Most Helpful Positive Review Weaver "Old School" Classic
Got this Weaver Classic K-4 for a newly acquired Marlin 336 my boys will begin using this year. I grew up with an older version of this scope. It was mounted on my dad's Model 88 .243 Winchester. My three younger brothers and I all used it throughout our teenage years...and we all know what teena...

Most Helpful Negative Review Dissapointed
This scope has the same problem I had with a Leupold VX1 and a Redfield. In some lighting conditions, light intrusion makes the reticle appear copper colored instead of black. I have a Chinese made Weaver and it is not like that. Pros: Good Japanese Glass Cons: Reticle too fine for low light in brus...

Tough scope

by James, Verified Owner from SC, United States Written on November 26, 2017
This is my second purchase, the first went on my 45-70 marlin guide gun. I zeroed it, and it works great, holds it's zero through several hundred rounds. I like the fixed magnification and simplicity, point and shoot.
Pros:
  • Clear
  • Tough and dependable
Cons:
  • None
Best Used for:
  • hunting
Would recommend: Yes

great scope for the price

by Christian, from FL, United States Written on August 12, 2017
I was very surprised by how clear the glass was on this sub-$200 scope. I think the fixed power simplifies the manufacture of the scope and lets weaver invest more money into the glass than if it had variable power.
Pros:
  • Glass clarity
Cons:
  • None
Best Used for:
  • hunting
Would recommend: Yes

Just like it's name, still a "Classic".

by Michael, from FL, United States Written on December 24, 2016
The old family .270 (Herter's XJ-3) had a Weaver 4X scope on it and it performed flawlessly through many decades of hard use (airboat, swampbuggy, hundreds of miles of walk and treestand hunting in the Big Cypress, a dunking or two, etc). Simple and efficient for this environment/type of hunting. Finally wore out, the reticle, but still air/water tight. Decided to 'upgrade' to a 3 X 9. Just wasn't the same. The 4X is perfect for this close in/low light hunting. And due to the excellent history and performance of the first Weaver 4X scope decided without a second thought to buy a Weaver again.
Pros:
  • simplicity
  • Proven history
  • Known performance
Cons:
  • None
Best Used for:
  • Close-in situations
  • Quick sight on
  • Low Light (dawn/dusk/oak hammock/cypress sloughs
Would recommend: Yes

A good value

by MJK, Verified Owner from NJ, United States Written on December 20, 2016
I bought this scope for a hunting rifle and needed a fairly long scope. This model compares well to my Leupold 4x scopes (I have two) and is nearly half the price. A fixed power scope is far less likely to fail in the field than a variable. 4x is plenty enough for hunting out to any reasonable range.

Elk hunter

by Nort, from AZ, United States Written on August 24, 2016
The Weaver K-4 I bought replaces a Weaver K-4 I bought in 1960. The K-4 I had was refurbished at the factory 20 years ago. I don't know if this one will last that long. I know I won't be around that long. The one thing I like about this single power scope is the wide field of view.
Pros:
  • wide field of view
Cons:
  • None
Would recommend: Yes

Not a Leupold

by steve, from WA, United States Written on January 8, 2016
Cracked the lens on my old Leupold 4x somehow, so bought the Weaver to replace it. The Weaver may be a great scope for the money, but after nearly 30 years with my old Leupold I can tell you the Weaver in not in the same class. Optics just plain aren't as good. Plus, the Leupold was nice and compact, the Weaver seems to be at least an inch longer.

So, returned the Weaver and sent the Leupold in for repair. If you were buying new I realize the Leupold is twice the price, but if you keep the scope for 30 years the extra $150 doesn't mean that much.

Optics Planet was very good to work with for the return and I will be shopping here for my optics in the future.

Weaver Classic K-4 4x38mm Dual-X Rifle Scope

by loader, from SC, United States Written on October 25, 2015
Mounted this scope on my marlin 336/ .30/30. Sighted in easily and adjusted properly. Very clear and bright.
Have the 6x version on a Remington 700 in .223 been using for 3 years and close to a thousand rounds it never had any sift in zero. Looking forward to equal performance from this one.

Weaver Classic K-4 4x38mm Dual -X Rifle Scope

by Jerry, Verified Owner from FL, United States Written on July 23, 2015
I bought a Weaver K-4 rifle scope back about 1970 and mounted it on my Marlin 336. At the time, that was the scope to buy. I had a problem with it fogging up when the weather got a little cold. So, I sent it back to Weaver. After getting it back, I had the same problem. I haven't bought a Weaver scope since until about a year ago when I purchased two T-Series scopes. I love them. I figured it was time to bury the hatchet. Buying two Weaver Classic K-4s, I mounted one on the old Marlin 336 which I had given to my son and the other I mounted on a Winchester 94 AE. We plan to use them this deer season. I shot both guns in and the scopes were perfect. This time, I think I made a good purchase.

WEAVER K4 4X-38 MM

by Rick C., from WV, United States Written on November 29, 2014
Weaver has always made a very high quality scope , both for hunting and benchrest target shooting....they just don't put the money into advertising as much as NIKON or LEUPOLD .
The optical & mechanical quality is every bit as good .
