Today, I’ll tell you how the latest 3-9X32 UTG Bug Buster scope works in action. As you know, this scope was mounted on the Evanix Rainstorm 3D bullpup rifle that I tested for you yesterday. While shooting it, I had the opportunity to examine the performance of this latest Bug Buster scope in great detail, so now I can report on that, as well.
A world of improvement
The last Bug Buster scope I used before this one was a fixed 6x scope that’s now many years old. This new Bug Buster is very advanced from that one, though there are some things that haven’t changed.
The first and most obvious improvement is variable power. Of course, Bug Busters have had variable power for many years, but I think this was my first chance to really use one. In the old days, we were just thrilled to have a fixed 4x. It was the ability to focus down to just 9 feet that was the big sales feature of the Bug Buster, and we didn’t expect much more than that. But variable power is usually better, since it gives you the opportunity to choose where to set the magnification. That being said, I cranked this scope to 9x and left it there. I doubt there are many reasons for me to ever use the lower power settings.
Field of view
The Bug Buster has a field of view slightly larger than a scope of normal length with the same specifications. But in my experience, the exit pupil is more critical on the Bug Buster. In other words, your eye has to be in exactly the right spot or you can’t see the image. That was how the scope acted in the test of the 3D bullpup, but I don’t know if it was the odd hold I had to use with that rifle or not.
The whole reason I’m testing this scope is because of the new, finer crosshairs. I guess the small groups I got in the test attest to the fact that these lines are thinner and thus better able to parse the bull closer. I don’t know of a more dramatic way of demonstrating it to you unless you look through the scope yourself.
And, of course, the thin inner crosshair lines have mil-dots running in both directions. So, you can estimate range if you read and apply the data in the handbook that comes with the scope.
I was concerned that because I’m colorblind, the illuminated crosshairs would be of limited use to me, but that isn’t the case. While many of the colors do look alike at the lower power levels, I can see differences in all the colors at the maximum intensity. The 2-button system takes some learning, but turning on and off are both simple commands, so there’s no danger of running down the battery. And there’s a timed shutoff, on top of everything. I don’t think I would use the illumination most of the time, but it’s there if you need it, and the battery will keep a long time if not in use.
On the highest power illumination, the inside of the scope tube gets illuminated some, as well as the reticle lines. Of course, the proper way to use this feature in the field is to run the lowest illumination that you can see, so this really isn’t a problem.
My shooting buddy, Otho, has eyes that cannot see through most scopes clearly even with corrective lenses. But all the Leapers models have a very extended eyepiece adjustment that suits him fine. When I sight through his scopes, I have to make gross adjustments to keep from seeing double reticle lines. Only the Leapers scopes have enough adjustment so that both of us can use the same scope.
Lockable reticle adjustments and adjustable zero
Back in the bad old days, we would adjust our reticles until they were perfect and then never let anyone near our guns. I’ve had people grab one of my airguns off my tables at a show and start twisting both adjustment knobs with abandon. When I asked them what they were trying to do, they said they didn’t know — they just wanted to see how the knobs felt!
Well, the Bug Buster’s knobs are locked in place with collars that screw down tight after adjustments have been completed. That gives me time to snatch my rifle back from someone before they can screw up my scope setting.
The scales on both adjustment knobs can be loosened and repositioned so your sight-in is shown as the zero point on each scale. Then, if you have to adjust the knob in the future, you always know where to return.
Below the scale of each adjustment knob is a thin collar that can be turned down to lock that knob from turning. This protects your scope adjustment. You can also loosen the small Allen screw on top of each cap and slip the scales to keep the settings as your zero point.
Flip-up scope caps not useful
The Bug Buster comes with flip-up scope caps that I find less than useful — especially on the objective lens. Since the AO requires the objective lens to twist, the flip-up cap is never in the right position and will just get in the way. I take both scope caps off when using this scope because I can’t be bothered with them. If the AO were a sidewheel, then flip-ups would make a lot more sense to me.
The Bug Buster is a compact scope. As such, the scope tube sections where the scope rings attach are very short. So the rings have to move to where the scope needs them to be, because there isn’t a lot of extra scope tube on either side of each ring. A one-piece mount is all but impossible to use, as the location of the rings would only line up with the scope tube by coincidence.
Many airguns do not permit a scope to be mounted far enough to the rear for the eye-relief to work with a short scope like this. You have to consider that when mounting a Bug Buster or any compact scope. If the gun has a scope stop plate or vertical stop hole located far forward, it probably will not work with a Bug Buster. But if the top of the gun is wide open, like on the Rainstorm 3D bullpup, then it’s what you want.
The new 3-9X32 AO Bug Buster is the best one of the entire line. It offers more flexibility, yet comes in the same compact package as all the other Bug Busters. It meets a specific need in the scope world, yet still provides enough flexibility to work on many airguns.
