Greys GR40 Fly Rod
GR40 range overview; length and line rating vary by model
A moderate-to-fast action, four-piece build and sensible fittings make the GR40 a tempting all-round fly rod. Just pick the version for your fishing — the little #3 and beefier #8 have very different jobs.
- Moderate-to-fast action with a high intermediate modulus carbon blank.
- Four-piece construction with section line-up marks.
- Anodised aluminium, saltwater-safe reel seat with twin locking nuts.
- AAA-grade natural cork handle and an included Cordura rod tube.
Make sure it’s the right one. This covers the Greys GR40 fly rod range rather than one length and line rating. The #7 and #8 models have Full Wells handles and removable handle extensions.

Who it suits
Is it right for you?
Great for
- General fly anglers choosing a rod for a clear job. The moderate-to-fast action and practical fittings make a sensible starting point, provided the model matches the water and flies.
- Anglers travelling between waters. Four-piece construction and an included tube keep transport less awkward than carrying a longer, fewer-section rod.
Maybe skip if
- Anglers after a very soft or particularly fast specialist action. The GR40's moderate-to-fast brief sits between those more distinctive preferences.
- Anyone expecting one model to cover every fly-fishing job. Small-stream presentation and heavier-line work put very different demands on rod length and line rating.

Quick verdict
A sensible all-rounder — in the right size
The GR40 has a properly useful mix of features: a moderate-to-fast action, four-piece construction, natural cork and a protective tube. It makes sense for anglers after a conventional fly rod with straightforward, practical fittings.
The big decision is which model to buy. Match the length and line rating to your water, flies and casting space, rather than grabbing the most powerful version and hoping it covers everything.

The carbon blank, natural cork and anodised aluminium reel seat make a well-considered build on paper.
The moderate-to-fast action offers a useful general-purpose brief without being a specialist answer to every casting style.
A correctly chosen model supports suitable presentation and line control, but fly choice and watercraft still do the heavy lifting.
Alignment marks, twin locking nuts and four-piece transport make the practical side refreshingly straightforward.
The included tube and useful fittings strengthen the package, though the actual deal depends on the asking price.

The full rundown
Everything you'll want to know about the Greys GR40 Fly Rod
The Greys GR40 is the sort of fly rod that makes most sense when you start with a simple question: what fishing are you actually doing? Not what you might fancy once in a blue moon, but your usual water, flies and casting space. This is a range with different lengths and line ratings, not one magic wand for every session. Get that choice right and its moderate-to-fast action, four-piece build and practical fittings make a pretty sensible package. Get it wrong and a tidy badge won't rescue the mismatch.
That moderate-to-fast action is the main talking point. On paper, it puts the GR40 between a deeply bending, leisurely rod and a particularly fast, demanding one. That's a useful brief for general fly fishing, where you might want controlled presentation one minute and a bit more line speed the next. Don't read it as a promise of effortless distance, though. Your timing, the fly line's head design and how much line you've got outside the tip all play their part. Smooth acceleration beats trying to wallop the thing.
The blank is high intermediate modulus carbon. That's a construction detail, not a shortcut to knowing exactly how every model will feel in your hand. Length and line rating still change the job considerably. The confirmed 7 ft 6 in #3 points towards lighter lines and smaller-water work, particularly where a longer rod becomes awkward around vegetation. The 10 ft #8 is a very different proposition, giving you a longer rod built for a heavier-rated line. Think about the flies you need to carry, not simply the biggest fish you hope to hook.
If you're coming across from carp or coarse fishing, the line number needs a little explaining. A #3 or #8 isn't a breaking strain or a test curve. It's the rod's intended fly-line weight class, and matching the outfit properly helps the blank load during the cast. A heavier number isn't automatically better, mate. Using more outfit than a delicate presentation needs can make the whole exercise clumsier. Equally, asking a light-line setup to carry bulky flies in a breeze is a cracking way to turn a relaxing afternoon into hard work.
The four-piece construction is a proper practical plus. It makes the rod easier to stow for a trip, and the included Cordura tube gives you somewhere sensible to keep it protected in transit. Section line-up marks take some of the squinting out of assembly, too. Just don't confuse straight guides with properly seated joints: you still need to put each section together carefully and check things occasionally while fishing. A loose joint is nobody's idea of a useful surprise, especially when you're enjoying a decent spell of casting.
Down at the handle, you get AAA-grade natural cork and an anodised aluminium reel seat with twin locking nuts. Those two nuts give you a straightforward way to secure the reel rather than relying on one nut alone. The #7 and #8 models have Full Wells handles and removable handle extensions, so don't assume every GR40 has identical furniture. Handle shape is personal, but it's worth paying attention to when choosing an outfit you'll be holding through plenty of casts. Comfort matters more than a fancy-looking butt cap.
There are a couple of smaller details that make sense on the bank. Every model has a hook keeper ring, which is handy when you're moving between spots with a fly attached; just keep the hook point safely tucked away from your hand. The reel seat is described as saltwater-safe, but that's no invitation to leave salt drying on the outfit. A gentle freshwater rinse and proper drying afterwards are sensible habits. The laser-engraved fin logo on the butt cap is a neat finishing touch, rather than anything that'll help you tempt a trout.
Where does that leave the GR40? As a sensible candidate for someone who wants a conventional, versatile fly rod in a model chosen for a particular job. There's enough useful kit here to make the package appealing without pretending the fittings can fix poor line choice or rushed casting. If you've already got a reel and line, check their suitability before spending your quid. If you're starting fresh, choose the water and flies first, then build a balanced outfit around them. That's a much better route than buying power you don't need.

Our take
Choose the fishing first, then the rod
A 7 ft 6 in #3 and a 10 ft #8 might share the GR40 badge, but they're hardly substitutes. One points towards light-line fishing in tighter quarters; the other towards heavier lines and more reach.
The shared fittings are handy across the range. The handling you need still comes down to the individual model and a suitable fly line.
The build
Closer look: useful details, not just shiny bits
The GR40 combines a high intermediate modulus carbon blank with a moderate-to-fast action. That's a general-purpose brief rather than an extreme one. Don't pick it purely from the carbon description: the correct length, line rating and a line taper suited to your fishing are what make the outfit hang together.
The four-piece layout, alignment marks and Cordura tube deal with the travelling and setting-up side nicely. Twin reel-seat locking nuts help keep the reel secure, while the natural cork gives you a familiar fly-rod grip. Tighten things firmly by hand, without treating the reel seat like a wheel nut.
Worth knowing. The Full Wells handle and removable handle extension apply to the #7 and #8 models. Don't assume a photo of one of those versions shows the exact handle arrangement on every GR40.
Pick your job
Who it suits: anglers buying for their usual water
For lighter fishing in confined surroundings, the 7 ft 6 in #3 is the obvious confirmed model to consider first. A shorter rod can be easier to manage around overhanging cover, although you give up some reach for line control. Small water doesn't automatically mean short rod, either — bank height and the casts available still matter.
The 10 ft #8 points towards heavier-line fishing where extra reach is useful. That might suit some reservoir work, but it isn't automatically the outfit for every stillwater trout session. Choose around fly size, line type and conditions. If your fishing is mostly delicate work with small flies, extra power can be more burden than benefit.
Beginners and occasional fly anglers have good reason to consider the range, provided someone helps match the outfit sensibly. Specialists who already know they want a very soft action or a particularly fast casting tool may prefer something more focused. Spend on the right fit, not on imagined extra yards.
Before you buy
FAQs in full: getting the outfit right
Is it beginner-friendly? The moderate-to-fast action gives the GR40 a reasonable general-purpose starting point. Start with the rod's stated line rating rather than changing line weights to fix a casting problem. A short lesson on stopping the rod and letting the line straighten can do far more good than another tackle purchase.
Which version should you buy? Decide where you'll fish, how much casting room you've got and what flies you'll use. The 7 ft 6 in #3 and 10 ft #8 show just how different the range's jobs can be. Check the individual model carefully, especially if you're matching it to a line and reel you already own.
Is it suitable for saltwater? The reel seat is anodised aluminium and described as saltwater-safe, but that feature alone doesn't establish suitability for a particular species or fly size. Match the whole outfit to the job. Afterwards, rinse gently with fresh water, let everything dry and avoid shutting a damp rod straight into its tube.
On paper
Pros & cons
What we like
- Moderate-to-fast action offers a sensible middle ground for general fly fishing.
- Four-piece build and included tube make transport straightforward.
- Line-up marks and twin reel-seat nuts are genuinely useful details.
- Model choices cover distinctly different light- and heavier-line jobs.
Worth knowing
- A general-purpose action won't satisfy every specialist casting preference.
- Four sections mean more joints to seat and check than a two-piece rod.
- The different lengths and line ratings aren't interchangeable — buying the wrong model is an expensive shortcut.

01Is the Greys GR40 suitable for a beginner?
Is the Greys GR40 suitable for a beginner?
It's a sensible option in the right model. The moderate-to-fast action is a reasonable general-purpose starting point, but a matching line and a bit of casting tuition matter more than the badge.
02Which GR40 model should I choose?
Which GR40 model should I choose?
Start with your water and fly size. The confirmed 7 ft 6 in #3 points towards light-line fishing and restricted spaces, while the 10 ft #8 suits heavier-line work where extra reach is useful. Neither is a universal choice.
03Can the GR40 be used in saltwater?
Can the GR40 be used in saltwater?
Its anodised aluminium reel seat is described as saltwater-safe. That doesn't make every model suitable for every saltwater species. Choose an appropriate outfit, rinse it gently with fresh water afterwards and let it dry before packing it away.
