Lewis Machine and Tool MRP ejection port cover removal?

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?

They act only as retainers

Mine doesn't have a C clip like that.

Nor do mine, as far as i can see, on either my MRP's or MWS's, so I'm at a loss with that, too.

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 armored class, bad.

The rear roll pin is blind from the top and can only be seen from the bottom. I have no idea how you'd remove it, but the front roll pin can be driven down from the top.

I just shined a light into the bottom of the pin, and it comes through the hole at the top, so you must have a different generation upper than I do.

Interesting, both of my MRP's have the blind rear pin by the case deflector.

The one I shined I bought about 12yrs ago, the other, 10yrs ago, so they ain't new at all.

Could they be screws?

I thought of that too. I need to get my nylon brush and brush away some funk to be 100% positive

Yes, they are roll pins

I am pretty sure that you tap the forward roll pin up and that will allow the ejection port cover rod to come forward and then swing out from the receiver. You should then be able to tap it back into place without issues.
