Marlin 39 scope mount results?

Hi, folks,
I have seen a Weaver scope mount for the Marlin 39A which screws
to the barrel, and locates the scope on a rail that extends back over
the action, but does not actually attach to the action. I tend to need
a lot of flexibility in mounting scopes due to head position/eye relief,
and this looks like it might help if it works.

Has anyone used this scope mount, and if so, was accuracy good?
Any problems?

Thanks much,
John

John,
I don't think I've ever seen a mount like you're talking about, but the one I have on my M39 is just opposite of what you described. Mine attaches to the receiver via the holes drilled there and has a portion that extends out over the barrel almost to the point that it touches the rear sight. Mine works fine. It might be a Weaver but it's been so long since I put it o I really don't remember.
My M39 is probably the most accurate .22 I own and really starts to come into it's own once the scope is on it. I'd have to say that it even shoots as good or better than my 10/22 that I added the bull barrel to.

I've adapted that mount to many other normally hard-to-scope rifles, and found it perfectly suitable/usable, except for it's high gloss finish - which looked OK on some rifles, but contrasted badly with others.

IIRC, Some Marlin 39a's (I forget which years) had their barrels factory D/T'd for a scope mount for (Sears ?) - and most likely used that base or the Weaver side-mount base(I dunno which).

I have a "cantelever" mount like that on a couple 12-gauge slug guns, and they seem to hold up fine. Mine were sweat-soldered, it looks like, but for a .22 I'm sure screws should hold such a mount just fine.

I'd stick with a light scope though.

The other option since the top of the gun is flat would be to get an extended section of blank "weaver rail" and drill it to match the receiver, letting it hang forward over the barrel. (I take it you want a very forward mounted scope.)

If you don't mind a rather high mounted scope, there are also "offset" rings which move the mounting position about 1" forward or rearward; some are made which mount directly to the 1894, and I suppose the 39a.

This sounds like the mount that Marlin provides with the current version of the 39. It has a standard Weaver rail, so you can use generic rings.

I might have ordered this one from Marlin, I'm not sure. It does have a cantilever look to it though. In fact that's what it reminded me of when I put it on. I DO remember that much.

Hi, folks,

Thanks very much for the help! Glad to hear it sounds like there should
be no problem with accuracy or zero changing.

Take care,
John
