Scope mount?

[crow#2]

My 39a is a 1952 model. One screw in top of receiver but its for securing cartridg guide. The way the receiver curves upward i will need to rework a rail or something.looks like i will only get 2 screws in the rail and back towards the stock.Will have to have 2 screw holes d&t. Any i deas? Anyone familiar with yhis model

Leave it alone. That is too nice of a rifle to mess up trying your luck drilling on it. Just my opinion. Buy one made to mount a scope on. Keep that one a classic.

 

[contender]

I concur,, I would not drill & tap that nice old Marlin.

Looking at 39As of similar vintage, it appears your rifle should already be D&T'd for a peep receiver sight. I'd go that route before I mucked up a nice rifle attempting to drill holes for a scope mount.

 

[crow#2]

1952 was when a change came about. Its not D&T
It has one d&t hole in top and thats for the screw that holds the cartridge guide.

Have you shot the rifle? Does it need a scope. I agree, just put peep sights on it.

 

[crow#2]

Its got a peep but my eyes are not to good. I shot yesterday at 20 yards and had 4 shots touching #5 almost. I can make a bracket/mount to mount where the peep is and secure my scope rail to it and put a layer of something under it as to not scratch up receiver. Got it designed in my head. Now its either aluminum or steel. I can polish and blue the steel.
Never tried blacking aluminum.

Weaver used to make side mounts for leaver rifles. Do some research on them. BTW, I'm older than your 39A and use peep sights on several rifles. I killed a mule at a little over 150 yards with a 45/70 and peep sights. All it takes is practice.

 

[crow#2]

I could handle that with big game but my problem is squirrels heads at 30 to 40 yards

 

[Papalote]

You must have some tall trees. LOL

 

[375hh1973]

Its ur rifle, do with it what you want. If it was mine and I wanted a scope, it would get a scope. Its yours for you to use and enjoy

 

[Hvymax]

Sell it to someone who can use and care for it properly. Plenty of newer ones ready to go the way you want. You'll only wreck any value it ever had to accomplish little to nothing.

 

[crow#2]

so heres a couple pics. I know its not machine like most of you do but wait until i get it all filed and smoothed out. On the left side the peep sight will go and this bracket will mount using factory holes which is where the peep sight is mounted. On the other side you only see the thickness of the bracket. The rail will be mounted to the top rail of my bracket.

Redneck hillbilly engineering
LOL. So im not bungling this nice old gun up.

 

[NikA]

Better an ugly scope mount than an ugly gun. The AlumaBlack stuff that Brownells and others sell is way more durable than cold blue in my experience.

 

[crow#2]

My mount looks ok but im picky. Will probably make another. The 90 degree bend is rounded looking not a nice square look. If i dont get one made to suit me i will forget it.i dont have a mill or anything but i do have a nice drill press and nice cross type vice. Its kinda hard doing it by hand. Thanks guys. And im not drilling any holes.Its bracket or peep

 

[MHtractorguy]

I bought a 1022 rather than try to scope a 39A.
I like the 1022 so well, I sold the Marlin.

 

[crow#2]

Well the mount is looking better. Now if i can find the screws i need.

 

[crow#2]

New pics just waiting on a 6/48 tap so i can secure my homemade bracket to the top rail.
Again no holes drilled in receiver.What do you think? If i could blue/ black the bracket better. May take it off and spray with flat black.I amp putting masking tape on the back of bracket so not to scratch the receiver. Temporary......what would you use permanently between bracket and receiver? Ive been thinking duct tape sticky side to bracket. Non sticky against receiver.
Wish i had the tools and knew how to use mill , lathe and all that.

 

[Hvymax]

Why don't you just get a full quadrail forend and a folding pistol grip stock with the thing that goes up?

 

[crow#2]

Made a new one.

 

[Papalote]

Main thing is to get it centered with the bore and level with the frame.

 

[crow#2]

Yep thats the hard part

 

[crow#2]

Dave as of now just a shim spacer. Like a round faucet washer. Im thinking of leaving that section of the bracket long enough to drill and tap the dove tail blank
and crewing the front part of the rail to it.The way it is now is alotcsturdier than you would think.Actually i shortened the bracket and the entire rIl on to rests on the receiver and barrel. I will send you a good pic. When done

 

[RoninPA]

What's going to support the forward portion extending over the barrel?

What I would do is to drill and tap a hole through the forward part of the rail and the bracket, then put a machine screw with a rubber tipped end (or some silicon sealant) through it and tighten it against the barrel and Loc-Tite it when you are happy with it. That front screw could help you level the rail in relation to the receiver.

 

[crow#2]

You are right. Ive been thinking along those lines.

My suggestion exactly. I prefer a set screw with a nylon end- I get these on some AR15 receivers to tighten upper to lower play.

Warning- don’t tighten this too much as it can induce a bow in the scope rail and potentially mess up your scope tube. You want just enough tension to stabilize the unsupported end of the rail and minimize harmonics.
