What Makes The Best Scope for 6.5 Grendel

Searching for the best scope for 6.5 Grendel can be overwhelming. There are a ton of amazing options in the market, each better than the other. While shopping, to make the best choices, here are some factors that you should look for to get the most of your money:

  • Eye relief 

Eye relief can vary between brands and models of scopes. If the scope's eye relief is not sufficient, the top of the scope will hit the eyebrow. Moreover, the rifle's recoil throws the scope backward, and to prevent recoil related injuries, longer and adjustable eye relief should be sought out. 

Typically, the more magnification a scope provides, the shorter its eye relief. Nonetheless, since 6.5 Grendel is a low recoil rebound, choosing a scope with slightly shorter eye relief will not cause much harm to the shooter. 

  • Mid-range magnification 

Since 6.5 Grendel is utilized more for target shooting and hunting purposes, the scope's magnification has to fit these purposes. The 6.5 Grendel cartridge is potentially significant for shooting up to 1000 yards, and for this, 10X-12X magnification would suffice. 

It is recommended for shooting at targets and firing-oriented gaming sessions to get at least 4X magnification at 300 yards. It helps to aim for smaller targets at mid-range, but higher magnifications can be used to spot moving animals.

  • Reticle 

BDC reticles, which can compensate for bullet drop and help in landing a shot from afar is used or illuminated reticles used to provide excellent accuracy during the dusk or dawn hours of the day; one should always try to find scopes with premium-quality reticles to improve the odds of success for their future hunting adventures.

Mil-dot reticles provide more clarity, especially when it is combined with the 6.5 Grendel. Suitable for long-range or competition shooters, it allows shooters to minutely correct elevation, both up and down, and also windage. 

  • Adjustability

Good scopes should have easily adjustable elevation and windage. Very few scopes offer proper elevation and windage correction along with parallax adjustment. The turrets for these adjustments should not be stiff. They should be easy to rotate, and at the same time, they should not easily change when dropped or bumped against something. 

Also, the dials for magnification should be sturdy as well. It should be easy to use and must be adjustable for the shooter while moving. Remember, shooters usually prefer scopes that have audible and tactile clicking movements while adjusting.  

  • Image clarity 

In general, the larger the objective lens, the more light enters the scope. This means more comfortable shooting in lower light conditions. Apart from the size, the lens should also be clear without tinting for the best light transmission. 

It is always better to choose a lens with multiple coatings. Also, the lenses should be free of warps to avoid image distortion. 

  • Lens coatings 

The best scope for 6.5 Grendel should have excellent lenses with multiple coatings. These coatings can be in place to prevent damage from moisture, dirt, and scratches. They can also protect the lens from the weather and harsh lighting that damages the image. 

Be sure to look for lenses that are coated with defensive substances that protect the image from glare and chromatic aberration. Looking for scopes with lenses enhanced in such ways makes shooting more precise and smoother. 

  • Durability 

Since the 6.5 Grendel is a low recoil rifle, shockproofing is less important than other rifles. That does not mean shockproof scopes should be ignored. Since it is better to be safe than sorry, a shockproof scope is a better bet because bumping and dropping of the scope can occur at any time. 

Also, make sure that the body of the scope is made from a lightweight and durable material. A lot of the scopes in the market are made from aircraft-grade aluminum, and it is a safe choice. Fog-proofing and waterproofing the scope also increases the durability of the scopes.   

  • Focal plane

There are two focal planes, and depending on where the reticle is located, the functioning of the scope changes slightly. 

  • In a first focal plane scope, the reticle is placed in front of the magnification lenses. This means that the reticle itself will grow and shrink in size on changing the magnification on a variable power scope. First focal plane scopes are usually more expensive than second focal plane scopes due to the difficulty involved in manufacturing processes. 
  • On the other hand, second focal plane scopes have their reticle located behind the magnification lenses. Since whatever the scope is viewing has already been magnified, the reticle appearance does not change as magnification power is adjusted. The reticle appears the same at any power setting.

Second focal plane scopes are better suited for hunting, but the first focal plane scope is ideal for long-range shooting. Thus, it all comes to personal preference while choosing the reticle positioning of the scope. 

Conclusion 

Hopefully, this article helps you in your quest to purchase the best scope for 6.5 Grendel. Most of the scopes suggested in this article are excellent mid-range and long-range scopes. These scopes pair well with the stopping power and accuracy of the 6.5 Grendel.
