Weaver K6 Scope Review

The Weaver K6 6X38 is a classic, fixed power scope built with air-craft grade aluminum and fully multi-coated optics. It is ultra-light and extremely shockproof, designed to hold zero, even during heavy and repetitive recoil - how heavy and repetitive? You’ll have to keep reading the Q&A’s to find out.

The K6 rifle scope is hugely popular for many hunters out in the open field. For a no-fuss, user-friendly scope, you can't do better than this. Lots of reviewers online completely agree with the no-frills approach and genuine quality of this Classic K scope, they have given it a great rating and have nothing but good things to say about it.

This K6 had to be included in our Weaver scope line-up because of its overall popularity with mid-range to somewhat long range hunters. The ease of use, image quality, and low cost are the three top reasons this rifle scope does so well in the optics industry, and it's for those same reasons it earned its review.

Weaver doesn't need to dress up a scope that's a genuine beauty in itself. If you're not used to seeing a review that doesn't sugar-coat for marketing tactics, then the following Q&A is for you. You may be surprised with what Weaver can concoct with the fundamental basics that make good scopes an excellent pair of eyes.

K6 6X38 Rifle Scope Q&A:

What is different about the K series rifle scopes?

The K series rifle scopes are made for open field hunters that want something simple and easy to use. While it might seem like the K6 model is nude of anything special or unique, hunters that appreciate the clean contours that come with a compact and light-weight scope, see the full potential this model has.

The K6 has a fixed power scope of 6X magnification. While some hunters lean towards the 4X, the 6X gives you an advantage in 150-200 yard shots, or more if you've got the skill and the rifle to get it done.

Some hunters who mount their scopes to "carry-around" rifles, don't even get the chance to play around with variable power ranges anyway. And, the fact that its not dressed up in fancy trappings, makes for a super light scope of 9.8 ounces - a perfect weight for your perimeter hunting to keep the coyotes away.

Will this scope hold up to recoil?

This K6 rifle scope can withstand heavy recoil and still hold a zero, even for how small it is. Weaver ran some impressive tests for a scope in this price range that included 10,000 rounds from a .375 H&H magnum rifle. The results? I'll put it this way - if it didn't pass that test, it wouldn't be featured among our top rifle scopes. Still not convinced?

Maybe you can relate to other hunters that put this scope through the ringer by having it bounce around and take a beating while sitting in the bed of a truck or an ATV in rough terrain. This Weaver K6 rifle scope was made to take abuse. So, if you have some pretty punishing hunting conditions in the near future, Weaver says "Bring it on".

How much does this Weaver Classic K rifle scope cost?

This K6 6X38 mm rifle scope costs less than $200 - around $160 online. Buying direct from Weaver will put you up another $100-ish, but finding Weaver scopes for sale online, you might find it for much cheaper than that. The money that was saved by building this scope in Japan went into quality versus the "feature hype" that's often done with marketing gimmicks that can end up being short-lived scopes.

With the K6 rifle scope, you have quality glass to get you exactly what you need without spending a dime more.

Does this scope have finger adjustment turrets?

No. The Classic K series rifle scopes don't have finger adjustable turrets. Instead, they feature what you would call a coin slot type control where you can use a specialized tool, flat head screwdriver, or a coin to make scope adjustments.

If you could use finger control to make the adjustments, zeroing in would be done in a jiffy. But, the coin slot style also is what gives these Weaver scopes their renown reputation of keeping a zero under some harsh recoil. Remember, the K series is also about keeping it as simple and affordable as possible.

Is this Weaver scope long enough for a long action rifle?

This newer line of the Classic K series rifle scope has a compact and very light weight build, giving it an overall length of 11.32 inches and an eye relief of about 3.15 inches. They're shorter than the original and discontinued older K series. So unfortunately, if you had a previous K series rifle scope, you'll need new bases to install the new K6 scope.

But, don't let that get you down. The K6 is super easy to install and the set up instructions are clear and easy to understand. Bottom line here? While these measurements work for lightweight rifles, you'll need the right mounting system, perhaps base extensions, for long action rifles in order to ensure it's been mounted properly.

Noteworthy Features:

  • Fixed 6X to get right on target no matter the distance
  • Compact and lightweight at almost 10 ounces for lightweight rifles
  • Fully multi-coated lens for excellent clarity and brightness comparable to other big brands
  • Fully shockproof; keeps zero even during heavy and repeated recoil
  • 1/4 MOA positive clicks for windage and elevation adjustments
  • Backed by Weaver's limited lifetime warranty

Our Verdict on the Classic K6

According to the bull's-eye, you'll hit it every time with the Weaver K6 if you're taking shots within sub-250 yards. Yes, because of its compact design, you'll have to get base extensions to ensure decent enough eye relief.

If you don't want to bother with that, just go with the economical Weaver Kaspa 3-12X50 rifle scope. It has a few more inches on the K6, but you will be doubling the weight.

We haven't yet found another fixed rifle scope that we felt was worth featuring, so to come close to the specs, you could always consider the Vortex Crossfire II 2-7x32 rifle scope. It's cheaper than the K6, and it's a Vortex!

Weaver has expanded their sport optics into the hunting field versus their reputation with high-end tactical scopes. Now, they're bringing a whole new meaning to open field hunting with the K6. Are you ready to get your game on?

The Weaver K6 scope has been discontinued. Sticking to a fixed 6X magnification, why not check out the Primary Arms 6X42 rifle scope with ACSS 22LR Reticle at Optics Planet and Primary Arms.
