Q&A here https://www.rokslide.com/forums/threads/maven-rs-3-5-30x50-ffp-mil-mil-q-a.251009/

Maven RS.3 5-30x50mm evaluation. The test rifle is a 22BR Tikka T3 with 200ish bullets down the tube. It has shown to group under 1.5" for 10 shots at 100 yards in that time. The scope was sent to me by Maven to fiddle with and I had permission to drop it. @HawkinsPrecision rings, a Talley rail, and Grayboe Phoenix completed the setup. I had talked to @Ryan Avery a few weeks ago and he said that @Formidilosus was working on other Maven RS.x evals as this scope was being shipped.

Weight
The scope is listed at 26.9 ounces, I weighed it at the post office and it was close enough I did not take a picture. https://mavenbuilt.com/collections/riflescopes/products/rs-3-riflescope-5-30x50

Turrets
Both elevation and and windage are exposed and reset without tools by the end 1/4 of the cap unscrewing. Elevation has 6mils per revolution, marked 0-5,revolutions are not indicated, and windage has 0, 1L, 2L, 3, 2R, 1R. Click for both are .1mil and marks on both turrets exist for each click. Parallax is marked 20, 30, 40, 50, 60, 70, 100, 150, 200, 300, 500, 1000, infinity. The zero stop is a jam nut with a slotted screw for tightening, a WIHA slotted bit is included for the zero stop.

Zero and Return to Zero
@HawkinsPrecision rings and the built in level on the stock co-witnessed, when mounting I am as certain as I can be that the reticle was leveled to match. I had put a few on target earlier in the week and knew the zero was really close. The evaluation was done with a front and rear bag, outdoors near Como, Colorado at about 9500'asl and 40degrees temperature variable wind throughout.


These stickers are 3" across, and the inner marked circle is 1.5". Cold bore and follow up were shot (1, 2), adjustment of .2mil to move impact left was made, three shots (marked 4-6) were then taken. A final .1mil adjustment to move impact right was made. The caps were reset to indicate zero and the zero stop set. I just now realized that we forgot the number 3 existed (doh!), but only 5 shots were made on this spot.

I took a 3' carpenter's level and marked the carboard with plum and level in a few different areas once the cardboard was mounted. From zero, there was about 3.4 full revolutions left on the adjustment. The elevation turret was turned until it stopped at the top end and then returned to zero at least five cycles accounting for a little over 20mils of adjustment each way. So, 20x2 = 40, 40x5 = 200mils adjustment at a minimum, if I got distracted talking or lost count I started over on the count. A picture was taken through the spotter after each shot, and the first four shots were marked because shot 4 was hard to see through the spotter. Shots 5-10 were not marked as it was easier to see their holes through the spotter.

Tracking
Using the reticle to measure, I had a little over 5 mils up and down on the cardboard available. I loosened the zero stop, and dialed down 5 mils on the turret and then reset the zero stop. This placed my bottom 5 mil value at "1", zero was still "0", and "5" would be my upper value. I shot down first, then up, then down, etc. all aimed at the left green circle. Photos were taken in between each shot through the spotting scope.

I rough measured these with a laser when I got home to get an approximation, and then later measured with a tape to where I thought the center was. 5 Mils should be 18".
~19" for the upper group = 105.55% value
~18.25" for lower group = 101.38%

I also measured off the plum line at 1.535" to the center of the POA green circle., and compared that distance off the plum line with each group.

Drop Evaluation:
The range was compacted and very hard dirt. I laid out two 1/8" dense foam pads folded over a few times and removed any rocks from underneath. 18" drops were done from my knee height, 36" drops were done from waist height. This process was videoed using the phone skope, link below. Prior to dropping, a zero "proof" shot was taken at the intersection of plum/level below the RTZ circle. It is ~.6" low left of that intersection and can be seen in the video.


Drop testing POA was the left green circle, the same POA as the tracking test.
-18" drop on windage was left of center ~1.5"
-18" drop on elecation was on POA center
-18" drop on parallax adjustment was not on the cardboard anywhere
-36" drop on windage was right edge of cardboard ~1'
-36" drop on elevation broke the rifle's stock.

The cardboard. Measurements written for the tracking groups were what I came up with using my laser and hand, what I stated above is more accurate.

I have the rifle in a different stock and will resight in this week and test at lower drop heights this weekend (maybe).

In hindsight, I should have rezeroed after the drop on the parallax side was off the cardboard. I wanted to keep the video continuous as that seemed to be a complaint by some of previous testing in that there was no video, I surmised if there was cuts in the video people would complain.

After viewing the video a bunch of times, I think the parallax drop moved the impact off the cardboard to the left.

Subsequent testing willstart at 18" on the windage and elevation again, and then 36" on the windage and elevation. I believe there is a chance thee will be on POA. If those are on POA, I will test drops on parallax at 6", 12", and again at 18".

Subjective
I was surprised at how un-finicky the eyebox as at 30x. It was particular, but my expectations were for it to be a pain to get behind. I was shooting early afternoon and into the sun with a lot of glare, and it wasn't bad at all.

The jam nut style zero stop is sort of a pain in butt. I was finding a need to set it a few times because if it is too snug, then there is resistance and not a warm and fuzzy solid click into the stop. Too loose and it almost feels like it gets past the click into zero. The slotted screw to hold the zero stop should be hex in my opinion, mine already has some owies but I am notorious for stripping heads.

Everyone can draw their own opinions and conclusions on the dropping. For those who want to see shot by shot, I can share them in the q&a thread, but I don't really think they are needed.

Replaced the stock and proofed rifle see here

Reinstalled Maven RS.3 on the rifle and checked the zero. The action changed stocks, and I can't remember what pic slot I had it in before. Shots were left ( right black circle) so a .2mil correction was made.

Shots 1-3, the 18" drops, were good with two and three touching.
