- Elevation turret and windage turret are both uncapped and pull out to adjust, push in to lock. Both are 1/4MOA adjustments with 3 hashes in between whole numbers.
- Elevation turret is marked 0-24, with three additional hash marks (1/4, 1/2, 3/4) and 0 would equate to 25MOA per revolution.
- Windage turret is marked per direction; 1L, 2L, etc. / 1R, 2R, etc.
- Parallax is 10yds - infinity, it seems to line up appropriately.
- Illumination is 6 brightness settings with an off in between each (the solid dot on the dial is off). I think it was sunny day bright. The upside down horse shoe, center cross hairs, and "tree" illuminate.
- Occular focus in just the end ring of the eye piece; I think this is called european style rather than the whole ocular barrel moving for the focus.
- Zero stop is a brass rin around the erector with set screws. Loosen the set screws, rotate the ring clockwise so a square block on it hits a square block on the erector, then tighten the set screws.
- Windage and elevation turrets have the typical coin/flat head scew to hold them in place and "reset" to zero.
The scope was mounted on a Tikka T3 action with a 22BR Preferred Barrel sitting in a Bell and Carlson stock. It is the same everything (except for scope , duh) as in my prior tests.
Nightforce SHV f1 ,
Bushnell LRTSi 4-18 , and
Maven RS3. The rifle and load shoot more than adequate for this testing. "Witness marks" were drawn on the rings/scope body to show if the scope slipped or not.

To sight in, I pulled the bolt and looked through the bore, and adjusted the cross hairs. It probably doesn't matter in the grand scheme of things, but the
Maven RF.1 and
Maven CRF.1 both read 103 yards from bench to target.
- Low about 1.5" and left about .5" -->adjust 6 clicks up 2 clicks right
- .5" and a bullet diameter low, no adjustment
- 1" low, no adjustment
- 1" low, no adjustment
- 1" low, no adjustment
- 3/4" low 1/4" left, no adjustment
- 3/4" low 1/8" left, no adjustment
Shots 2-7 are all within the 1" square below the bull. I then made 4 clicks up.
Shots 8-12 were all within the 1" bull and made with no adjustments. The elevation turret was then removed, zero stop set, and turret set to 0. The windage turret was removed and set to 0. I made 10 clicks of vertical adjustment, which should have been 2.5MOA. It is possible that the cold bore (shot #1) was at the upper extreme of the cone of fire.
When setting the target, a 3' carpenter level was used to mark plum and level on the cardboard. On the plum line, two bullseyes were set 2' 10 9/32" center to center (34.28").
34.28" / .26 (I used .26" as 1/4MOA) = 131.84 clicks
131.84 clicks / 4 clicks per MOA = 32.96MOA
*Someone may come a long and tell me something about my math, but I am really proud that
@TheViking and I figured that out with no error shots.
For tracking I aimed at the bottom bullseye firing a shot at 0, turning the elevation dial past a full revolution to 8 (25+8 = 33MOA) and fired aiming at the bottom bullseye. The plum line was used to keep the reticle plum to the best of my ability. I then returned the turret to zero, shot, turned the turret past a full revolution to 8, etc. I ended up firing 10 into the low bullseye and 10 into the high bullseye.
The center of the upper bullseye's group was about 1 1/4" higher than it should have been, at about 35.5ish" from the lower bullseye. I think that is an error of 1.25MOA. 1.25MOA error / 33MOA input = 3.78% error
*if my mathing is correct*
It also ended up about 1/2" left, but whatever, I don't want to chase that monkey.
