Lewis Machine and Tool MRP ejection port cover removal?

[INTrooper4255]

Does anyone know how to remove the ejection port cover on an MRP upper? I'm going to send mine off for Cerakote and it has to be stripped and the ejection port cover mechanism is different than a standard AR. I didn't know if you just removed the front roll pin and the cover came off or what? Any help would be appreciated, I came up with nothing on an internet search.

Do you have pics? I haven’t messed with an MRP, but I’d be interested in seeing what it is around the port cover

I believe you must first drive out the forward roll pin from the top with a long roll pin punch & then the port door assembly can swing out slightly & be removed.

That's what I was thinking, the rear pin is only exposed at the bottom and can't be driven out. Thanks

Scroll down to page 43... there is a tiny clip (4) on the forward end of the pin ( 5 ). Not sure if removing that will set it free or not. The roll pin ( 3 ) is named BOLT CATCH pin... not port cover retainer, soo....

Mine doesn't have a C clip like that.

Pretty slick. Does the dust cover pin have recesses / notches for the roll pins or do they only act as retainers against the curved surface of the pin / shaft?

I've never disassembled my uppers, but mine have holes at the top of the brass deflector that look like you could drive the pin out from them. Does yours have a blind hole drilled from the bottom? And I don't understand what anything in the upper has to do with the bolt catch.

I need to take the LMT armorers class, bad.
