

Lined up the gas block.

Set the screws.

Re-installed the pins.

Perfect.
