S&W M&P15T Gas Block Removal

[hobit]

Has anyone here removed the above mentioned gas block? Looks like 2 set screws on the bottom and a tapered pin holding it to the barrel but there is also a small roll pin up where the tube inserts into the block, is this holding the tube in place? Any tips or advice would be great. Thanks all.

The roll pin holds the gas tube to the gas block. It is standard arrangement.
