A little off topic hoping to gain some knowledge , Remington 212 SB Routledge bore . This rifle has a raised full length rib that is actually inleted into the top of the receiver. The rib is said to be factory? It is marked simmons gun did simmons install these for Remington? The gun also has a couple of small holes in the ejection port where these holes for some sort of shell deflector or catcher ?

I think this one is right up Gene's alley , hopefully someone here has info?
