Maven RS1.2 2.5-15x44mm Field Eval

[Formidilosus]

This is a field evaluation of the Maven RS1.2 2.5-15x44mm SHR-Mil reticle scope. This scope was given to me by Ryan. The baseline 30 round group with this lot of ammunition was 1.5” at 100 yards.



The scope and weight-






Turrets:


Elevation turret is exposed, revolution indicated, 10 mils per rev, zero stopped, and tool less reset. Zero stop requires a tool. Windage is capped, revolution indicated, and tool less reset.


Elevation-




The top of the turrets unscrew from the rest to allow reset. The windage turret is identical-




Zero stop is simple pin on pin.



SHR-Mil reticle:
2.5x-



15x-



Illuminated-:

3x max illum-



15x, setting 4 of 10-



The reticle is good from a visibility perspective. The heavy stadia are 5 mils from center, with .5 mils spacing between increments. It has a center dot with on open center, and the first hash mark at .5 mils is where where the vertical and horizontal stadia lines begin.



Con’t….

Scope #2

Zeroing:

Zeroing went without issue. Boresighted and fired one round at center dot. Used the reticle and measured the correction. Dialed it and fired the reminding 9 rounds at the left dot. Adjusted up .2 mils (should have been .1 mil), and left .3 mils Went back to center dot and fired 2 confirmers.



Drop evaluation:


For an explanation see- Scope Field Eval Explanation and Standards


The “test” consists of three 18” drops on a mat- one left/right/top with a shot to check zero after each drop. Then the exact same thing repeated from 36”. Then three drops on all three sides for nine drops on the last part- 15 drops total. This is not “abuse”. The 18” drops are a joke really. The 36” start showing something. And when a scope make/model consistently goes through the whole thing without losing zero, failures in actual use are almost unheard of.

This one was conducted on packed, semi crusted snow.


Zero issues.






After walking up to take pictures, it was obvious that the initial 9 round group was .1 mil low and not .2 mils. Hence the reason for the slightly high group on the drop portion. I adjusted down .1 mil and went straight to the RTZ.

RTZ: 2,000+ mils dialed





Adjustment (tracking).

Used the reticle to measure between the bottom and top dots as 7.4 mils.

No issues. All rounds landed well within what can be observed with 10 live rounds.



Bottom (zero)




Top-








Initial conclusions:

There were no issues from start to finish. The scope behaved as a scope should.

 

[Formidilosus]

Reticle:

Visible at all powers. At 2.5x to about 4.5x it’s just a standard duplex that is no problem on broken backgrounds and low light. On 5’ish x to 15x it is a very solid mil reticle with a center dot. It is visible and useable at all powers, is not complicated or busy, and yet has the information one needs for hunting to hold elevation and wind. Quite frankly it is probably the best general FFP mil reticle on the market.





Eyebox:

It’s good. No issues at all. On the better end of the spectrum.




Usability: DOF, clarity, etc.


DOF and parallax are not finicky. Resolution, clarity and brightness are all good. It’s quality upper range Japanese LOW glass. No problems or complaints at all.

 

[Formidilosus]

Scope and rifle rode in the truck without padding and with gear and packs on top for the last couple of weeks.

Zero check yesterday-





Unmounted and remounted it on the gas gun.





Fired five rounds (upper left), used reticle to measure, adjusted and fired five more-




Still nothing negative noted about the scope.

 

[Formidilosus]

I have had the first RS1.2 prototype that was made since early summer. It was not to be publicly known as Maven wanted to see how it did. Ryan has spoken with Maven about it and both parties agreed it was acceptable to discuss the history briefly.


In short, the prototype worked. It passed multiple Drop Evals and held zero with a slight increase in group size. Baseline groups were 1.2-1.4 MOA, and groups while dropping from 36” were 1.6’ish MOA. The scope was mounted on a precision gas gun for most of that time and has around 1,000 rounds or a bit more on it.
In the last 6-7 months this scope has by far taken more use and abuse than any scope in that time. It rode in a truck bed drawer for 6-8 thousand miles with no padding and on top and under tools, axes, ammo, etc. It been dropped probably a hundred times between the Evals and field use. It’s killed animals at short range and at 1,106 yard, and has been shot passed 1,400m.


Scope #1











Then mounted on the 6UM-






Then after being in the back of the truck during a wreck-



Carried and used quite a bit-



Then 1,106 yards-

 

[Formidilosus]

Scope #2 Zero check-




Has ridden under and on top of gear since dec 28th- close to a thousand miles.

 

[Formidilosus]

Scope #1. Swapped the 6UM into the RokStok for a hunt. Zeroed and velocity trued at 960 yards.

 

[Formidilosus]

Scope #1-

782 yards-





390 yards-

 

[Formidilosus]

Scope #2 zero check after another 800 miles with gear being piled on top of it-

 

[Formidilosus]

A bunch more shooting out to 1,100 yards on 2nd scope-

 

[Formidilosus]

Zero check, scope #2-

Feb 22



March 11

 

[Formidilosus]

Zero check scope 2, March 16th-

 

[Formidilosus]

Zero check scope #2:




And a single 3 round group for the internet people-

 

[Formidilosus]

Zero check #2:




At this point I should move the zero down .1 and left .1 mils. That isn’t a shift, it’s just the nature of zeroing off of a 10 round group. There is something between 35-40 shots in that group now.

 

[Formidilosus]

Zero check after a 1,000’ish miles and being covered by gear-




Then shooting some 3 shot “groups”-

 

[Formidilosus]

Scope #1 replaced a failed scope on a students rifle at the S2H course and worked correctly out to 864 yards for more than 500 rounds.





Scope#2 worked correctly at the same course.

 

[Formidilosus]

Scope #2 is around 1,500 rounds in IIRC.

Zero check today after a couple thousand miles of travel-

 

[Formidilosus]

Scope number one and two were used for part of the last S2H class- about 200 rounds for #2 and 400 rounds for #1. #1 took a massive hit when a cliff boulder gave out and it slammed into the rock under full body weight. The slab that’s being shot off of, used to be attached a couple feet higher and to the right.



Scope (and rifle) has some more scratches, cuts, and rashes now; and the scope has a good dent in the objective bell-






However- it stayed zeroed,




I’ve seen 14 or 15 of these used the last two weeks for a combined 15,000 +/- rounds- they work.

 

[Formidilosus]

Scope #2 zero check-

 

[Formidilosus]

Scope #1 was put back on the Drop eval rifle, and used to compare to another scope. Elevation started .1 mil high on drop eval.

Three full drop evals here- that’s 36 times dropping it from 3 feet-



Note: first drop eval was per standard. 2nd and 3rd was the 18” drops back to back, then a shot, then three 36” drops with a shot after each, then the 9x36” with a shot after.
