Most Helpful Positive Review Lots of features for the price
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 ...

Most Helpful Negative Review Looks good, wont hold zero
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.

I love it. Great scope for the price

by Jon, Verified Owner from MI, United States Written on October 26, 2025
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

Updating my last review

by GK, Verified Owner from MI, United States Written on February 26, 2023
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
