Buying Guide: What to Look For in a Scope for Your 6.5 Grendel
Choosing the right glass for your 6.5 Grendel is a big deal. I’ve spent a lot of time behind this cartridge, and getting the scope wrong can really hold back its potential. The Grendel is a fantastic round for medium to long-range shooting, whether you’re hunting deer or punching paper, so your optic needs to match its versatility. Here’s what I focus on when I’m picking out a scope.
First, think about magnification. The 6.5 Grendel has legs, but it’s not a dedicated 1,200-yard cannon. For most uses, a scope in the 3-15x or 4-16x range is the sweet spot. This gives you enough power to see your hits at distance but keeps the low end wide enough for closer shots or hunting in thicker cover. If you’re strictly a benchrest shooter, you might push for an 18x or 20x top end, but for a do-it-all rifle, stick with that mid-range zoom.
Next up is the reticle. A simple duplex is fine for hunting in the woods, but if you want to take full advantage of the Grendel’s ballistic prowess, you need a reticle with holdover points. I strongly prefer a First Focal Plane (FFP) reticle. With an FFP scope, the reticle’s size changes with the magnification, so the holdover marks are accurate at any power. This is a huge advantage when you’re trying to make a quick, ethical shot on an animal or engaging multiple targets at unknown distances.
Don’t forget about the turrets. Exposed, tactile turrets are a must if you plan on doing any dialing for elevation. You want to feel confident and hear a solid click with each adjustment. For hunting, a zero-stop feature is incredibly valuable. It lets you quickly return to your zero after dialing for a long shot, so you don’t get lost in the clicks when a buck appears at 100 yards.
Finally, consider the tube size and overall build quality. A 30mm tube generally offers more internal adjustment range than a 1-inch tube, which is helpful for stretching the Grendel’s legs. Look for scopes that are nitrogen-purged and O-ring sealed for fog-proof and waterproof performance. Your optic is an investment, and it needs to handle the recoil and the elements. After testing several options for our Top 8 Best Scopes For 6.5 Grendel [2025 Field Test], these are the factors that separated the good from the great.
FAQ
What magnification range is best for a 6.5 Grendel?
For a general-purpose 6.5 Grendel rifle, I find a magnification range of 3-15x or 4-16x to be the most practical. This gives you a wide field of view on the low end for closer-range shots or scanning, and enough power on the high end to clearly see and place shots on target out to 500-600 yards, which is where the Grendel really performs. If your primary use is varmint hunting or target shooting at known long ranges, you could go up to 6-24x.
Is First Focal Plane or Second Focal Plane better for the 6.5 Grendel?
For anyone serious about using the 6.5 Grendel for precision shooting at various distances, I recommend a First Focal Plane (FFP) scope. The big advantage is that the holdover points in the reticle are correct at every magnification level. This is crucial for hunting or competitive shooting where you might not have time to max out your zoom to use a BDC reticle. SFP scopes are fine if you always use one magnification setting, but FFP offers much more flexibility.
How much internal adjustment do I need?
You want as much as you can get, but a good minimum to look for is around 60 MOA or 18 MILs of total elevation adjustment. The 6.5 Grendel has a fairly flat trajectory, but to really reach out past 600 yards, you’ll need to dial your elevation turret. A scope with ample adjustment, often found in 30mm tubes, gives you the travel needed without having to use a canted base right away.
Can I use a .223/5.56 BDC scope on my 6.5 Grendel?
I would not recommend it. The ballistic trajectory of the 6.5 Grendel is completely different from the .223 Remington. The holdover points on a BDC reticle calibrated for a .223 will not match up with your 6.5 Grendel’s bullet drop. You’ll end up with inaccurate holds and missed shots. It’s much better to use a scope with a universal MIL or MOA reticle and learn your specific dope, or find a scope with a custom turret programmed for your Grendel load.
What is a good budget for a quality 6.5 Grendel scope?
You can find decent entry-level scopes in the $300-$500 range that will work, but in my experience, the performance and features jump significantly in the $600-$1,000 bracket. This is where you typically find better glass clarity, more robust construction, reliable turrets, and FFP reticles. When looking at the Top 8 Best Scopes For 6.5 Grendel [2025 Field Test], we considered options across this price spectrum to fit different needs and budgets.
