Home Forums Lever Action Central Big Bore Levers I’m Marlin GC

Good afternoon gentlemen, I recently purchased a guide gun, ordered a Skinner peep site for it. The site came with 8-40 screws. The receiver has what I believe to be 6-48 screws, filler screws. Skinner said he never heard of that before. He’s going to send me out a site for a Rossi, which will fit but with 6-48 screws. anyone have any experience with this? Thanks.

No. I have handled thousands of Marlin Guide Guns and I’ve never seen one with anything but 8x40 screw holes in the factory locations.

Do the holes not line up or the screws are too big?

Hey kid, the holes lineup to the Skinner base. The filler screws on the receiver are way smaller than the screws provided by Skinner. I can put the Skinner screws into my 336. They are 8–40. I am assuming the screws on my 1895G, receiver screws are 6–48. I did not measure I am just assuming this. But the 8–40 screws that they provided do not fit on my 1895G… way too big. What do you think?

Strange. I can’t imagine how that came to be. As far as I know Marlin used 8-40s on all the modern centerfire lever action rifles that were factory drilled and tapped. Beats me

The gentleman at Skinner, Echoes exactly what you’re saying. He said he’s never heard of that before. He’s going to send me out a new site with 6–48 screws for a Rossi. He says it will fit. I’m almost tempted to retap those screws to 8– 40s, don’t know if I want to screw with that though. There is only going to be two screws holding that site on. 8–40 Is fine but 6-48 seems a little wimpy to me.

I’ve mounted scopes on much heavier recoiling rifles using 6-48s, I wouldn’t worry there. Just a really strange deal.

I agree, I haven’t gone crazy researching it when I get some time I’ll do it and see what I come up with. If you find anything out, give me a shout please I’m so damn curious on why that receiver has 6–48. Thanks for all your help Greatly appreciate it. Enjoy your evening.

I'd not hesitate one minute having a gunsmith with a mill open those holes up to #8. I do that every chance I get building a Rem 700. On your rifle two #8's are just better than two #6's.

I agree, I was seriously thinking about open them up. Still might do it, I’m in no rush we’ll see. Spoke to Brad over at tally, he told me that he thinks Marlin produced 1895s that were not drilled and tapped. So maybe somebody took it upon themselves and went with 6-48???

In that case I would have the hole alignment checked, or get after it with a dial caliper myself, before I did anything. Never know what Bubba done with his drill press.
