Reviews & Ratings for NcSTAR MARK III Gen3 Tactical 3-9x40 Rifle Scope
— 4 reviews — Page 1
Works great. Lots of features for the price. I'm leaving a review to comment on the mount - I had read in a few places that this mount was a loose fit and sometimes impossible to tighten. There is a screw that goes under the scope and a nut on one side that appears as if it's how you tighten it. It ...

Will not hold zero. Myself a d another ra gemaster had similar results testing it. Would not hold consistent groupings. Perhaps due to the cheap mount. It is the weakest link of this system. Just a cheaply done mount. Glass could be clearer but is ok. Nothing to use fir anything but plinking.

Looks great on my weapon. Easy to sight in. Nice clear optics. I would but again. The footprint for the red dot is proprietary to the NcStar brand and is not universal.
Pros:
None
Cons:
Red dot footprint
Would recommend: Yes

I left a review on this after shooting it just once or twice. After I recently purchased a bipod, though, it became obvious this scope is not accurate at all. I can set the rifle perfectly steady on the bipod and, if I move my eye around behind the scope, I can see the crosshairs move around on the target up to 2 inches in either direction. Hopefully that explains why my groups are 5 or 6 inches wide at 50 yards. Also, the target just isn't nearly as clear & crisp as the $100 Sig Sauer scope on my other rifle. Also, my Sig Sauer scope's crosshairs don't move around at all when I move my eye around behind it. I'll be buying a different scope and throwing this one away.
Pros:
None
Cons:
crosshairs move around
Best Used for:
Paperweight
Would recommend: No
