mounting a scope on a 39A/336



Log in to see fewer ads
on the top of my receiver there are 2 screws ( plugs ) missing. i'm assuming that that is where the scope rail mounts. i have the same exact configuration on my 336RC. would the same mount work on the 336RC? getting older has me scoping several rifles. when i test fired the 39A i was seeing ok on the 25 yard line but was a little hazy at 50 & hazier yet at 75 yards. the joys of aging eh?

From memory;

The 39a will need and 3/8" dovetail rail for rimfire mounts.
The rail will attach to the two screw in the rear and one in the front.
Many are made to cover the raised front section of the receiver.

Iím 99% sure the hole spacing is different between the 39A and the 336.
But for what itís worth , the 336,1894,1895 all use the same.
The good news is that both are available and neither are real high.

as mentioned in another thread i have a model 90 weaver scope base on it's way. i went over it's description & it nowhere mentions that it will fit the 336. i did find a leopold # 55910 base for the 336. i found a weaver base too but i'm not sure how a gloss finish base would look. i'm putting a weaver R-7 3-9 x 32 A.O. scope on the 39A. i have a older bushnell 4-12 x40 A.O. made in japan trophy for the 336.

I have the Weaver #90 for my 39a. I also have had mounts/rings on my 336, 35 Rem. for 25 years that are Redfield steel bases and mounts. The 336 numbers are Redfield 51223, JR 336-r base and Redfield 522635 1" split (medium) JR/SR scope mount rings. I am sure that some of these bases and rings are still out there with some searching. I also have a Redfield 4x post scope on the 336 in 35 Rem that is a great vintage set up on this rifle.

my first came with a plate mounted to those screws - it readily accepted scope moints designed with the claws for a grooved receiver , the second has the screws for mounting the plate but no plate , , i would like to think i could switch them if i chose to but i have no proof of that yet ,

Scopes sound great. The 32AO perfect for the 39A and the 4x12x40 good hunting set up.
For the lowest rings sometime the rear sight can get in the way or trigger space issues can occure,
I have had them forward or back enough with no issue but others either the buck horn or the Elevator would hit the front.

if the rear sight is an issue i'll remove it & store it. a funny story. the 336 came with the stamped steel rear sight. i decided to switch to the buckhorn sight. not knowing any better i did not replace the front sight. i was laying prone & shooting off a bag to zero the rifle. ten shots & i never touched paper. i stood up & watched as a 4" sapling teetered & fell. because i hadn't changed the front bead i was shooting dead center & 6" high. ten shots in a tight pattern was enough to drop the tree. unfortunately i cannot find the original sights. are the sights for a model 80 the same as the 39/336?

The rear sight changed alot.
A '65 336 rear sight was, I believe, a a Flat-bench with a V and a flat stamped elevator.
That may depend on the model, 336A, SC or W.
I don't know the 80 model.
