I’ve tried out a few Maven scopes over the years, the RS1.2 has some classic Maven features and some optical improvements.   Maven’s RS.1 Riflescope series is intended for hunters seeking enhanced precision and versatility.   The RS1.2 is a first focal plane scope with a 2.5-15X zoom range, side parallax adjustment, and a milliradian or MOA-based reticle with illuminated center dot.  I prefer milrads myself, and evaluated the mil version of this scope.

Outside, the scope features a capped windage turret, a true zero-stop, and a dialable elevation turret with revolution indicator marks.  The knobs can be slipped to zero without tools by unscrewing the top portion of the knob (the top 2 rows of knurling).

Maven’s business model is a “direct to consumer” approach, which means you don’t find their optics in retail outlets, and your buddies who only buy scopes from the local gun store have probably never heard of them. Most companies use the traditional retail model of selling their product, which means a markup of around 50% is added to that item at the retail level. Since Maven cuts out the retail middleman, they can provide higher quality at a better-than-retail price.

The Maven RS1.2 is built on a 30mm tube with Extra-low dispersion ED glass and an etched reticle.  The scope is Nitrogen purged, waterproof and fogproof.

Comparing apples-to-apples, let’s pit the RS1.2 against 2 similarly-priced, illuminated FFP optics with similar features and magnification ranges (out of courtesy, I will refrain from mentioning any names, but they are popular brands).

As you can see, the Maven RS1.2 compares favorably in performance, size, weight, and price to these other popular competitors.


To test the Maven RS1.2, I used an American Defense MFG throw-lever mount (medium-height, which is a bit taller than I typically like, but it’s what I had available). It was mounted on an Adaptive Defense Armory ADC-15 with 20″ DMR-profile barrel (chrome-lined, 5.56 NATO 1-7 twist), free-floating handguard, and Hiperfire X2S mod 1 Trigger. The barrel is brand new, unfired, so it isn’t quite broken in yet, but for some basic testing at 100 yds, I figured it would be fine.  I used a handloaded 62-grain BTHP which typically gives outstanding accuracy.
Sight-in was accomplished in less than 10-rounds. Adjustments were accurate based on mil readings from the reticle. This doesn’t surprise me, Maven optics have always had accurate adjustments in my experience. I have ladder-tested more than one of their scopes and never saw any unexpected deviation.


This scope showed minimal optical distortion.  In the image above, if you look at the left and right edges of the cardboard target, you can see the greenish-yellow on the left and purple-ish tone on the right.  That is chromatic aberration, but I actually attribute it to the camera I was using to look through the reticle, and didn’t observe it with the naked eye staring through the reticle itself.  The horizontally-stacked railroad ties that make up the front of this backstop are a dead-giveaway for optics with pincushion distortion.  Notice how they appear flat and parallel in this image.  That’s a good sign!   All variable power scopes exhibit some field curvature or spherical aberration which causes some distortion at the extreme edges of the image when the center of the image is clear.  These are also exaggerated in the image above by the effects of the scope camera, which uses angled windows to permit looking through the scope while simultaneously filming.   This is good glass.


The illumination in this optic is designed around the center dot, which isn’t “daylight bright,” but it is my opinion that hunters and other shooters taking real low-light shots don’t need that much brightness. Less is more. If you crank the illumination all the way up, in addition to the center dot, you will get some spillover illumination into the etched reticle and the “red flashlight effect” from the front of the scope. In practical low-light environments using lower settings, this won’t be an issue.  The scope offers 10 illumination settings with “off” positions between each setting.



Chromatic Aberration 5/5 Chromatic aberration (when high-contrast objects can be edged by blues and yellows) was not noticeable in this optic.  I attribute the little bit observed in the images to the camera unit, not the scope.

Distortion 5/5 No pincushion or “fish-eye” effect.

Eye Relief 4.5/5 The advertised eye relief of this scope is 86-100 mm,  a little on the tight side, but very usable.

Field of View 4.5/5 100 yard field of view is basically comparable with similarly-priced (and higher-priced) competitors at 41.7′ at 2.5X and 7′ at 15X.

Spherical Aberration & Field Curvature 5/5 Sacrificing a little field of view probably helps cut down on the apparent field-edge distortions.  All scopes have a little distortion at the extreme edges of the field due to the physics of bending light through curved glass lenses.  The little bit in this scope is nothing to complain about.

Features and Characteristics

Size & Weight 5/5 – Slightly shorter and lighter than the competitors, for hunters and other shooters trying to shave ounces from gear, that’s a solid benefit.

Illumination 3.5/5 – This is the only area where I have a bit of a hard time with Maven optics.  The illuminated center dot is only visible at high magnification in relatively dim ambient conditions.

Tactile Surfaces 5/5 – Solid and precise, tool-less re-zero, nice knurling throughout and a usable lever that doesn’t get in the way on the magnification ring.

Tracking: 5/5 – All Maven scopes I’ve tried have had perfect tracking.


In the world of optics, you can certainly do a lot worse.  While this scope has comparable features and performance to popular competitors (at a better price), Maven also has durability going for it.  These scopes are designed for hunters and intended to survive harsh field conditions.  They are backed by a Lifetime Warranty.  As an American company, that makes warranty service (if ever needed) a much more pleasant experience.  If you’ve ever had to send an expensive Austrian or German scope back to the factory, you know it is a painful and lengthy process.  If you are a precision rifle shooter who needs a hunting scope, I think you’ll find this Maven to your liking.  It has the precision optics characteristics you are accustomed to like good glass, a mil or MOA subtension reticle, side parallax adjustment, and a practical magnification range for its intended use, in a light-weight, durable body.
