from the date codes shes a 1973, here is another photo. The barrel and tube are finished in some sort of brown like the old double rifles, it has then been sprayed in Transparent Cerekote. Anxious to mount the Redfield I thought it was a 70-0M (I'm new to vintage Redfields I thought there was only Lyman66) but after looking at photos of members here "70-OM" it ain't that..

 

Have to find the proper screws by checking the length and making sure they are the proper thread. You can take the action apart and mount the sight then measure the amount that the screw come through the receiver wall and then cut them to the proper length. The "dummy" screw will get your the right thread... I don't remember what the screws are right off hand. If you look around you can find the target knob that will fit this sight. If it were me I would buy a Redfield 75 for a Remington target rife and use the top of it mounted to the side piece of your sight. That will give you a windage knob and screw. The Merit adjustable aperture you have pictured are rare and should be considered a small prize in itself.... Take your time and do it right....

You have purchased a really nice rifle and should have a great time shooting it...

Forgot to say the second screw is hidden by the graduated elevation slide. Take it out and the hole is visible.

 

Have a close look at the box .... I'd take a few for $7.95!

 

I think they #8-40,but can't remember for sure. As already advised you want to use most of the threads, but not let the screws come through to the internals.

Congrats Powder on the purchase... I'd love to find one of those Merit apertures

 

The last time I looked, the Merit website was active. meritcorporation.com It may show up as Via, which is an aperture they make for ARs.

 

I would call the screw style that you need a "slotted cheese head screw". The size is 6-48. (#6 screw 48 threads per in.)

 

My "New" toy Marlin and Vintage Redfield Peep Sight..

Nice rifle.

Mounting screws should be 6-48. Cutting them to length is easy but the trick is to find filster heads that will fit. Too wide can be turned down but too tall of a screw head can be problematic.

I “think” your sight is a Redfield 80 which offers a “quick release” button (similar to a Lyman 66) as an improvement over the 70. You might be hosed for the missing elevation knob. I know the knobs and elevation screws are the same for the Redfield 70 and 75 but I think the 80 is different. The elevation screw sticking out of the top of yours doesn’t look like what one from a 70 (only the portion below the arm is threaded with a collar on the underside to retain it in the arm when the knob is placed on top and held with a set screw.).

Sight is an RE-DEFOM model. I don't believe the elevation knob to be missing. That skinny screw is slotted and I believe it to be a "stop" screw. That sight is not a micrometer adjustable sight. There is no screw for windage. Loosen the locking screws for windage adjustment.

If you can find the screws easily your sight is an inexpensive but usable sight. However, a better sight is the Williams Fool-proof. It is micrometer adjustable for both windage and elevation and will not make you yank your hair out trying to adjust it for sighting in.

 

Thanks for all the help guys...

Marlin, thanks, thats a good idea.. on the link I found on the stock peep sight dummy screws it lists the thread info.. I can start there. "tinytree" here on a old thread said these peep sight dummy screws are "6-48" so one of the two answers ). A "target knob" ? You have my attention.. Redfield 75 top will attach to mine? Thats curious.. I like the idea of a easy fast windage knob.. good advice, do it right, indeed...

Pickle, indeed 7.95... I've tried to figure out what era this box/price is from but failed, I'm guessing 1970s by the style of the box? Love the price though.

0605 thanks, I lucked out on the Merit... I just lucked out again and have this Redfield version too check it out.. I think its from the Olympic Palma..ebay buy it now.

 

What a great find on both the rifle and the perp! Good luck with the search for the receiver screws for it.

 

Old wound, Thanks!yea the size seem to be correct and I had no clue what those screws were called.. but that seems to be right from photos I've seen. "slotted cheese head screw" lol almost sounds like a joke but those are the ones I'm looking for. Thank you this gives me a very good start!

Also what is a "stop screw" your right, the top of that tiny screw is slotted..

I'll look into the Williams Uber Peep widget.. sounds interesting. I'm curious if I could mount either one of my adjustable aperture widgets on the Williams? Thanks for the help guys..

Next step is to get the rest of my reloading stuff, I still have some killer accurate loads that are usually the bomb in 336 Marlins accuracy wise.

 

Also what is a "stop screw" your right, the top of that tiny screw is slotted..

The little slotted screw is used to "stop" downward movement of the "L" shaped piece within the base. It can be used to make small adjustments in elevation. In use, you would slightly loosen the lock screw on the side of the base and make your small adjustment with the little slotted screw(up or down). Now apply a little pressure to the "L" shaped piece bringing the little slotted screw down until it contacts the base and "stops" the "L" piece, now tighten the lock screw.

The base screws might be tough to find as they are sight model specific. You may find them at a Ace hardware type store but I have doubts as 6-48 is a "National Special" size. Unless you get the right ones plan on modifying them to suit your needs. If you strike out finding them PM me as I MAY have something you could use or modify but you will need take some accurate measurements. IIRC I have a pill bottle with a bunch of that style gun screws. Just getting the Williams Fool Proof sight or the sight of your choice will save you much time, aggravation, and get you shooting sooner.

Usually the adjustable apertures are used in conjunction with a globe type front sight for competition use. For hunting purposes you (IMO) should not use the apertures and just use the part they screw into for sighting.

Have fun...

 

I use the Williams 5 D receiver sights a lot and that looks like Redfields version. Probably slightly heavier built. What they called the "stop" screw is a handy elevation screw as you can turn it a time or two for elevation and then push the sight up or down to the screw. You do have to loosen the screw that locks the elevation. Windage can be a bit of a PITA but really once it is in it is in. My 5 D' are on 4 different rifles and work just fine. Once sighted in they stay. Elevation is a simple adjustment for different loads, but often the rifle is used with one load anyway. The more adjustable sights are for those that do a lot of range shooting and play with different loads.

Powder, you might check your local hardware store for the screws ,I was looking for the same screws and that's where I found them

 

Power you did good very nice find. Congrats.

 

Local ACE has gunsmith screws now. They can be shortened if needed.

DEP

 

MF72... I never thought of that.. thank you! Really good idea..I'll give it whirl.. Thanks for all the great ideas. I think I might even try to find a cheap Redfield 75 to adapt to it.

ACE keeps popping up in conversations, we have one near by I go to. I'll swing by tomorrow and check. I never would have guessed they had gunsmith screws!

Oldwound thank you!! I'll keep you in mind if I fail horribly. Ditto, unfortunately, you are probably right about getting a Williams.. I admit my fault, I have this heavy strong nostalgia for a sight of any kind marked "Redfield"... my first and main deer gun is a Remington (from the good days Pre-we screwed and bought Marlin lol) model 7 in 7mm-08 I've killed ALL my deer with that gun and the original Redfield scope it came with used..my first hunting was with a borrowed Marlin 336...then my dad got one.. we never killed anything with the Marlin but those times with the Marlin trying to get a deer I want to revisit and succeed.

I'll try to get this sight/set-up but may end up with the williams or a OLD STYLE STEEL LYMAN 66. Thanks for the advice and help.
