Davis Power-Boosting Scope Lens Insert
Gene Davis has a new product that boosts the magnification of Leupold, Sightron, and Weaver BR scopes. A threaded ring with a Zeiss lens simply screws on to your scope behind the eyepiece, using the threads provided for lens caps. (Consider it an eyepiece extension). Both 2X and 3X models are available. The 2X version increases image size about 15% while the 3X boosts the viewed image roughly 30%. Hence, on a 36X scope, Davis’ 3X booster creates the equivalent of a 46X power scope. Starting with a 45X Leupold you can get 58X power. Many long-range BR shooters are using this product and reporting to Gene that they can see bullet holes at 600 yards and beyond for the first time. However, there is a price for the extra magnification–the reticle will appear slightly larger, and the image will appear somewhat darker. But, according to Gene: “the image darkening is almost imperceptible during prime daylight hours.” We think Gene’s invention is a winner–a great way to get more magnification at a low cost–$100.00. We also like the fact that, unlike an internal boosting job, you can simply remove the Booster if you want to return to the original magnification level.
Gene reports: “If the scope has screw-in lens caps, these Optical Boosters perform well. We started with a product for the Leupold Competition scopes. We now have Optical Boosters for Weaver T36 and Sightron 36BR as well. We are working on other brands of scopes and the earlier Leupold scopes that do not have threads for the cap. The Optical Boosters do a fantastic job for old or poor eyes. They fit any Leupold scope that has screw-in lens caps, as well as the Weaver and Sightron 36-power target scopes. The Boosters require no internal modification and will not effect the factory warranty. The Optical Boosters (either 2X or 3X) cost $100 delivered.” To purchase, contact Gene Davis at (740) 503-4486 or gdavis10 [at] columbus.rr.com.
Here are reports from two users:
Dick Wright: “Mine is on a 45X Leup…. It’s now a 60X Leup. I got it at the Super Shoot. Excellent optics. You have to re-focus the crosshair. I used it at the Oscoda match where we had lots of mirage. It was a 200 yd. score match and I could see my .22 bullet holes easily. This is totally subjective but, if anything, it made it easier to see. It’s an optical booster that really works for a mere [$100] bucks. All you have to do to reverse the process is un-screw it.”
Joe Pellegrene: “I just got back from the range using my new 3x magnifier on a 45x Leupold. Now it’s a 60x scope and I can’t imagine how I ever lived without it. If anyone’s having trouble seeing their bullet holes on the target this product is well worth the money. It’s easily the most significant piece of equipment that I bought yet.
I plan on using it on several different rifles since you just unscrew it and screw it on the next one. It that takes about 10 seconds to do that. The fine cross hairs on my Leupold were magnified, but so was the target so everything seemed proportional. It’s so much nicer seeing what you’re trying to hit. Now if only Gene would make one for the Nightforce scopes. You can put me down for one Nightforce magnifier. Gene, I wouldn’t mind shooting a 56x Nightforce!”
Would buy this for the Nightforce scopes.
Gene,
I would buy this for my Nightforce scopes – both Benchrest and NXS. Allowing for Zeiss quality I would also buy this for my 6-24 x 72 Zeiss and my 5-25 x 56 S&B PMII.
If tooling is an issue for the S&B/Zeiss – PM me on cost as I would consider meeting this.
How can I order a lens And can I still use my sunshade?
Editor: Contact Gene Davis (links and phone number in article).
Yes, you can still use your sunshade. The booster ring screws in the rear of the scope, between the end of the scope and the shooters eye. It is basically an eyepiece extension.
i would be interested in this for both my zeiss 6 x 24 victory model and my nightforce 12 x 42 nxs…
Gene…I discovered that your lens will screw into a Leupold variable
only if it one of the black versions…in other words it will not screw into a 6.5 x 20 silver …Ithink that is kind of interresting…has to be the difference in the coatings Leupold is using….I tried it on two different balck and two silver…same results…no go on the silvers…great value fantastic
Stumbled accross this posting and have been doing the shiloutte thing for a while. I have burris 8-32 with no threads… anything for this scope? I am also looking @ a weaver (silver)36x,… someone mentioned that the finishes differ? Black to silver? Looking @ a weaver and the m8 leupold 36 power both silver. What are your thoughts? thanks Mark.
Gene I bought one of your OB for my 45x-45 Leupold from a distributor. I really don’t see much difference. Marking the target edges the optical picture remains the same picture with and without. The image does not get closer. I did have to refocus a little bit to get the crosshairs in focus. What am I doing wrong?I am trying to offset the start of cataracts.
Thank You

very interesting, but I don’t agree with you

Is there any reason this could not be modified for the Burris line of scopes ie. Black diamond and Sig Select scopes?
I am interested, and Would like to know if this can be used/ and fits to an Aimpoint Comp ML2….
Is the lenses piece threaded on both sides? In other words, can you thread a lenses cover onto this eyepiece?
I use Leupold Lumina flip lenses covers, so I would want to be able to thread my lenses covers onto this eyepiece.
TARGET SCOPES from 6mmBR.com
Exit Pupil: Given objectives (front lens elements) of equal size, the more magnification the scope, the smaller the exit pupil. Remember that the exit pupil, a tiny circle of light, must deliver ALL the optical data your eye receives. Bigger is better by far.
Too small an exit pupil will make a good scope dim and hard to use.
That’s why we advise against boosting the Weaver T-36 or the 36X Sightron.
With their respective 40mm and 42mm objectives, the exit pupil becomes too small when they are boosted beyond 36x.
WIll this work on an intermediate eye relief scope like the Leopold or Burris Scout?
DOes this work with a Leupold Mark 4 E\RT 6.5x20x50?
Sorry but this e-mail doesn’t work anymore! gdavis10 [at] columbus.rr.com.
I don’t know what to do to contact this person.

Gene, Will this work on a Leopold 6.5x20x40mm. Do they come in a black matt? What power would it give me?
Thank you John
I know this information is somewhat dated, but I’m wondering if you make these power boosters for Vortex Razor scopes?
Do you have one to fit a Athlon Argos 10x40x56 rifle scope? THANK YOU!
