I've spent a lot of time testing different scopes, but setting up the axcel avx 31 really changed how I approach my target shots. It's one of those pieces of gear that looks simple enough until you actually get it in your hands and realize how much thought went into the little things. Most of us who have been flinging arrows for a while know that the scope is the window to your performance, and if that window is blurry, cluttered, or just plain fragile, your scores are going to suffer.
When I first pulled the AVX 31 out of the packaging, the thing that struck me most was the build quality. It's got that solid, machined feel that tells you it's not going to rattle apart after a hundred shots. Axcel has a reputation for over-engineering their stuff in the best way possible, and this scope housing is no exception. It's built from 6061-T6 aluminum, which is basically the gold standard for high-end archery accessories because it's light enough to keep your bow balanced but tough enough to handle a bump against a tree or a stabilizer rack.
Why the 31mm Size Hits the Sweet Spot
Size is always a big debate in the archery world. You've got the guys who want a massive field of view with a 41mm housing, and then you've got the purists who want a tiny peep and a tiny scope for maximum focus. For me, the axcel avx 31 sits right in that "Goldilocks" zone.
At 31mm, you're getting a housing that is easy to center in a standard 1/8" or 3/16" peep sight. If your scope housing is too big, you end up with a lot of "daylight" around the edges, which makes it harder to stay consistent with your eye alignment. If it's too small, you feel like you're looking through a straw. The AVX 31 gives you enough peripheral view to see the target and the wind flags, but it's tight enough that your brain naturally centers it. This is a huge help when the pressure is on during a local 3D shoot or a high-stakes tournament.
Co-Planar Technology and Why It Matters
One of the features that Axcel brags about with this model is their Co-Planar Technology. Now, that sounds like a bunch of marketing jargon, but in practice, it's actually pretty clever. Essentially, it means that the lens and the ring are on the exact same plane.
Why should you care? Because it eliminates a lot of the visual distortion you get with cheaper scopes. When the lens sits offset from the housing or the pin, you can get weird reflections or a slight "fisheye" effect if your eye isn't perfectly centered. With the axcel avx 31, everything is squared up. It makes the target look flatter and clearer, which helps a lot when you're trying to pick a tiny spot on a dark 3D target at 40 yards.
Customizing Your Aiming Point
Another thing I love about this setup is how much you can mess with it to make it your own. It's not a "one size fits all" piece of gear. You can run it with just a lens and a sticker dot, or you can go full-out with a fiber optic pin and a rheostat light.
If you're a fan of fiber optics, the way the AVX 31 handles the fiber is excellent. It uses a T-connection that keeps the fiber protected but allows plenty of light to hit it. I've used scopes in the past where the fiber was so exposed it would snag on every branch I walked past, or so tucked away that the pin looked dead in anything but direct sunlight. This housing strikes a really nice balance. Plus, if you add the rheostat cover, you can manually dial down the brightness. There's nothing worse than a pin that's so bright it "starbursts" and covers up the entire bullseye. Being able to dim that light down on a bright summer day is a game-changer.
The Ease of Adding Lenses
If you're moving into the world of magnified optics, the axcel avx 31 makes the transition pretty painless. It's designed to take a variety of lenses, including the popular Doc's Choice glass. The way the lens retains in the housing is secure—you don't feel like you're going to strip a screw or crack the glass every time you want to clean it.
I usually run a 4x power lens, and I've noticed that the internal diameter of the AVX 31 helps keep the glare to a minimum. Axcel also offers sunshades and stepped baffles that screw directly into the front or back. If you've ever shot on a field where the sun is hitting your scope at a weird angle, you know how annoying glare can be. Being able to just screw on a shade without needing a bunch of tools is a nice touch that I've come to appreciate.
Field Performance and Durability
I've taken the axcel avx 31 through some pretty rough conditions. From humid mornings where everything is covered in dew to dusty afternoons on a dry range, it holds up. The finish doesn't flake off, and more importantly, the adjustments stay put.
One thing that people often overlook is the torque indicator. The AVX 31 has a clearly visible ring that helps you identify if you're torquing your bow grip. It's a small visual cue, but when you're tired at the end of a long round, it's a great "idiot check" to make sure your form isn't slipping. It's those little intentional design choices that make me keep coming back to Axcel gear.
Setting Up Your AVX 31
When you actually sit down to mount this thing to your sight bar, it's a straightforward process. It uses a standard 10-32 threaded rod, which fits almost any modern target sight. I've got mine mounted on an Axcel Achieve, and the integration is seamless.
I'll give you a small tip, though: when you're setting your level (the 3rd axis), take your time with the AVX 31. Because the housing is so precise, any slight tilt is going to be obvious. Make sure your bubble level is calibrated correctly. The level vial on the AVX 31 is high quality and easy to read, but it's only as good as your initial setup. Once you have it locked in, it doesn't tend to drift, even after thousands of shots.
Is It Worth the Investment?
Let's be real—archery gear isn't getting any cheaper. You can definitely find scope housings for half the price of the axcel avx 31. But as the saying goes, you get what you pay for. With this scope, you're paying for precision and peace of mind.
If you're just shooting in your backyard for fun, maybe this is overkill. But if you're competing or if you're a bowhunter who demands the absolute best clarity for your setup, it's a solid investment. It's a piece of gear that grows with you. You might start with a simple pin and later move to a high-end lens and a light kit, and the AVX 31 will handle all of it without you needing to buy a new housing.
Final Thoughts on the AVX 31
At the end of the day, your scope shouldn't be something you're thinking about while you're at full draw. You want it to disappear and just leave you with a clear, confident view of your target. The axcel avx 31 does exactly that. It's rugged, it's customizable, and it's sized perfectly for most archers.
It's been a while since I've been this impressed with a "simple" scope housing. Usually, there's some small annoyance—a rattle, a reflection, or a weird mounting issue—but Axcel seems to have ironed out all those kinks. If you're looking to upgrade your sight picture and want something that's going to last for years, you really can't go wrong here. It just works, and in a sport where so many variables can go wrong, having gear you don't have to worry about is worth every penny.
