There I used to be, with a JAKL-10 and a field stuffed with purple dots and fixed-power prisms. I felt I wanted one thing extra applicable for a .308 rifle. This led me to the Maven CRS.3 4-20×50 scope. I needed to deal with the gun like a DMR rifle, and it wanted some critical magnification. I bounced between a number of completely different settings however in the end needed to have the ability to hit small targets at lengthy vary. Nobody desires to spend greater than needed, however I wasn’t settling for the bare-bones funds choices.

The CRS.3 is priced at $700 and gives a exceptional array of options for the cash. The 4-20x50mm optic comes with both a MIL or MOA reticle. I went with MOA as a result of I’m no PRS shooter, and MOA is just simpler for me to grasp. The CRS.3 4-20x50mm boasts an illuminated reticle, fingertip-adjustable turrets, and is a primary focal aircraft (FFP) scope. It comes with all of the premium options you’d count on.
It’s nitrogen-purged, fogproof, waterproof, has a part correction coating, an etched reticle, and a lifetime guarantee. These optics are assembled within the Philippines with high-quality Japanese glass. Maven describes it as a mid-range mannequin, and curiously sufficient, they don’t use conventional retailers, choosing direct-to-consumer gross sales solely. I hit the bottom working with the CRS.3 mounted to the JAKL.

Zeroing The CRS.3
The turrets make this factor an absolute pleasure to zero. With the optic mounted, I took my time taking photographs and was fortunate sufficient to seek out that the optic wasn’t all that far off from the place the gun was capturing. I needed to make solely minor changes, and I used to be on the cash. The turrets are fingertip-adjustable and supply good tactile and audible suggestions with every click on.

The changes are ¼ MOA per click on. I stabilized the rifle at 100 yards after which checked the monitoring. I fired a bunch, then adjusted 4 inches down, fired one other group, then adjusted 4 inches left, and fired a 3rd group. Issues wrapped up by adjusting 4 inches up and 4 inches proper, firing a last group. The ultimate group was nearly dead-on with my first group. If you happen to checked out it, you’d swear it was one single group fired by a mediocre shooter.
I’m most definitely a mediocre shooter, so the optic carried out superbly. The CRS.3 tracks exceptionally effectively, and all of the teams completely coincided with the four-inch low and four-inch left changes. With the optic zeroed, I received to exit to 500 yards and observe some slow-fire capturing. The CRS.3 comes with an adjustable parallax, which makes it straightforward to make sure we’re all on the identical aircraft when capturing at various distances.

At 500 yards, the 20X magnification delivered superior readability downrange. I might simply see my targets, make out all of the completely different colours of metal, and put rounds proper the place I needed them to be. Properly, principally—any misses have been definitely on me, not the optic. The optic’s sharp readability and etched reticle made it surprisingly straightforward to make that metal ring.
Going Clear
Sadly, my state seemingly lacks correct long-range capturing ranges, so most of my capturing was completed inside 200 yards. Nonetheless, I’ve loads of fields to scan and observe how far and extensive the optic can see. The view by way of the optic stays extremely clear, even at longer commentary distances.

There is likely to be faint traces of chromatic aberration, however they’re so minor that they’re barely value mentioning. The glass is obvious from edge to edge, with no noticeable distortion. Colours stand out remarkably effectively when searching at lengthy ranges. You may simply pick completely different shades of inexperienced in an unlimited subject of comparable greens. If I have been searching a deer in a pine forest, I’m assured I might pick the deer’s brown coat in opposition to the brown of the pine bushes with ease.
Taking pictures Quick With the CRS.3
I not too long ago shot the Division of Power Designated Marksman qualification with the JAKL-10 and this CRS.3 optic. This demanding check requires capturing at numerous ranges and from numerous positions. I needed to shoot precisely whereas shortly altering positions at ranges from 100 yards down to fifteen yards. The sleek magnification vary of the CRS.3 and the micro-sized throw lever made it fast and simple to get into motion and adapt to altering distances.

The reticle’s illuminated portion was barely seen at excessive midday in Florida. It’s definitely not as vibrant as a purple dot, but it surely’s simply seen sufficient to be helpful. It’s not eye-catching in vibrant situations until you’re in low mild. I don’t personally assume the optic wants an illuminated reticle, however hey, it’s there. A characteristic I actually recognize is that the illumination settings have “off” positions between every brightness stage, permitting for fast toggling.
The optic appears strong sufficient to take a beating. It endured loads of standing-to-prone transitions and was bumped round with out shedding or shifting its zero. The turrets don’t have a zero cease, however they didn’t shift throughout use, and the numbered and hash scale current on them makes it straightforward to trace in the event that they have been to maneuver. Resetting the turrets to zero is an easy course of and really straightforward to do.

We get beneficiant eye aid with this optic. At 4X magnification, it runs between 3.4 and three.9 inches. At 20X, we get 3.1 to three.7 inches. Each ends of the magnification vary provide beneficiant eye aid, making it quick to get behind the scope and purchase your goal. It was essential to remain inside the strict deadlines of the DOE qualification, and I didn’t have an issue staying effectively inside the prescribed deadlines.
Closing Pictures
The CRS.3 is a rock-solid little scope in most regards. Nonetheless, I do have some minor complaints. The reticle will get fairly massive at 20X magnification. As you lengthen out to longer ranges, it might turn into a bit obtrusive. It begins to eat up your subject of view and might cowl smaller targets.

Whereas capturing at 500 yards isn’t an issue, relying in your goal’s measurement, you would possibly run into some points if you wish to push out to 800, 1,000, and even additional.
That’s my solely vital criticism, particularly contemplating this value level. The Maven CRS.3 is an actual performer for its value. Whereas it won’t be revolutionary, it’s a stable optic for an important worth.
