Most Helpful Negative Review Poor workmanship
It looked ok out of the box but could not rotate the magnification very well. It stuck at a certain point and had to take off my rifle to turn. I've read other poor reviews as well. Think you'd be better suited with something else.

by Frank, Verified Owner from GA, United States Written on August 5, 2025

Pros:
  • NONE !
Cons:
  • everything
Best Used for:
  • PAPER WEIGH

Poor quality

by Old Vet, Verified Owner from CO, United States Written on July 15, 2025
I had it cloverleaf at 75 yards for testing, fire 10 rounds rapidly then settle in and put 3 in paper to double check zero and it moves the impact by 1/2 inch, repeat trial 2 more times, same result. Would never keep the zero. Very disappointed especially since this item is t cheap
Pros:
  • Looks cool
Cons:
  • Won't keep zero
Best Used for:
  • Cosmetics
Would recommend: No

Red dot not able to adjust .

by Charles, Verified Owner from TX, United States Written on February 5, 2024
I got this small scope mounted to a 9mm rifle. I sighted in the scope just fine , but when I was trying to adjust the RED DOT it did not have enough range for adjustment as it is fixed on top of the 3x9x40mm scope. the closest I could get it sighed in I was still 8" left of center of target with no more room to adjust. I thought it would be a cool scope as it had both red dot and scope together.

great product and price

by Unholy Sam, Verified Owner from WV, United States Written on September 2, 2021
I used it on my 300blkout and have had no problem with it. It was easy to sight in and east to inquire your target or dinner. The red dot works great and nice when transitioning from scoop to red dot.
Would recommend: Yes

great scope for the money

by suds, Verified Owner from RI, United States Written on October 14, 2020
I had one of these years ago on another rifle I sold and always wanted another one.
Fits nice on my 300 black out.
My gun case is small so it is nice that this scope has quick release to take off to get my rifle to fit in case.
The red dot is nice also, not an expensive red dot but is does the job, also like the P4 sniper reticle.
Pros:
  • quick release
Cons:
  • None
Best Used for:
  • Range hunting or any shooting needs
Would recommend: Yes

Realmannotasissy

by Jay, from TX, United States Written on December 9, 2019
The magnifying knob was hard to turn but not impossible. I turned mine to the highest possible power. I believe it's 9 so really I don't need to go any lower than that. I love mine. I raise my head to let the reddot get me around what I want to shoot. Drop my head back down to the scope and Bam Bam Bam. Rat that tat I can hit a head size target at 200yards like it was right in front of me. Not even trying hard. For the money I say get this one. Unless you have girly hands.
Pros:
  • Works great
Cons:
  • The reddot is kinda cheesy
Best Used for:
  • AR-15
Would recommend: Yes

Perfect fit for the 300 BO

by parthelynx, Verified Owner from OH, United States Written on January 1, 2018

Pros:
  • two aiming devices in one
Cons:
  • a bit heavy
Would recommend: Yes

Vism NcStar is still cheap.

by Prepper Overwatch, from TN, United States Written on April 14, 2017
The red dot on this is totally garbage with the bottom exposed and Scotch tape over the wires. Also, the mount allows the scope to shift forwards and backward, and I had to 'shim'it. Glass quality is fairly good,and the scope controls are easy to use. Overall, not worth 159.99, and I won't be buying this brand in the near future.
Would recommend: No
